Trimester 02

40 Weeks to Enjoy (Second Trimester)

Your pregnancy: 13 weeks

How your baby's growing:

Fingerprints have formed on your baby's tiny fingertips, her veins and organs are clearly visible through her still-thin skin, and her body is starting to catch up with her head — which makes up just a third of her body size now. If you're having a girl, she now has more than 2 million eggs in her ovaries. Your baby is almost 3 inches long (the size of a medium shrimp) and weighs nearly an ounce.

How your life's changing:

This is the last week of your first trimester, and your risk of miscarriage is now much lower than earlier in pregnancy. Next week marks the beginning of your second trimester, a time of relative comfort for many women who see early pregnancy symptoms such as morning sickness and fatigue subside. More good news: Many couples also notice a distinct libido lift around this time. Birth is still months away, but your breasts may have already started making colostrum, the nutrient-rich fluid that feeds your baby for the first few days after birth, before your milk starts to flow

Your pregnancy: 14 weeks

How your baby's growing:

This week's big developments: Your baby can now squint, frown, grimace, pee, and possibly suck his thumb! Thanks to brain impulses, his facial muscles are getting a workout as his tiny features form one expression after another. His kidneys are producing urine, which he releases into the amniotic fluid around him — a process he'll keep up until birth. He can grasp, too, and if you're having an ultrasound now, you may even catch him sucking his thumb.

In other news: Your baby's stretching out. From head to bottom, he measures 3 1/2 inches — about the size of a lemon — and he weighs 1 1/2 ounces. His body's growing faster than his head, which now sits upon a more distinct neck. By the end of this week, his arms will have grown to a length that's in proportion to the rest of his body. (His legs still have some lengthening to do.) He's starting to develop an ultra-fine, downy covering of hair, called lanugo, all over his body. Your baby's liver starts making bile this week — a sign that it's doing its job right — and his spleen starts helping in the production of red blood cells. Though you can't feel his tiny punches and kicks yet, your little pugilist's hands and feet (which now measure about 1/2 inch long) are more flexible and active.

Welcome to your second trimester! Your energy is likely returning, your breasts may be feeling less tender, and your queasiness may have completely abated by now. If not, hang on — chances are good it will soon be behind you (although an unlucky few will still feel nauseated months from now).

The top of your uterus is a bit above your pubic bone, which may be enough to push your tummy out a tad. Starting to show can be quite a thrill, giving you and your partner visible evidence of the baby you've been waiting for. Take some time to plan, daydream, and enjoy this amazing time. It's normal to worry a bit now and then, but try to focus on taking care of yourself and your baby, and having faith that you're well equipped for what's ahead.

Decision Guide: Should you find out the sex of your baby?

Boy, girl — or big surprise? Sixty-four percent of mothers-to-be in a BabyCenter poll said they wanted to find out the sex of their baby ahead of time, while the rest preferred to wait. "We decided that the surprise of 'it's a boy!' or 'it's a girl!' is the same surprise at 5 months as it is at the birth," said Jessica. Michael disagreed: "I think the old-fashioned way is the best. Finding out before birth is like opening your Christmas presents before Christmas!" If you're still on the fence, here's a look at the pros and cons of each side. A word of caution: If you want to keep your baby's sex a secret, let your provider and the ultrasound technician know right away so they don't inadvertently blurt it out in the middle of an ultrasound exam or while reviewing your test results.

Benefits of finding out:

• Many women say they feel a deeper bond with the baby once they know the sex and can picture a little boy or girl.

• You can prepare an older sibling for the arrival of a new little brother or sister.

• You can narrow down your list of baby names.

• You can pick out a gender-specific nursery theme or baby clothes, if you want to.

Benefits of waiting:

• You, your partner, and your family will have a delightful surprise on the day you give birth.

• Your desire to know whether your baby is a boy or a girl might motivate you during the toughest parts of labor.

• You'll be following in the tradition of your parents, your parents' parents, and so on.

• There will be no mistakes — what you see is what you get!

Consider keeping the price tags on any baby clothes that are clearly for a boy or a girl until you see your baby for yourself. Ultrasounds aren't always foolproof at determining sex.

• How has pregnancy affected how often you have sex?

This Week's Activity:

Find a prenatal exercise class. If you haven't already, now is a good time to start a regular workout. Joining a class can help motivate you to stick with it. And many women find that prenatal exercise classes are a wonderful way to bond with and get support from other pregnant women. Some good options include water exercise, prenatal yoga or Pilates, a walking group, or a dance class designed for pregnant women.

Your pregnancy: 15 weeks

How your baby's growing:

Your growing baby now measures about 4 inches long, crown to rump, and weighs in at about 2 1/2 ounces (about the size of an apple). She's busy moving amniotic fluid through her nose and upper respiratory tract, which helps the primitive air sacs in her lungs begin to develop. Her legs are growing longer than her arms now, and she can move all of her joints and limbs. Although her eyelids are still fused shut, she can sense light. If you shine a flashlight at your tummy, for instance, she's likely to move away from the beam. There's not much for your baby to taste at this point, but she is forming taste buds. Finally, if you have an ultrasound this week, you may be able to find out whether your baby's a boy or a girl! (Don't be too disappointed if it remains a mystery, though. Nailing down your baby's sex depends on the clarity of the picture and on your baby's position. He or she may be modestly curled up or turned in such a way as to "hide the goods.")

You've probably gained about 5 pounds by now (a little more or less is fine, too) and are well into the swing of your pregnancy, but you may still be surprised by an unexpected symptom now and then. If your nose is stuffed up, for instance, you can probably chalk it up to the combined effect of hormonal changes and increased blood flow to your mucous membranes. This condition is so common, there's even a name for it: "rhinitis of pregnancy." Some pregnant women also suffer nosebleeds as a result of increased blood volume and blood vessel expansion in the nose.

If you're having amniocentesis, it'll most likely happen between now and 18 weeks. This test can identify hundreds of genetic and chromosomal disorders. If you're getting very anxious while waiting for the results, it may help to know that most women who undergo amniocentesis get good news about their babies — bringing welcome relief from their worries.

Don't be surprised if you and your partner are feeling a little stressed out these days. Many pregnant couples worry about their baby's health and how they'll handle the changes ahead. But with physical discomforts on the wane and energy on the rise, this is also a wonderful trimester for most women.

Your pregnancy: 16 weeks

How your baby's growing:

Get ready for a growth spurt. In the next few weeks, your baby will double his weight and add inches to his length. Right now, he's about the size of an avocado: 4 1/2 inches long (head to rump) and 3 1/2 ounces. His legs are much more developed, his head is more erect than it has been, and his eyes have moved closer to the front of his head. His ears are close to their final position, too. The patterning of his scalp has begun, though his locks aren't recognizable yet. He's even started growing toenails. And there's a lot happening inside as well. For example, his heart is now pumping about 25 quarts of blood each day, and this amount will continue to increase as your baby continues to develop.

The top of your uterus is about halfway between your pubic bone and your navel, and the round ligaments that support it are thickening and stretching as it grows. You're probably feeling a whole lot better as you settle into pregnancy, too. Less nausea, fewer mood swings, and "glowing" skin contribute to an overall sense of well-being.

Soon you'll experience one of the most wonderful moments of pregnancy — feeling your baby move. While some women notice "quickening" as early as 16 weeks, many don't feel their baby move until about 18 weeks or more. (And if this is your first baby, don't be too impatient — you may not be aware of your baby's movements until 20 weeks or so.) The earliest movements may feel like little flutters, gas bubbles, or even like popcorn popping. Over the following weeks they'll grow stronger and you'll be able to feel them much more frequently.

Feel your baby move "I wasn't sure if I could feel my baby moving, so a friend suggested I lie down for a while. After a few minutes, I started feeling a butterfly sensation in my lower abdomen. It was amazing!" — Linda B.

Your pregnancy: 17 weeks

How your baby's growing:

Your baby's skeleton is changing from soft cartilage to bone, and the umbilical cord — her lifeline to the placenta — is growing stronger and thicker. Your baby weighs 5 ounces now (about as much as a turnip), and she's around 5 inches long from head to bottom. She can move her joints, and her sweat glands are starting to develop.

Starting to feel a bit off balance? As your belly grows, your center of gravity changes, so you may begin to occasionally feel a little unsteady on your feet. Try to avoid situations with a high risk of falling. Wear low-heeled shoes to reduce your risk of taking a tumble; trauma to your abdomen could be dangerous for you and your baby. You'll also want to be sure to buckle up when you're in a car — keep the lap portion of the seat belt under your belly, drawn snugly across your hips, and also use the shoulder harness, which should fit snugly between your breasts.

You may also notice your eyes becoming drier. Using over-the-counter lubricating drops may help. If your contact lenses become uncomfortable, try wearing them for shorter stretches of time. If you still have discomfort, switch to glasses until after you give birth.

An easy way to keep track of the nutrients you need "I made a simple chart of the basic food groups and posted it on the refrigerator. At the end of the day, I checked off what I had eaten. Then, for my bedtime snack, I tried to pick something that would fulfill whatever category was lacking — yogurt (or a bowl of ice cream!) if I needed more dairy, for example, or an orange if I needed more fruit." — Anonymous

Dreams During Pregnancy

Many women report that their dream life shifts into high gear during pregnancy. Interestingly, during the second and third trimesters, you spend less sleep time in rapid eye movement (REM) sleep, the cycle in which most dreams occur. Why, then, all those frequent and vivid dream memories?

It's probably at least in part because you may be interrupting a dream-filled cycle when you wake up to pee, cope with heartburn, leg cramps, restless legs, or a backache, or to shift to a more comfortable position. Waking up during REM sleep makes you more likely to remember your dreams.

It may also be in part that dreams seem so vivid during pregnancy because for most women pregnancy is a time of such heightened emotions — from joy to apprehension and everything in between — but no one really knows for sure.

Here's a look at some common themes and what they may mean, according to Patricia Garfield, a clinical psychologist and author of Women's Bodies, Women's Dreams.

You're caring for baby animals. During the second trimester, many pregnant women dream about cuddly, baby-like animals, such as puppies, chicks, and kittens. Friendly creatures in your dreams are generally thought to signify that you're tuned in to your instincts. Menacing animals, on the other hand, may represent ambivalence about the strange new creature entering your life.

You have a sexy encounter with an old flame. Many mothers-to-be are concerned about their changing figure and its effect on their sex life — while many others feel more sexually charged than ever. Both feelings are often reflected in your dreams. Not only do erotic dreams offer comforting reassurance, but they may mirror the sexiness you feel during your waking hours, too.

Your mate is straying. If you dream that your partner hooks up with an ex-girlfriend or a total stranger, it can signal insecurity about holding his love and attention through a time of great change. Right now, you're dependent on the goodwill and support of those around you, especially your partner. Fearing his loss is a common emotional reaction to being pregnant.

Since there's nothing you can do to stop the crazy dreams, try having fun with them. Keep a notebook and pen by your bedside to jot them down.

This Week's Activity:

Start a baby name list. Make a list of ten names you like. Have your partner do the same. Trade lists and each cross out one name on the other's list that you dislike. Keep taking turns until you have a set of names you can both live with. Talk about why you like and dislike certain names. Many couples even create ground rules, such as no names of former girlfriends or boyfriends and no names that have ever been used for family pets.

Your pregnancy: 18 weeks

How your baby's growing:

Head to rump, your baby is about 5 1/2 inches long (about the length of a bell pepper) and he weighs almost 7 ounces. He's busy flexing his arms and legs — movements that you'll start noticing more and more in the weeks ahead. His blood vessels are visible through his thin skin, and his ears are now in their final position, although they're still standing out from his head a bit. A protective covering of myelin is beginning to form around his nerves, a process that will continue for a year after he's born. If you're having a girl, her uterus and fallopian tubes are formed and in place. If you're having a boy, his genitals are noticeable now, but he may hide them from you during an ultrasound.

Hungry? An increase in appetite is pretty common about now. Make it count by choosing meals and snacks that are rich in nutrients instead of empty calories (chips, French fries, candy, and other sweets). Bigger, more comfortable clothes are a must now as your appetite and waistline grow.

Your cardiovascular system is undergoing dramatic changes, and during this trimester your blood pressure will probably be lower than usual. Don't spring up too fast from a lying or sitting position or you might feel a little dizzy.

From now on, when you do lie down, it's best to lie on your side — or at least partly tilted to one side. (When you lie flat on your back, your uterus can compress a major vein, leading to decreased blood return to your heart.) Try placing a pillow behind you or under your hip or upper leg for comfort.

If you haven't already had a second-trimester ultrasound, you'll probably have one soon. This painless procedure helps your practitioner check how your baby's growing, screen for certain birth defects, check the placenta and umbilical cord, determine whether the due date you're working with is accurate, and see how many babies you're carrying. During the exam, you might see your baby moving around or sucking his thumb. Bring your partner along, and be sure to ask for a printout for your baby's first photo album!

Afternoon energy booster "If you're finding it hard to get through the afternoon at work without a little nap, find a place you can escape for 15 to 20 minutes (close your office door, use a conference room, even sit in your car).

Your baby's sensory development is exploding! Her brain is designating specialized areas for smell, taste, hearing, vision, and touch. Some research suggests that she may be able to hear your voice now, so don't be shy about reading aloud, talking to her, or singing a happy tune if the mood strikes you.

Your baby weighs about 8 1/2 ounces and measures 6 inches, head to bottom — about the size of a large heirloom tomato. Her arms and legs are in the right proportions to each other and the rest of her body now. Her kidneys continue to make urine and the hair on her scalp is sprouting. A waxy protective coating called the vernix caseosa is forming on her skin to prevent it from pickling in the amniotic fluid.

Think you're big now? You'll start growing even faster in the weeks to come. As a result, you may notice some achiness in your lower abdomen or even an occasional brief, stabbing pain on one or both sides — especially when you shift position or at the end of an active day. Most likely, this is round ligament pain. The ligaments that support your uterus are stretching to accommodate its increasing weight. This is nothing to be alarmed about, but call your practitioner if the pain continues even when you're resting or becomes severe.

You may be noticing some skin changes, too. Are the palms of your hands red? Nothing to worry about — it's from the extra estrogen. You may also have patches of darkened skin caused by a temporary increase in pigment. When these darker patches appear on your upper lip, cheeks, and forehead, they're called chloasma, or the "mask of pregnancy." You may also notice some darkening of your nipples, freckles, scars, underarms, inner thighs, and vulva. That darkened line running from your belly button to your pubic bone is called the linea nigra, or "dark line."

These darkened spots will probably fade shortly after delivery. In the meantime, protect yourself from the sun, which intensifies the pigment changes. Cover up, wear a brimmed hat, and use sunscreen when you're outdoors. And if you're self-conscious about your "mask," a little concealing makeup can work wonders.

Decision Guide: Naming your baby

For many couples, settling on a name for their baby is a lot of fun. For others, it's a tortuous process of negotiation. Either way, it's an important decision because you're choosing something that will last a lifetime (unless your little one decides to rename herself along the way). Here are some factors to consider when you're deciding on a name:

Sound and compatibility How your baby's name sounds when it's said aloud is one of the most essential things to think about. Is it melodious? Harsh? Does it go well with your last name? One thing to avoid: Choosing a first name that ends in the same sound as the beginning of your last name.

Uniqueness An unusual name has the advantage of making your child stand out from the crowd. On the other hand, a name no one has heard of and few can pronounce can bring attention your child might rather avoid. Spelling variations can help make a name unique, but choosing a name with numerous spellings can cause confusion in your child's life for years to come.

Relatives and friends Many parents choose to name their babies after a grandparent, another relative, or a close friend. Don't want too many Michaels in your house? Look way back in your family tree for hidden treasures. And if you're worried about hurt feelings, consider a first name from one side of the family and a middle name from the other. According to a BabyCenter survey, middle names are a must for most parents; 98 percent give their child a middle name, with 7 percent of those parents giving their child two or more middle names.

Ancestry and heritage Your child's heritage is an essential part of who she is, and you may want her name to reflect that. Skim history books focusing on your family's country of origin to find appropriate possibilities.

Meaning No one is likely to treat your daughter Ingrid differently because her name means "hero's daughter," but the derivation of your baby's name is something you may want to think about. Use BabyCenter's Baby Name tool to learn the meaning of over 5,000 names.

Initials and nicknames People, especially kids, can be cruel when it comes to nicknames, so try to anticipate any potentially embarrassing ones. Consider your child's initials as well, so you don't inadvertently saddle her with a doozy like Z.I.T. or P.E.E.

One of the best tests for a baby name is to yell it out loud, preferably at a playground. If you feel uncomfortable saying the name in that setting, it might not be the best choice.

• Many people going through pregnancy like to refer to their growing baby by name — or nickname. What about you?

This Week's Activity

Start your childcare search. It may seem early to you, but the best centers often have long waiting lists and it's easier to go on tours now than when you have an infant in tow. You have many options, so review the pluses and minuses of daycare centers, nanny care, home daycare, and relative care. Put your name on a few lists even if you aren't sure what you'll do. When the time comes, you may be grateful for the options.

Your pregnancy: 20 weeks

How your baby's growing:

Your baby weighs about 10 1/2 ounces now. He's also around 6 1/2 inches long from head to bottom and about 10 inches from head to heel — the length of a banana. (For the first 20 weeks, when a baby's legs are curled up against his torso and hard to measure, measurements are taken from the top of his head to his bottom — the "crown to rump" measurement. After 20 weeks, he's measured from head to toe.)

He's swallowing more these days, which is good practice for his digestive system. He's also producing meconium, a black, sticky by-product of digestion. This gooey substance will accumulate in his bowels, and you'll see it in his first soiled diaper (some babies pass meconium in the womb or during delivery).

Congratulations! You've hit the halfway mark in your pregnancy. The top of your uterus is about level with your belly button, and you've likely gained around 10 pounds. Expect to gain another pound or so each week from now on. (If you started your pregnancy underweight, you may need to gain a bit more; if you were overweight, perhaps a bit less.) Make sure you're getting enough iron, a mineral that's used primarily to make hemoglobin (the part of your red blood cells that carries oxygen). During pregnancy, your body needs more iron to keep up with your expanding blood volume, as well as for your growing baby and the placenta. Red meat is one of the best sources of iron for pregnant women. Poultry (especially the dark meat) and shellfish also contain iron. Some common non-meat sources of iron include legumes, soy-based products, spinach, prune juice, raisins, and iron-fortified cereals.

If you haven't already signed up for a childbirth education class, you may want to look into one, especially if you're a first-timer. A structured class will help prepare you and your partner for the rigors of labor and delivery. Most hospitals and birth centers offer classes, either as weekly meetings or as a single intensive, one-day session. Many communities have independent instructors as well. Ask your friends, family members, or caregiver for recommendations.

Take an extra pillow to bed tonight "I found it so much easier to sleep on my side when I hugged a pillow and wrapped my legs around it. In fact, two years after the birth of my child, it's still my favorite way to fall asleep." — Clara

Surprising Facts: Getting a good night's rest

It may become more difficult to sleep through the night as your pregnancy progresses, thanks to some obvious and not-so-obvious changes taking place in your body. You may be surprised to find that:

• You start snoring for the first time in your life, thanks in part to more estrogen, which contributes to swelling of the mucous membranes that line the nose and may even cause you to make more mucus. What to do: Sleep on your side and elevate your head slightly.

Heartburn and indigestion can make it extra uncomfortable to lie down in bed. What to do: Avoid foods that trigger your heartburn, give yourself two to three hours to digest a meal before going to bed, and try sleeping semi-upright in a comfy recliner or propped up with extra pillows under your upper body.

Leg cramps jar you out of a deep sleep. What to do: Ease the cramp by straightening your leg, heel first and gently flexing your toes back toward your shins, or walk around for a few minutes.

• You toss and turn all night trying to find a comfortable sleeping position. What to do: Lie on your side with your knees bent and a pillow between your legs. For extra comfort and support, arrange other pillows under your belly and behind your back. Or try using a contoured maternity body pillow.

• You become hot and sweaty in the middle of the night. It's common for pregnant women to feel a little warmer than usual thanks to shifts in your metabolism, hormones, and weight. What to do: Keep your bedroom cool and strip down to the bare essentials. Keep slippers and a snuggly bathrobe handy for those nighttime trips to the bathroom.

• Getting out of bed is harder than ever! What to do: Roll over onto your side so you're facing the edge of the bed. Dangle your legs over the side and use your arms to push yourself into a sitting position. Plant your feet squarely on the floor and then stand up.

Wear sleepwear made of a natural, breathable fiber like cotton. Avoid synthetics, which trap moisture next to your skin and can leave you damp and chilled.

• Sometimes even when you're exhausted, you just can't sleep. So do you toss and turn waiting for sleep to catch up with you — or do something else in the meantime? Take our poll.

This Week's Activity:

Treat yourself to something nice. You've made it to the halfway mark in your pregnancy, so celebrate with a little indulgence. Need some ideas?

• For your comfort, try scented candles, a new nightgown or pajamas, or a prenatal massage.

• For a keepsake, splurge on professional pictures of your pregnant self, or a beautiful frame for your baby's first picture after birth. (In the meantime, you can use an ultrasound picture!)

• To feel like a hot momma, buy yourself a piece of clothing that makes you feel really sexy or get a free makeover at a department store.

Your pregnancy: 21 weeks

How your baby's growing:

Your baby now weighs about three-quarters of a pound and is approximately 10 1/2 inches long — the length of a carrot. You may soon feel like she's practicing martial arts as her initial fluttering movements turn into full-fledged kicks and nudges. You may also discover a pattern to her activity as you get to know her better. In other developments, your baby's eyebrows and lids are present now, and if you're having a girl, her vagina has begun to form as well.

You're probably feeling pretty comfortable these days. You're not too big yet, and the usual discomforts associated with early pregnancy are, for the most part, gone. If you're feeling good, relax and enjoy it while you can — the third trimester may bring with it a new crop of complaints.

That's not to say you won't have some minor glitches to deal with now. For example, increased oil production may contribute to the development (or worsening) of acne. If that's the case, be diligent about washing well with a gentle soap or cleanser twice a day, and make sure that any moisturizer or make-up you use is oil-free. Don't take any oral acne medications — some are very hazardous during pregnancy — or use any topical acne products without first checking with your practitioner.

You're also more prone to varicose veins now. As your pregnancy progresses, there's increasing pressure on the veins in your legs; higher progesterone levels, which may cause the walls of your veins to relax, can make the problem worse. You're more likely to get varicose veins if other family members have them. Also, they tend to get worse with each successive pregnancy and as you age. To help prevent or minimize varicose veins, exercise daily, prop up your feet and legs whenever possible, sleep on your left side, and wear maternity support hose.

You may also notice so-called spider veins (a group of tiny blood vessels near the surface of your skin), particularly on your ankles, legs, or face. They may have a spider- or sunburst-like pattern with little branches radiating out from the center, they may look like the branches of a tree, or they may be a group of separate thin lines with no particular pattern. Though they may be a bit unsightly, spider veins don't cause discomfort and usually disappear after delivery.

Hit the garage sales "I saved a ton of money on baby gear, nursery furniture, and toys by going to garage sales a few months before my baby was due. Many of the items I found were as good as new!" — Becca

Your pregnancy: 22 weeks

How your baby's growing:

At 11 inches (the length of a spaghetti squash) and almost 1 pound, your baby is starting to look like a miniature newborn. His lips, eyelids, and eyebrows are becoming more distinct, and he's even developing tiny tooth buds beneath his gums. His eyes have formed, but his irises (the colored part of the eye) still lack pigment. If you could see inside your womb, you'd be able to spot the fine hair (lanugo) that covers his body and the deep wrinkles on his skin, which he'll sport until he adds a padding of fat to fill them in. Inside his belly, his pancreas — essential for the production of some important hormones — is developing steadily.

At this point, you may find your belly becoming a hand magnet. It's perfectly okay to tell folks who touch your tummy that you'd rather they didn't. And if people are telling you that you look smaller or bigger than you should at this point, remember that each woman grows — and shows — at her own rate. What's important is that you see your practitioner for regular visits so she can make sure your baby's growth is on track.

You may start to notice stretch marks on your abdomen as it expands to accommodate your growing baby. At least half of all pregnant women will develop stretch marks by the time they give birth. These small streaks of differently textured skin can range from pink to dark brown (depending on your skin color). Although they most commonly appear on your tummy, stretch marks may also show up on your buttocks, thighs, hips, and breasts. There's no proof that lotion helps prevent stretch marks, but keeping your skin moisturized may help with any itching.

Surprising Facts: Body changes beyond your belly

You expected your belly to grow — and perhaps your breasts, too — but the following physical changes may take you by surprise. As with many pregnancy changes, hormones play a role in most of these alterations in your looks.

Thicker, more lustrous hair You're not actually growing more hair, just losing less than normal. During pregnancy, your body sheds hair much more slowly than it did before. What to do: If thicker hair is a boon for you, enjoy it. If it's making your mane more unruly than ever, ask your stylist to do some thinning at your next cut. These changes won't last forever. After your baby's born, you'll start to lose this excess hair, sometimes in clumps.

Increased body hair Sex hormones known as androgens can cause new hair to sprout on your chin, upper lip, jaw, and cheeks. Stray hairs can also pop up on your belly, arms, legs, and back. What to do: Tweezing, waxing, and shaving are all safe ways to manage these temporary changes.

Faster-growing fingernails Your fingernails may grow more quickly than usual, and you may notice changes in texture. Some women's nails get harder, while others' get softer or more brittle. What to do: Protect your nails by wearing rubber gloves when you're cleaning, and using moisturizer on them if they're brittle.

Skin changes Some pregnant women report that their skin has never looked better. If that's you, enjoy the proverbial "glow." Others find the hormones of pregnancy aggravate skin conditions such as acne. What to do: Wash twice a day with a gentle soap or cleanser, and make sure that any moisturizer or makeup you use is oil-free.

Stretch marks As your belly expands to accommodate your growing baby, you may get tiny tears in the supportive tissue that lies just beneath your skin, resulting in striations of varying color. These marks will begin to fade and become considerably less noticeable about six to 12 months after you give birth. There's not much you can do besides trying not to gain more than the recommended amount of weight. Heredity is responsible for the natural elasticity of your skin and plays a role in determining who will end up with stretch marks.

Skin discolorations Increased melanin can cause splotchy patches of darkened skin on your face. These pigment changes may become intensified if you spend time in the sun. What to do: Protect your face by using a sunblock that offers both UVA and UVB protection with an SPF of 30 or higher, wearing a hat with a brim, and avoiding the sun during peak hours of the day (10 a.m. to 2 p.m.).

Larger and darker nipples and areolas You may find that your nipples and the pigmented area around them (the areolas) are getting bigger and darker. The little bumps on your areolas, known as Montgomery's tubercles, may also be more pronounced. These bumps are oil-producing glands that help fight off bacteria and lubricate the skin. Some women also notice more pronounced veins in their breasts. What to do: Nothing!

Larger feet Your feet may go up half a shoe size or more. Lax ligaments may make your feet spread a bit — permanently. Swelling can make your shoes feel tight as well, although it will go away after delivery. What to do: Buy comfortable shoes to accommodate your growing feet.

This Week's Activity:

Check out your rings. It's common to have some swelling in your fingers as your pregnancy progresses. If your rings are feeling the least bit snug, do yourself a favor and take them off now before it's too late (or at least keep an eye on them). If you can't bear to be separated from your wedding band or another important ring when you can no longer sport it on your finger, loop it on a chain and wear it close to your heart.

How your baby's growing:

Turn on the radio and sway to the music. With her sense of movement well developed by now, your baby can feel you dance. And now that she's more than 11 inches long and weighs just over a pound (about as much as a large mango), you may be able to see her squirm underneath your clothes. Blood vessels in her lungs are developing to prepare for breathing, and the sounds that your baby's increasingly keen ears pick up are preparing her for entry into the outside world. Loud noises that become familiar now — such as your dog barking or the roar of the vacuum cleaner — probably won't faze her when she hears them outside the womb.

You may notice that your ankles and feet start to swell a bit in the coming weeks or months, especially at the end of the day or during the heat of summer. Sluggish circulation in your legs — coupled with changes in your blood chemistry that may cause some water retention — may result in swelling, also known as edema. Your body will get rid of the extra fluid after you have your baby, which is why you'll pee frequently and sweat a lot for a few days after delivery. In the meantime, lie on your left side or put your feet up when you can, stretch out your legs when you sit, and avoid sitting — or standing — in one place for long periods. Also, try to exercise regularly to increase circulation, and wear support stockings (put them on first thing in the morning) and roomy, comfortable shoes. You may be tempted to skimp on liquids to combat swelling, but you need to drink plenty of water because staying hydrated actually helps prevent fluid retention. While a certain amount of edema in your lower extremities is normal during pregnancy, excessive swelling may be a sign of a serious condition called preeclampsia. Be sure to call your midwife or doctor if you have severe or sudden swelling of your feet or ankles, more than slight swelling of your hands, swelling in your face, or puffiness around your eyes.

Decision Guide: Should you bank your baby's cord blood?

Cord blood banking is a procedure in which the blood left in your baby's umbilical cord and placenta after birth is collected, frozen, and stored for future medical use. Cord blood is prized because it's a rich source of stem cells — the building blocks of the blood and immune system. Stem cells have the ability to differentiate into other tissues, and cord blood can be used to treat a host of diseases, including leukemia and sickle cell anemia. Only you can decide whether banking your baby's cord blood is right for your family. Factors to consider:

Cord blood research is showing promising preliminary results.

Studies are under way around the world, and many researchers are optimistic about the future. For instance, cord blood researchers believe that one day some adult cancer patients may benefit from their own cord blood stem cells that were harvested at birth. The hope is that stem cells could be used to treat cancers that aren't genetically based.

In light of recent animal experiments, many researchers also believe that cord blood will eventually be used to treat diabetes, spinal cord injuries, heart failure, stroke, and serious neurological diseases.

However, many experts caution parents to take such studies (especially those conducted on animals) with a grain of salt, because it's difficult to predict when, if ever, these treatments will become available for humans. The March of Dimes, a nonprofit organization dedicated to improving the health of babies, sums it up this way: "The use of umbilical cord blood stem cells for transplantation treatment holds exciting promise, but this area of medical science is still largely investigational."

It's expensive.

Private cord blood banks usually charge an enrollment and collection fee of about $2,000 or so, plus annual storage fees around $125.

Chances are that your baby cannot be treated with his own cord blood.

If your child has or develops an illness with a genetic basis — which is often the case with conditions that could benefit from a cord blood transplant — his cord blood contains the genetic instructions for that disease, so it's not a suitable treatment. Most banked cord blood is currently used to treat siblings.

You probably have a better chance of finding a stem cell match in the public cord blood system than in your own family.

The chance of an exact tissue match between two siblings is only about 25 percent, according to Dennis Confer, chief medical officer for the National Marrow Donor Program, a nonprofit organization that maintains the largest public listing of umbilical cord blood units available for transplantation in the United States. In contrast, the chance of finding a cord blood match in the nation's public banks is 75 percent, he says.

Doctors aren't ready to universally recommend banking your baby's cord blood.

The American Academy of Pediatrics and some other experts have expressed reservations about private cord blood banking for the general public because they believe the chances a family will ever need the blood are slim and because they support a public cord blood donation system (similar to blood banks). However, cord blood banking is encouraged when there's an immediate family member who's already been diagnosed with a condition that may be treated with cord blood transplantation. (In this situation, you may be eligible for a special cord blood banking program called "The Sibling Connection," in which your baby's cord blood will be collected, processed, and stored for five years at no cost to you. Call 866-861-8435 for more information.)

If your child belongs to a minority group, private storage may be of more value to you.

According to July 2003 figures, a Caucasian patient has an 88 percent chance of finding a matching donor through the registry of the National Marrow Donor Program, while an African American's chances were significantly lower at 58

Your pregnancy: 24 weeks

How your baby's growing:

Your baby's growing steadily, having gained about 4 ounces since last week. That puts him at just over a pound. Since he's almost a foot long (picture an ear of corn), he cuts a pretty lean figure at this point, but his body is filling out proportionally and he'll soon start to plump up. His brain is also growing quickly now, and his taste buds are continuing to develop. His lungs are developing "branches" of the respiratory "tree" as well as cells that produce surfactant, a substance that will help his air sacs inflate once he hits the outside world. His skin is still thin and translucent, but that will start to change soon.

In the past few weeks, the top of your uterus has risen above your belly button and is now about the size of a soccer ball.

Most women have a glucose screening test (also called a glucose challenge test or GCT) between now and 28 weeks. This test checks for gestational diabetes, a pregnancy-related high-blood-sugar condition. Untreated diabetes increases your risk of having a difficult vaginal delivery or needing a cesarean section because it causes your baby to grow too large, especially in his upper body. It also raises your baby's odds for other complications like low blood sugar right after birth. A positive result on your GCT doesn't mean you have gestational diabetes, but it does mean that you'll need to take the glucose tolerance test (GTT) to find out for sure.

Finally, if you don't already know how to spot the signs of preterm labor, now's the time to learn. Contact your caregiver immediately if you notice any of the signs mentioned below.

How your baby's growing

Head to heels, your baby now measures about 13 1/2 inches. Her weight — a pound and a half — isn't much more than an average rutabaga, but she's beginning to exchange her long, lean look for some baby fat. As she does, her wrinkled skin will begin to smooth out and she'll start to look more and more like a newborn. She's also growing more hair — and if you could see it, you'd now be able to discern its color and texture.

Your baby's not the only one with more hair — your locks may look more full and lustrous than ever. It's not that you're growing more hair, but thanks to hormonal changes, the hair that you'd normally shed is sticking around longer than usual. Enjoy the fullness while you can — the extra hair will fall out after you give birth.

You may also notice that you can't move around as gracefully as before. Unless your caregiver has advised you otherwise, it's fine to continue to exercise, but follow a few safety rules: Don't work out when you're feeling overly tired and stop if you feel any pain, dizziness, or shortness of breath. Don't lie flat on your back and avoid contact sports as well as any exercise where you're apt to lose your balance. Be sure to drink plenty of water, and make time for both warm-up and cool-down periods.

When you have your glucose-screening test at 24 to 28 weeks, a second tube of blood may be taken at the same time to check for anemia. If blood tests show that you have iron-deficiency anemia (the most common type of anemia), your caregiver will probably recommend that you take an iron supplement.

Have you started thinking about baby names yet? Choosing a name is an important decision, but it should be a fun one, too. You may want to consider family history (Great Grandpa Zeb), favorite locations (Venice, where you honeymooned), or cherished literary or film characters (Greta, Meg, or Atticus, for example). Check out a couple of baby-name books to help you brainstorm, too.

How your baby's growing:

The network of nerves in your baby's ears is better developed and more sensitive than before. He may now be able to hear both your voice and your partner's as you chat with each other. He's inhaling and exhaling small amounts of amniotic fluid, which is essential for the development of his lungs. These so-called breathing movements are also good practice for when he's born and takes that first gulp of air. And he's continuing to put on baby fat. He now weighs about a pound and two-thirds and measures 14 inches (an English hothouse cucumber) from head to heel. If you're having a boy, his testicles are beginning to descend into his scrotum — a trip that will take about two to three days.

Are you rushing around trying to get to childbirth classes and prepare your baby's room while still taking care of all your other daily tasks? Make sure that you also continue to eat well and get plenty of rest. Around this time, your blood pressure may be increasing slightly, although it's probably still lower than it was before you got pregnant. (Typically, blood pressure falls toward the end of the first trimester, and it tends to reach a low at about 22 to 24 weeks.)

Preeclampsia — a serious disorder characterized by high blood pressure and protein in your urine — most often shows up after 37 weeks, but it can happen earlier so it's important to be aware of the warning signs of this condition. Call your caregiver if you have swelling in your face or puffiness around your eyes, more than slight swelling of your hands, excessive or sudden swelling of your feet or ankles, or rapid weight gain (more than 4 pounds in a week). With more severe preeclampsia, you may experience other symptoms. Let your caregiver know immediately if you have a severe or persistent headache, vision changes (including double or blurred vision, seeing spots or flashing lights, sensitivity to light, or temporary loss of vision), intense pain or tenderness in your upper abdomen, or vomiting.

If your lower back seems a little achy lately, you can thank both your growing uterus — which shifts your center of gravity, stretches out and weakens your abdominal muscles, and may be pressing on a nerve — as well as hormonal changes that loosen your joints and ligaments. Plus, the extra weight you're carrying means more work for your muscles and increased stress on your joints, which is why you may feel worse at the end of the day. Walking, standing, or sitting for long periods, as well as bending and lifting can all put a strain on your back. A warm bath or hot compress might bring relief. (Some women, though, find cool compresses more comforting.) Try to maintain good posture during the day, avoid activities that require bending and twisting at the same time, take frequent breaks when sitting or standing, and sleep on your side with one or both knees bent with a pillow between your legs, using another pillow (or wedge) to support your abdomen.

Decision Guide: Should you create a birth plan?

Writing a birth plan can give you an opportunity to think about — and discuss with your partner and caregiver — how you'd ideally like your delivery to be handled. The process of creating a birth plan can be a terrific way to learn more about labor and your own preferences for care. But keep in mind that labor is inherently unpredictable, and you'll need to stay flexible in case things come up that require you and your birth team to veer from the plan.

So is it worth doing?

If you use the birth plan as an educational tool to learn more about your options during labor and delivery and as a point of departure for talking to your caregiver and communicating your wishes, you can't go wrong.

In a recent BabyCenter poll about birth plans, 54 percent of those who responded said their plan was irrelevant once actual labor started. "My birth plan pretty much went out the window once I got to the hospital. But not sticking to the plan didn't take away from my birth experience at all," said one respondent. On the other hand, 46 percent said their birth plans did help them create the birth experience they wanted. Said one new mom: "I was amazed. My midwife and the nurses followed my birth plan like an instruction manual. I was so worried because I had heard all these awful stories about how the hospital staff really doesn't care about birth plans. I got everything I wanted out of my daughter's birth."

If you decide you want to try making a birth plan, it can be as long or short as you like. Some women simply write down their birth philosophy and a general sense of how they'd like things to go. For instance, "I'd like to have as natural a birth as possible. Please don't offer me pain relief medication or do any interventions unless necessary." Or "I'd like my labor to be relatively pain-free and want an epidural as early as possible."

Some issues to consider when creating a birth plan:

• Do you want a drug-free labor or are you banking on an epidural? If you're not sure, it's okay to make a note of that.

• Do you want your delivery to be a private affair (just the attending medical team and your partner)? Would you like other family members or friends in the room for support? Is it okay if medical students or residents are present during your birth?

• Do you want a mirror brought in so you can see your baby crowning?

• Would you like to have the room as quiet as possible? Have special music playing? The lights dimmed? A video camera rolling?

• After your baby's born, do you want your partner to cut the cord? Would you or your partner like to stay with your baby during any procedures or exams?

• Do you plan to breastfeed?

• Do you want your baby to stay with you around-the-clock?

• Are you willing to pay extra for a private room if one's available?

For a detailed look at all the questions to consider, see BabyCenter's online Birth Plan tool.

This Week's Activity:

Discuss some personal issues. Would you like to have your son circumcised? If so, do you want it done in the hospital? Will you have a religious ceremony after your baby's born? Would you like to stay home with your baby full- or part-time? These are just a few of the big decisions you and your partner should discuss now. Even if you think you both agree, it's best to share your opinions openly to avoid misunderstandings and hurt feelings.

Your pregnancy: 27 weeks

How your baby's growing:

This week, your baby weighs almost 2 pounds (like a head of cauliflower) and is about 14 1/2 inches long with her legs extended. She's sleeping and waking at regular intervals, opening and closing her eyes, and perhaps even sucking her fingers. With more brain tissue developing, your baby's brain is very active now. While her lungs are still immature, they would be capable of functioning — with a lot of medical help — if she were to be born now. Chalk up any tiny rhythmic movements you may be feeling to a case of baby hiccups, which may be common from now on. Each episode usually lasts only a few moments, and they don't bother her, so just relax and enjoy the tickle.

The second trimester is drawing to a close, but as your body gears up for the final lap, you may start noticing some new symptoms. Along with an aching back, for example, you may find that your leg muscles cramp up now and then. They're carrying extra weight, after all, and your expanding uterus is putting pressure on the veins that return blood from your legs to your heart as well as on the nerves leading from your trunk to your legs. Unfortunately, the cramps may get worse as your pregnancy progresses. Leg cramps are more common at night but can also happen during the day. When a cramp strikes, stretching the calf muscle should give you some relief. Straighten your leg and then gently flex your toes back toward your shin. Walking for a few minutes or massaging your calf sometimes helps, too.

It may be the furthest thing from your mind right now, but it's not too soon to think about family planning. You'll want to have made some decisions about postpartum birth control before your baby arrives. If you're considering a tubal ligation, be aware that most states require you to sign a consent form at least 30 days beforehand. So if you'd like the option of having the surgery during your postpartum hospital stay, don't wait too much longer to discuss it with your caregiver. (You can still change your mind later.)

Surprising Facts: Symptoms you should never ignore

So many aches, pains, and strange feelings arise during pregnancy that it can be hard to decide what's normal and what warrants a call to your doctor or midwife. To complicate matters further, some symptoms may be more or less urgent depending on your particular situation or health history and on how far along you are in your pregnancy. Here's a rundown of symptoms that could be a sign of a problem. If you have any of these complaints, call your doctor or midwife immediately:

Before you reach 37 weeks:

• Pelvic pressure (a feeling that your baby is pushing down), lower back pain (especially if it's a new problem for you), menstrual-like cramping or abdominal pain, or more than four contractions in an hour (even if they don't hurt)

• An increase in vaginal discharge or a change in the type of discharge — if it becomes watery, mucus-like, or bloody (even if it's only pink or blood-tinged)

At any time:

• Your baby is moving or kicking less than usual

• Severe or persistent abdominal pain or tenderness

• Vaginal bleeding or spotting, or watery discharge

• Pain or burning when you urinate, or little or no urination

• Severe or persistent vomiting, or any vomiting accompanied by pain or fever

• Chills or a fever of 100 degrees Fahrenheit or higher

• Blurred or double vision, or seeing spots or "floaters"

• A severe or persistent headache, or any headache accompanied by blurred vision, slurred speech, or numbness

• Any swelling in your face or puffiness around your eyes, anything more than mild swelling in your fingers or hands, or severe or sudden swelling in your legs, feet, or ankles, or a rapid weight gain (more than 4 pounds in a week)

• Severe or persistent leg or calf pain that doesn't ease up when you flex your ankle and point your toes toward your nose, or one leg significantly more swollen than the other

• Trauma to your abdomen

• Fainting, frequent dizziness, rapid heartbeat, or palpitations

• Difficulty breathing, coughing up blood, or chest pain

• Severe constipation accompanied by abdominal pain or severe diarrhea that lasts more than 24 hours

• Persistent intense itching all over

• Any health problem that you'd ordinarily call your practitioner about, even if it's not pregnancy-related (like worsening asthma or a cold that gets worse rather than better)

Even if you don't see your symptom on the list above, trust your instincts and call your caregiver whenever you have a concern about your pregnancy. If there's a problem, you'll get help right away. If nothing's wrong, you'll be reassured.

This Week's Activity:

Sign up for a breastfeeding class. If you are a first-time mom and planning to breastfeed your baby, it's a good idea to take a breastfeeding class. Ask your caregiver or childbirth education teacher where you can take one. Or call La Leche League. It can help you locate breastfeeding resources in your area.
