It is one of the most universal of parenting fears, a necessary evil we cannot shield our kids from for long because we know they will have to live and work in this world as adults. I am talking, of course, about the internet. From the time they’re toddling around and trying to pry our own phones out of our hands, to their teenage days, when much of their social life happens online, we’ve got precious few years to teach our kids how to navigate the online world as safely as possible.

For help on how to do that, I spoke with Devorah Heitner, author of Screenwise: Helping Kids Thrive (and Survive) in Their Digital World and the upcoming book Growing Up in Public: Coming of Age in a Digital World. I’ll also provide some additional resources for each age group along the way.
