While playing with a sibling your child removes a toy from their sibling's hands.  The sibling protests by saying "mine", vocalizes in frustration, and/or becomes angry/upset.  Your child's behavior changes: gives back the toy, becomes upset and/or cries.

Show your child different sounds and the emotions you might have when you hear them. If you hear an ambulance, point to your ear and say "I hear that, that's loud" or if you can say "That sound is scary! I don't like that sound!" By sharing your feelings about sounds, you help to connect language and meaning to what your child hears.
