By 12 months of age, you'll probably see him:
- react to unfamiliar situations or people with shyness or nervousness
- show preference for mom or dad or certain caregivers
- have a favorite toy or spot in the house
- help you help him get dressed by putting out legs or switching arms
- play "peek-a-boo," "pat-a-cake," or other interactive games
Highlight: Peek-a-boo can actually let you teach young children the idea of permanence, which will help a child with separation anxiety to understand that, while you might leave the room (or the house) for a period of time, you will come back. Try variations with toys, hiding them under a blanket and then unveiling them with a dramatic "peek-a-boo!" You can then move on to hide-and-seek-type games where you hide in easy-to-find places and let your toddler find you. As she realizes that you'll always be found, she may become better able to spend time away from you.
