Kitsune,
Your baby very sticky type? I read that this is the time when baby actually starts to understand what we say. So we should start to talk more to baby, like telling him this is a book, this is tv, a tree, a car, etc etc. Baby still can't talk now, but the motherboard+memory card+hard-disk started to function already.
My baby still hasn't develop stranger anxiety. He loves to follow anyone who is willing to play with him. Except at night before bedtime, he must look for mummy.
