I forgot to mention that Jonathan has discovered faces. He'll pick them out of a room full of things to look at...tonight at VA girls I noticed that he was switching between looking at my face and at Jessica's. He definitely knows that faces are for looking at.
He also likes looking at himself in the mirror. I'm not sure what he thinks it is, except that I guess he recognizes it as a face, but he does really like it. I let him look at himself every morning after he has his sponge bath, and always say "There is Mommy, and that is Jonathan" when I see his eyes focus on one of us. I wonder when self-knowledge comes, enough that he could understand such a concept?
