The name thing is kind of odd. It isn't from lack of interaction with the other kids. He remembers details about them. Santa came to the classroom during the party and the kids went up to tell him what they wanted. While they were waiting the girl next to my son leaned over and said "I can't remember what I want. I don't know what to say". He said "You want a kitten. One with long white fur. That is what you said when we talked about this in class."

So he remembers faces and details about them. "The boy that swallowed his tooth" "The boy that gets to watch scarey movies" "The girl that is allergic to milk"

We will figure out something.

I know we need to focus on strengths and not just weaknesses. I know he will get through elementary and be fine. It is just sad that what constitutes "school" for young 2E kids is mostly focused on weaknesses.
