Oh wow, I remember DD9 doing that I think when she was 3 or 4. Some stuff she had fun with but other times like circle time, the teacher had to let her do her own thing and when it was her time to chime in she proved she was listening every time and did well.

I wish I had some advice but it sounds like he's doing much better now. Keep it up mom!

The impossible is just something that hasn't happened yet.
