Thanks for sharing so much of your story. Does he sit and listen for any activities? My DD used to be unable to sit quitely for storytime, circle time, etc. but now she sits quite still and quietly for those thing which gives me more hope. She is particularly good if she is surrounded by more contained, older kids, but feeds on wild energy if it is around. Loud music, lights, younger crazy kids, etc. while get her so rowdy. In a school environment, where things are more sedate, I am hoping she will be OK but still have my doubts! I have heard of brushing and wonder if she would like it or not. My DD constantly talks and sings and I don't know if she likes stimulation in her mouth or it has to do with her being so verbal and imaginative (probably both). Thanks again for sharing your experience. I am encouraged that you think it helped. Good luck.
