Well, I just have a short true story for you. A hs family I know had their son assessed by a speech therapist. The ST was very insistent that the child needed to be in school so he could LEARN. He never went to school, the family was never investigated by DHS, and they had not filed a NOI btw, and they are doing fine.
So I hope the same thing happens for you and that your son is allowed to live his life and develop in the way he wants/needs to.
