You ask about the parents. I attended a meeting for a child with learning disabilities. The mother made the comment that they have several children ranging in age from mid-20s to this one at 12. The one that is 17 has autism. They didn't notice the autism until the kid was 10!

We had parent-teacher night and the family of only one student showed up. The school offers a free dress-down day to kids whose parents attend PTO or parent-teacher conferences.

As I understand it there is no help there.
