I work with a Lady who has experience (her DD1) with the autistic world. She has learned great insights into the perceptions and thought patterns of the autistic mind. I just sent her an email. I'll pass on whatever thoughts my friend has. It would probably help to find out where this child's gift lies for he will be drawn to that interest (my 2 cents).
