Oh gosh! That is a lot to take care of! I don't know if your son likes to watch TV, but he might really like Doctor Who
But I know that sometimes kids with Autism spectrum can be sensitive to certain kinds of shows/movies/books. My pastor's daughter has high-functioning Asberger's (on the autism spectrum, plus OCD, anxiety disorder, etc.) and she is sensitive to violence, evil people/creatures, or even suspenseful situations, not only in movies and TV, but also in books. Doctor Who is suspenseful, moderately scary, and does include violence like things blowing up, or violent aliens.
