Congratulations. Seriously. That's major work. Most of the adult autistics I know had to figure it out for themselves. There was no support or therapy when I was a kid. We don't get over autism. It is who we are. What we do learn are techniques and skills to deal with the difference between how we see the world and how more neurotypicals see the world; how to advocate for our own needs; and how to ensure that we have the conditions in place that will allow us to reduce stress and over stimulation. Those needs are the for an autistic child like yours and an autistic adult like me with 50+ years of experience. I would recommend the book "The Spark" by Kristine Barnett. What is amazing is her understanding of herself as a parent and educator. I'm a professor of early childhood studies and I'm presently building a multisensory research lab. I'm no expert in child development or autism, per se, though. But what I saw in Kristine's story was that she had the great ability of observation and listening to the needs of her child. She realized that without allowing her child to pursue intrinsic interests and motivations, he would never grow in a social space. I've observed this with autistic children and adults. I think that everyone should focus most on their intrinsic interests and motivations in life. Even John Locke goes on about that in his own ways. But for an autistic it is a matter between being able to function and a life of anger, boredom and frustration. Find out how to stimulate him in ways he wants to be stimulated, and then use that to improve his typical education. He will want to learn to read, write, socialize IF it is tied to things that interest and engage him. Barnett talks about that in her book too, so it is a great start and story of how to look to your child for answers to how to help him. Best of luck!
