Hi, I'm not a doctor but a mom, I don't know how to treat but let me share you this. My son has autism, I was under huge pressure since then. He was always like a piece of wood, my heart was broken. But I wanted to help him. I read a lot of books about autism, I consulted a few doctors and therapist, and I started to train him at home. It was hard, and I did some terrible things, but in 5 years, he has improved huge. If you want to help, learn about the disease, learn about the therapy, try to help. Remeber you're a mom.
