Hi Mickey Mom,
I don't know what services are provided in your state, but I would start calling different agencies in your area to see if your child may get some medical assistance from the State. When my son was diagnosed with Autism, he became eligible for a Medical Access card. I had to apply for this card at the Department of Public Welfare office.
Another option you may want to try, is calling your local school district. Our local district here provides a special class for young Autistic children called a Verbal Behavior class. My son started almost a year ago (at 3 1/2 years old) and has progressed wonderfully. In this class, he also receives speech therapy and occupational therapy.
Hope this helps. Best of luck to you!
P.S. By the way, thank you for your post on the Main Message Board. I didn't know this board existed until I read your message.
