Hi Sherri,
Since me and another Sherri on this board freqently exchange posts, I just had to say hi and offer you any support you may need. I am not in Arkansa, but would advise that you check with your local government agencies for special education, child find, public schools, and disabililty law centers. Since I am not from your area, I can't give you any specifics, but this is how I got started when my son was your son's age. I hope you can find some resources that will help you and your son. Also check on the internet for autism resources, there is a site on there that goes by state. If I can find it, I will write you again and give you the address. I hope to talk with you soon.
Sherry
