WELCOME!! I'm in Austin, and I have a 6 year old who was just diagnosed with Asperger's about 6 wks ago. Homeschooling is the only answer for us. Academically, physically, and mentally, he's all over the place - very adultlike, but very childlike. He doesn't do well at all in a normal environment.
Jump right in and ask all the questions you want. If you haven't already, you should take a look at this site:
