No Code, I think I forgot (or never knew) that your oldest had Asperger's. My oldest, who will graduate from Berkeley this year, is very mildly on the Asperger's spectrum as well.
Are you so sure this other county won't have adequate services? Are there any services that would be better than an extra 2 hours a day with dad?
(And btw, make sure your child has an adequate vitamin D level, and no evidence of gluten or dairy sensitivity.)
