I am a mom with a son who has special needs too, Down syndrome in fact. It's great that your son is doing so well! We've been using the free trial for months, and he loves it. I usually skip the games because it seems that he just smacks the ipad randomly, but maybe I should do them for him?
Anyway, thanks for the encouragement! I really need to look into getting the full version.

My son is 18mo, so our boys are kinda close in age.
