SCHOOL!!!
Leavesman, Cristina, i would worry so much about infractions and lack of anything really being done for him--i'd homeschool! it sounds awful! and if any of the other students have hitting or biting issues, your little guy's in trouble. sorry, I know you're looking for constructive advice, but, i don't even think a great IEP would save your situation, esp. when you say there's more issues than you've shared with us so far. i really would pull him out in your situation, and just have him peer play with your twins. sigh. hope it works out for you. katm0mdu
