Hey Collinsmom...I have an idea. Give him something that he CAN bite when he wants to bite. My son used to get so mad when he was around 5 I made him go hit his pillow as hard as he could as much as wanted to. Eventually he got tired of that and just learned to control his temper. Now he's 20 and a pretty laid back kid. I think there's something about little boys they need to vent physically. Well, maybe girls do too. I'll think about my daughter later. Maybe Collin could have a pillow or a blanket or something he could carry-with to bite.
