My 6yr old son is a aspie, has always had violent outbursts. When he started pre-school, the other mums thought I had a violent husband. Then they found out who was hurting me & couldn't believe that a 2yr old could cause such injuries. It's mainly me & his younger brother that get most of it. U need 2 keep a diary 2 help u figure out wot triggers him off. Have solid rules & routines 4 him. This helps him know where he's at. I find distracting my son helps if he's only 1/2 Mad. Good luck. X
