My 5 year old son is in reception year at school he has a statement with the school as he needs the extra help with school work. My problem is he hits other kids at school and does nt show any emotion of doing it, he knows hitting is naughty but when you tell him of for doing so he has no emotion with his face expression that he has done something wrong,the school has run out of discipline ideas and so have i, I dont no why he does things like this it not as if I have raised him by smacking him or he knows this behaviour im really worried. Time outs dont work any more
