sorry for typo's my keyboard is sticking
Nowadays many folks want to put a label on all child behavior . Does he see any of this at home does anyone yell or hit him as it can be learned behavior, has he any older siblings ?What is he doing when you tell him to go to bed and he wont ,is he on the PC or watching TV ..if he is you give him a 10 min warning about bed and after the 10 mins switch it off.Do not get into arguments about say nothing.Who is it he is hitting when you say he hits 'people' all the time ?
