My DS is 4 next week - he's been going to nursey for a year and goes to proper school next september. he just hits/pushes all the other children - you can't take you eyes off him. he knows it's wrong but does it any way. he can't control his temper and get very very cross with whoever is there. he is only like this in big groups - with one or two others children he is usually ok. is there anything wrong with him. we are expecting baby number 2 in may and i'm just in tears all the time about this. i even had to take him home from a party last week end cos he just couldn't stop pushing the others kids - what can i do???
