My DS was in preschool last year and was quite difficult, he didn't listen to the teachers and would hit the other children. He started primary school yesterday and when I took him in again today the teacher took me aside and told me that he had a bad day yesterday. He didn't do anything he was asked and hit 4 children, headbutting one (I don't even know where he's ever seen a headbutting before and was in shock when she told me!!). She said this couldn't happen at all which I obviously agreed with and said I'd talk to him.
The problem is I am really struggling with what to do about this, he's an only child so I've not encountered this before and at home his behaviour is really great, we're always complimented on it. He does what he is asked at home and if he does hit/talk back/refuse something I ask I send him for a 'time out', and if he continues to hit after that then time out again and he isn't allowed a privilege.
I don't smack him, I don't let him watch anything he shouldn't on tv, I make sure he eats healthily and is in bed for 7pm. I don't know how to stop the behaviour at school, when he was at preschool and it happened I'd take away favourite toys and privileges (like tv, going to softplay etc) and if he behaved he'd get a lot of praise but tbh nothing I done stopped the bad behaviour, where am I going wrong? - I'd appreciate any advice or someone who's had the same experience what did the primary school do, do they expel children so young?
