my 3yr old is being bullied by my friends son of the same age. he use to be a happy go lucky chap but recently turned into a little terror. He would shamelessly hit, push, punch and even bite my Lo. I've tried telling him off and tell him to say sorry but he refuses point blank. he does this in front of his mum; she tells him to say sorry but he digs his heels in and refuses and she doesnt push the issue. he is very clever and sly about it and comes and checks what the mums are doing before going back to the play room, 5 seconds later you will hear a howl from the next room. Tonight while giving my LO a bath a noticed bite and scratch marks on LO's back, neck and arms I asked what happened and he said it was the little boy. my lo hates conflict and when he is being bullied by this child he usual removes himself from the situation and plays by himself.
I have no idea how to go about talking to my friend as I'm afraid there will be a fall out. I dont want my lo playing with this child but want lo to know how to stand up to this sort of behaviour. of course I've spoken to lo and have stuck up for lo and told said child off but I also dont like the thought of some child treating lo like this especially that of a close friend. please help.
