I am a dad to 4 . I have had to take 1 off the children full time due to his behaviour all started off good new school etc . Then out of the blue won't go to school and behaviour is appalling. Made contact with ss who suggested 3ps positive parenting. This was working well until this week I had 2 off my other children to stay at weekend as I do every second weekend and the boys have ganged up on there younger sister only what I could class as bullying. I have removed Internet etc as punishment now both boys are arguing with me and been rude. The one who lives with me is refusing to talk to me and telling me to f off . I can't cope
