I am running out of ideas.
Usually we take a toy but DS had so many it doesn't seem to have an effect anymore as he just plays with something else and doens't miss what we have taken.
Sometimes I send him to his room, a time out for him and me. He usually is up there for a little while, then wants to rejoin the family and apologises. It doesn't stop the actual behaviour though (appalling attitude at the moment, he is 5).
We will ban the tv but this also affects DD then which isn't really fair. He doesn't seem that bothered though as he just goes and does something else.
I really am running out of ideas completely. We stop treats, I'm not sure he is that bothered either. Arrgggghhhhhhhh.
