Quoting JessieLeeAnne:" I wouldnt have said anything and tried holding back any "ows!" The reaction is probably what is getting him to continue. I would probably pinch him back at this point... "
I usually warn him to stop and then if he doesn't, I ignore and he goes on screaming and pinching until he realises I'm not paying attention. I just got a double handed attack from him for closing a door to a room he isn't allowed into and flat out ignored the situation and he screamed for a minute and now he's watching Play School so that seemed to work.... Maybe I'll just keep doing that
But my poor leg! At least I've shaved them. When he does the arms, he rips the hairs out too
