My son is so mean. He will hit, scratch, pinch, pull hair. He will even pull his own hair. Idk why he does it or what I can do. Anytime he does it I will seat his hand and tell him no that’s it’s not nice. But he seems to not care and finds it funny
Have you tried ignoring it? I know it sounds strange but sometimes they do it for attention so when they don't get it they'll quit
