My 3 year old daughter has been hitting friends recently. I always deal with it by telling her off and taking her away until she says sorry. Today was the worst - first of all, I caught her on her friend's back when she was on the floor, walloping her head and trying to bite her back. We then found them in the ball pool with my daughter shoving her friend hard under the balls. Her mum had to dig around for her daughter, who was terrified. How the hell do I deal with this? I don't want to talk to her, let alone play with her. Even worse was when I told my husband, he said oh, it was only plastic balls!
