With Kat, when she hits me, I start the big fake tears and wailing (like she would if I were to hit her) and tell her she hurt me (yes I am an actress and can put on the tears) and she usually comes over and says sorry and kisses and hugs me better. She does the same thing when she hurts jess. The key was, we make a BIGG deal out of how much it hurt the other person and take her hand (we are down at her level at this point) and tell her it was wrong to do it and she has to give cuddles and kisses better. If she refuses, we say it again and she eventually gets the point and gives kisses better. Now I only have to say OUCH! (in a loud voice) and cover my face and she comes straight over to me. Kids this age have no other way to express their anger than to act it out and so hitting and biting is common (biting we stopped by giving her a tap on the bum and telling her NO in a firm voice at her level). Having said that she kicks me when I change her and still does most things she knows she shouldn't. But a STRONG LOUD no from me or her dad is enough to stop her and have her covering her mouth *L*
