I'm sure you have already answered this question a million and a half times, but my 11m old daughter hits me a lot. It often hurts, and it seems that she displays this aggresion just towards myself. This has been going on for about a month now. At first I tried smacking her on the hand fairly hard, and telling her "NO" firmly, but she actually would just laugh at me! I have tried acting sad and telling her it hurts, but that doesn't work either. I am desperate to get this problem under control before it turns into a bigger problem. How exactly do you disipline an 11m old when they don't really have a concept of cause and effect? Thank you for your help!
