My little girl has stated to hit scratch and pull my hair, she isn't doing it in an angry way either she laughs when she does it , she really hurts and it doesn't seem to matter what i say or do it doesn't seem to work. Ive tried telling her NO that hurts mummy its not nice and walking away from her ,ive tried shouting, ive even smacked her leg only lightly which she just laughed at and lunged for me again, and it made me feel horrible. I dont know why she has become spiteful because we never show her any violence and she doesn't see it at all, we never smack her, except that one time and it was more of a tap really. Has anyone else experienced this and have any ideas why she might be doing it. It seems aimed mostly at me and her daddy and mostly of an evening when maybe she gets a bit excited playing and tired.
