Please help!
DD is only 13 months. She has biten me on several occasions and has actually left bruises on me. I have told her off and so has DP but she thinks it is hillarious. She has just bitten my stomach when we were putting her to bed and has nearly broken the skin. I am 6months pregnant and she really hurt me. DP really told her off, but she litterally rolled on the floor giggling. She has had me in tears tonight. She has also headbutted me on my check bone twice tonight although I think that is less of an issue as she was just playing and got a bit rough iyswim. But the biting is done purposely and nothing is working to get her to realise it is wrong. She thinks it is funny and tries to do it again. It is hard to tell when she is about to do it though as she just looks like she is going to give a cuddle or whatever until you feel her teeth! She is also teething quite badly (think her back teeth are hurting her) but I don't think it is just because of this.
Getting really desperate now and I am worried she is going to do this to another child and really hurt them. She has attempted to bite a 5 year old before but didn't manage to do it very hard thank goodness.
