please help my 8m.o. dd is pinching, pulling hair, scratching and biting so much. i'm not really sure how to react, i dont want to be angry. we've been firm saying "no!" but she thinks it's a game and laughs. she sometimes looks so vindictive when she does these things! we are a very peaceful family so i dont know why she should be, if she is angry. is this a phase she's going through? it really hurts somtimes, especially when breastfeeding. any suggestions??
