Really appreciate some advice on my 6 year old dd. She is well behaved at school and at home. However - on play dates, visiting relatives, when going on holiday we see extreme behaviour. We went away this weekend and she was incredibly rude, flew into a rage when we tried to - calmly - discipline her. She was hitting me, scratching me, kicking me very hard and was trying to bite me. We have a play date tomorrow and I think she will repeat this behaviour. Do you think I should warn the mum, and then just take my daughter home as soon as the behaviour starts?
