I can't cope with my 8 year old daughter any more. She lies, hits her older brother (10 & 3), and purposely antagonises them. 2 days ago she burnt a hole in the carpet with the hairdryer, which was an accident, but she didn't tell us, and when we found the burnt hole she denied it and denied it until eventually admitting it when it was so obviously her. I told her I was annoyed that it had happened but accidents do happen and I was much more cross that she didn't come and tell me (could have set the house on fire) and that she lied about it. Tonight when I collected her and her older brother from school, when we were walking to the car she keeps barging into him so I told them to walk separate sides of me. She won't eat her tea and tells me she has tummy ache. Fine. Then it's time to get ready for swimming for the older 2, so they go and get their clothes and she blocks her brothers way walking slowly all the way up the stairs. Then I hear a scream and cry so rush upstairs and she's hit her brother. Again. At the weekend I had a talk with her after she hit her brother and said she really needed to think about her actions and other peoples feelings and that hitting anyone was totally unacceptable behaviour. And here we are again. I don't know what to do! She's now not going swimming or to brownies (which she really enjoys) but I just get the feeling she's not really that bothered. No matter what I do she just doesn't seem to care. She'll cry a bit at the time but it doesn't affect her bad behaviour. When I ask her why she does it all she can say is she doesn't know. At other times she can be the sweetest child and often makes cards/pictures for me, or helps play with her younger brother for a few minutes, and is very loving. What do I do???
