A lot of time she is a sweetie and at school there doesn't appear to be issues, at least that's what her teacher says and it's all I have to go on! However, when at home with her younger brother and sometimes with friends she can be really mean and nasty. I'm aware that it's probably worse when I am there, not sure if it still is when I'm not. She will not share something, or let other children borrow something like a cup to have a drink. She will deliberately do things to upset her brother and occasionally her friends. We were talking about ds's party and said we were picking up one of his friends, to which she said 'I hate him' - she doesn't even know him! She will sometimes find that something she does in fun, such as tickling, upsets a friend and instead of stopping she will carry on and laugh :( I really hate this nasty side of her and really don't like her when she shows it, which is a lot of time after school, especially with her brother. What do I do about it? I find I react to everything, which I know I shouldn't but it makes me so cross. I also don't feel as though I can let her get away with it as it's such horrible behaviour. I know this is all a bit rambling but everything feels like a battle at the moment and it's sad not liking my dd a lot of the time. Any advice would be gratefully appreciated.
