Hi Im having major problems with my DD who will be 11 in November. Shes always been assertive and able to stick up for herself but it now seems like its gone into overdrive and Im wondering whether its hormonal. Shes constantly arguing, shouting and at times screaming at me and her 2 sisters, the middle one shes particularly awful to (8 yr old) -I have to physically separate them at times, slamming doors and general arsey behaviour. Im on my own with them all as I left my husband 2 years ago and our divorce is coming through in a few weeks. I left before the atmosphere was bad enough for my girls to see and feel we've all coped remarkably well with everything. However my DDs behaviour is really upsetting me as its happening at school. Ive been called in several times by the head about various spats with a couple of girls and the latest one this morning shed been overheard swearing at one of the girls which is hideous as she knows we abhore that sort of behaviour. Ive tried most things like banning Guides which she loves - I wont let her have a mobile yet as I feel shes too young but had said to her i may let her have one in yr 6. Shes due to sit the 11+ in Sept and has been doing extra work but doesnt seem that stressed about it and academically is doing really well at school but I feel she may need some time on her own with me. Just dont know what to do with her!! Please help!!
