I get phone calls from teachers about her behaviour, she gets put in the "Informal exclusion room", she gets detentions constantly. I don't know whether it's just because it's not cool to be good in scholl but it's effecting her grades massively, she's starting GCSE work next year, I'm worried she's never going to take this seriously. I've tried talking to her about it, she only storms off to her room. I've stoped her going out on weekends and after school when she gets put the IER but she just says she doesn't care. At home she's perfectly fine, does her chores, keeps her room today, helps me out without me even asking her to. Yet she seems to be a completely different girl at school. I know I should know how to discipline my own daughter but nothing seems to be having any effect on her. That she wants to admit anyway. I've talked to her and she said school is fine, doesn't love it but doesn't hate it either. She has good friends there and seems to get on with loads of kids in her year. So why can't she stay in any of her lessons for more than 20 minutes?
