Please advise. My 12 DD is behaving so badly. We've caught her vaping, stealing money, stealing sweets and biscuits she finds in the house. Horribly cheeky and nasty attitude. I'm at end of my tether. I don't want to take her phone away completely as I want to stay in touch with her for safety reasons. I have also just found pics of her friend online that are quite provocative, (school uniform but hiked up skirt, sticking out chest, singing dirty songs it's so worrying) and DD has a (locked) account as well which she was forbidden to have. The friend I think is problematic and is allowed to stay out late, go into the city nearby etc which I would never allow my DD to do. She has been in trouble with behaviour in school as well. I think she must be so unhappy. She is copying this girl and I'm worried sick. I'm going into school on Thursday to speak to them. I'd move her to a new school but we don't have much choice in the area or much money to move her further away. Any advice or help would be welcome I'm just so sad. We've had numerous talks about it all. Some end up in shouting, screaming even, most just in tears. We've tried trusting her, she took us for idiots, as well as talking it through. I'm worried she is unhappy and may sink lower. She is basically a good kid and we are stricter than most of her friends parents. Please help if you can relate or think of anything more I can do.
