She’s 13. We can’t prove it but it’s only DH and I and he put £50 in a drawer last night and £20 is gone today. Nobody else has been in the house and our other DC are too small. She’s been sneakily taking things (e.g my makeup or jewellery, chocolate/crisps/fizzy drink) and then refusing point blank to admit it even when caught red handed. She lies about little things like brushing her teeth and has several times been caught with social media accounts she’s not allowed to have. She comes home from school with sweets and energy drinks that ‘her friends gave her’.
We are at our wits end here. She can be so loving and lovely. We have a good relationship and really most of the time she would get get the things she wants if she would just ask (but she NEVER does). Things are good with her mum and that side of the family too. She has a nice life there and a nice life with us (although I do appreciate that having 2 separate lives must be incredibly difficult for a child even if that’s all she has ever known).
Any advice would be so so appreciated. We just want to get to the bottom of this behaviour and help her.
