She's been buying more sweets than I would have liked since she started secondary school. I've been trying to just nicely explain nag that it really isn't good to eat that much sugar, but I'm starting to worry it's getting a bit compulsive.
She is very secretive about what she eats. She hides wrappers in her room. She can't explain where the money comes from.
Today I found a carrier bag in her school bag containing an empty coke bottle and wrappers from a skips packet, large bag of haribo, sherbert thing and fruit pastilles. I know none of it was in her bag yesterday. I also made a point of only giving her £1.75 this morning, as that's what she needs to cover her lunch. Even if she didn't buy any lunch there's no way she could have bought all that.
She's not overweight but isn't as slim as she used to be. She has access to plenty of snacks at home, including things like bagels, mini pancakes etc and she eats healthy meals (although won't eat much breakfast).
She has relatives with diabetes on both sides of the family, and she was aware last year that my brother aged 36 was in hospital and nearly had to have his foot amputated. It scares the hell out of me that he behaved exactly like this as a teen.
I don't know if I should come down hard, such as by checking her bag or refusing to give her any dinner money, just a packed lunch, or just back right off because the more cross I get the more it's like forbidden fruit.
