DD has just started secondary and I give a couple of quid a day for school lunch, she is not big on sandwiches and had hot meals at primary. I know she buys sweets and goes in the sweetshop before and after school daily as do her friends as she has admitted it a few times. A couple of times I drove past her on the way back from school (I pick my other DC up from another school and sometimes pass her on way back, she walks with friends) and she will hide stuff behind her back (ie junk food) while waving, I offered her a lift once and she dropped half eaten sweet wrappers on the floor right in front of me and denied they were hers. I don't expect her never to buy sweets/junk but am worried about weight gain etc (she is putting on weight although not fat) and the money is for lunch not crap, I haven't got money to throw away either. She does get pocket money which she also spends on junk sometimes. Is it control freakish to expect to have any say what she buys at this age? Should i just let her buy it? Put her on butties? Give her less money? I have tried to encourage healthy eating and said sweets in moderation are OK but it is falling on deaf ears it seems. Any advice?
