dd is 13 and i think she eats too much choc etc. she has choc/sweets every day, after school and,if she can find it, at home, and when she's out with her friends. They all seem to do it. I've stopped keeping choc at home (which is a bit rough on those of us who relish a pre-menstrual Mars Bar!) but she just gets it elsewhere. I've tried not to nag about it, cos I thought that might have the opposite effect. She has no weight issues but I know it's not doing her any good, or her teeth. What really annoys me is when she goes out with her friends and buys crap muffins or whatever, then doesnt want her tea when she gets in. Then she's hungry later and has, yes, more crap - usually cereal.
I dont want to go all OTT and ban all treat foods (and that would mean for all of us), but she doesn't seem to able to control herself!!
