Very true - and now that I'm starting to watch what I eat, I'm hoping it rubs off on them and they start losing too. It's the catch 22 - they get aggrivated when I say something isn't really good for you to eat - and want to eat it, but I have finally noticed my 15yo checking portion size and calories, so hopefully something is soaking in!!
I am luckier than some, even though I am gone to work already - the girls can call my mom who lives close by to pick them up and take them to school if it is too awful bad outside. They know it's a worst case senario call - can't do it every day, but at least grandma is there.
