T.P.
My suggestion is don't buy the sweet treats and chips and soda. I grew up a little overweight as a kid, but very active and was horribly teased even though I wasn't "fat". Now that I am a mom of 2, I realize that the main reason I was overweight is that my mom was a thin junk-a-holic, so there was never a limit as to what I could eat. I ate chips, soda, cupcakes, snacks because that is what I wanted and it was available in the house. I would choose it over healthy foods every time. My parents had dieticians to see me, etc., but nobody ever told my parents to stop buying junk food. Let her eat as much healthy food as she wants. If it's not in the house, they won't eat it and you all will be healthier for it. It's a hard thing to do, but pretty much the only thing that will truly work. Good luck!
