If your child or teen starts gaining weight, do you mention it?

So I saw a question on here about someones ELEVEN year old daughter gaining about 30 pounds and her grandmother offered her 3.00 a POUND that she loses. Thats BULLCRAP. Do you have any idea what that does to your kid, when her own FAMILY is telling her shes getting fat? My mom used to tell me I was "gainging weight" when I was in around 6th grade and do you know how it affected me? I STOPPED eating and started making myself throw up and exercise constantly. You think its just an innocent way of helping her, but really you're demolishing her self esteem and making her think theres something wrong with her. If you want her to be healthier, get her involved in a health club and take away all the junk shes been eating. Do it as a family! Dont just single her out as the broken one. Anyways.. now that my little rant is over, what are your opinions?
