When my daughter makes comments about other children's weight, and it's never done maliciously, it's just a real observation. "Oh this girl is so pretty but she's gained weight." Or her own dad, she'll say, "Daddy's a little bit fat." She's very diplomatic. I try and talk to her about not judging and it's okay to be whatever body type, so long as you are healthy and as long as you are a happy and healthy individual; that's what it's all about.
