I'm posting here for traffic as the parenting board seems more frequented by parents of younger children.
My tall, athletic and very skinny nearly 11 year old is in a very small class with only a small number of girls, a few of whom are both more "grown up" than she is and also (this is relevant) very slightly overweight. Not hugely, by any means - I'm sure they'll all be the same weight by their teens, but for whatever reasons, they go on about it A LOT, especially when changing for PE. "OMG I'm so FAT - LOOK at how fat my tummy is!" and grabbing their tummy fat and making a big deal about it (DD told me this in floods of tears last night).
My DD, conscious of not being very "grown up" or tweeny yet, has started worrying that she is also fat, and maybe she should be worried as well, so now I have a sobbing little girl convinced that the mere presence of organs in her abdomen means she is "squishy" and "fat".
We have had some gentle, rallying talks about this (including some basic biology about what is supposed to be in there!) and she is reassured for now. Intestines are good, after all!
I have tried to strike a line of taking her seriously (I don't want to put her off confiding in me by telling her she is being ridiculous) and explaining the obvious facts, while being super careful not to be critical of the girls who have started all this going around in her head, because they have their own complex reasons for going on about it, and everyone's body is different. Puberty is kicking off with them all, and they're all developing at their own normal, healthy speeds, so it's natural that they are all suddenly more aware of their bodies and talking about it.
Anyway. I'm worried, and want to head this off effectively. Are there any magic phrases, resources, books, something I can read that will give me a better stock of answers to her questions and reassurances?
She is being quite hard on herself generally right now and we're being super gentle and encouraging about everything.
