I was stick thin. I don't remember my weight but I do remember I was only 99 lbs at 19 so I must have been REALLY skinny at 12.
My dd, nearly 18, is very petite. She started at 12. She eats a lot of dairy and meat (in the US) so I suppose there are lots of hormones in her system.
My little dd, 8, lives in Prague with me. There are less hormones and preservatives in the meat here. We get fresh, local meat and actually know the butcher. She eats dairy, though, however the dairy here tastes vastly different than the dairy I remember eating in the US. I dunno if it's made differently in reference to hormones, etc. She shows no signs of early puberty. She's also quite petite.
sunnysideup, thanks for that link. I need to take the time to read the article!
