Dd is 9.5. She was always quite skinny as a toddler but over the next few years started to fill out a bit.
About a year ago I realised she might be overweight 
Anyway she is now about 4'8" tall and 6 st 5lbs. This varies depending on which website I look at from the top end of 'normal' weight to a bit overweight.
I'm a bit worried. But you have to be so careful about body image, there's no way I want to convey to dd I am worried about her weight. She does have a big appetite though and I'm sure it's to do with portion size rather than what she eats.
