So today my daughter when my dd was putting on her swimming cossie she said,'look at my fat legs.' 
she's referred to herself having a 'fat tummy' recently.
When i was growing up My mum had an eating disorder. I did too in my teens, i had councelling, recoved and I am sensitive to how awful and corrosive a negative self image is, so I've always been really careful never to critic my own body or those of others in front of my children. My own body image is healthy.
My dd does non girly sports like a martial art, football and because I grew up with such a screwed up attitude to food I have consciously tried to make cooking and eating a shared and enjoyable thing.
I told my daughter that she has a beautiful, strong body and asked why she called her legs fat. She wouldn't answer and just said that they were.
I'm scared and would appreciate any advice here.
Thanks.
