Lisa,

Just to back up what Julia-Ct said!!! 90 pounds is NOT fat!! Also sounds to me you are doing all the proper things for a healthy diet.

I have a 8 year old (non cah) daughter who is 93 pounds!! We have struggled with weight her whole entire life. Yes, she does get a little junk food...BUT as a whole, we eat healthy. She struggles with ADHD and also genetics as far as weight. I have to watch my weight. Both sides of her family tend to be heavy. I have a 13 year old(non-cah)  daughter who is "thin and getting curvy"............BUT didnt get that way until all the hormones kicked in.

Be supportive and you are your daughters best advocate!!!

Take care-

Lesly
