What can an 11-year-old girl do if her weight varies from 80-93 pounds but her stomach is pudgy?

I am a Registered Nurse on a pediatric floor and I also have a 12 year old daughter. 80-93 pounds is a good weight for an 11 year old girl unless the girl is really tall for her age then she would need to weigh more. "Pudgy stomachs" will go away as the girl gets taller and also after the girl begins to menstrate. With a weight of 80-93 pounds the girl should not be dieting. She could get plenty of exercise and eat good foods like fruit for snacks and also stay away from sugared sodas and chips and snack cakes. Anyone wanting to be healthy should do those things. My daughter is 12 and she weighs 115 and wears a size 3 or 5 in juniors. She looks perfect to me!!
