Should a 10-year-old weigh 115 pounds?

IT ALL DEPENDS ON HER HEIGHT. A BODY MASS INDEX (BMI) CHART WOULD TELL YOU WHAT A DOCTOR IS GOING TO SAY BUT IT REALLY COMES DOWN TO THE BODY TYPE. MY GIRLFRIEND IS 18 AND WEIGHS 100 POUNDS BUT SINCE SHES 4 FT 9 IN SHES NOT REALLY UNDER WEIGHT. google BMI CHART AND GO FROM THERE
