Hi Margaret. You are not alone my daughter is going to be 9 years old and she is taking the same amount of meds as your child. Yes, she has gained weight. If it helps you any my daughter is 55" tall and weighs 80 lbs. Last year she was around 68 lbs. She is not heavy. She eats like a savage. I somewhat try to watch what she eats. She is also developing at a fast pace.
