my moms friends daughter is 78 pounds she is very active and she runs about every day is that normal?

yeah, it depends on how big the girl is. like how tall. does she eat like normal?

It depends on how tall she is, but she sounds healthy so far. I have a sister-in-law that is 17 5ft 2 inches and she was weighing 80 pounds. She had a problem with her period coming every couple of months. She was put on some kind of shakes to help her gain weight and that has helped her. But mind you that she always ate very well.

NO! when you're 12 or 13 the normal weight is 95-115.

She is way too small and make sure she isn't anorexic. It might just be pressure at school.

Both of my daughters around that age are thin because we eat a healthy diet and they are very active (no video games). I think because the obesity rate in children is on the rise, our minds are changing what should be normal.

As long as she is healthy then it is fine. Some girls still have not started to mature at that age and they are smaller. My daughter is almost 4'9 she is 10 and weighs 58 pounds but she is active and healthy.

My 11 year old is 5'6" and weighs 97 pounds she takes Kung Fu and dance classes five days a week is that normal? There is NO normal for kids. ALL kids grow and develop at their own pace.

It all depends on height.

It depends on her height.

she's like me but a bit bigger

Well, she's trying to be healthy...
