depending on her height, i'd say probably not. I've been around 5'0 for a good while, and 115 is a healthy weight for me, so unless she's pretty short, no.
No, everyone has their own healthy weight. You are only overweight if YOU think you are.
how tall are they
Absolutely not!
no
Yes.
depends on your size
No, 115 pounds is a healthy weight for somebody that height and age.
Yes. Because a healthy 9 year old weighs that much.
According to BMI standards, it is within the normal weight range. So, it's technically not overweight.
She's 5'1... IF she has a small frame then...106-118lbs IF she has a medium frame then...115-129lbs IF she has a large frame then...125-140lbs
Unless there is a medical reason yes she is
Unless she's really tall that would be overweight.
