Your daughter is well beyond the upper limits of the spectrum for girls her age. To give you some idea, the 95% for height for a five and one-half y. o. girl is 47 inches; the 95% for weight is approx. 52 lbs. So, she is quite big for her age.
I'm FIVE foot 2 and that weight, and I'm proportionate. I would say your child is more likely overweight, but I'm not a doctor.
