How much should a 7 year old female weigh that is 51 inches tall?

I would say around 50 to 60 pounds should be average - all the websites I checked out said random things like "your child should be 123 pounds" which is completely off, my daughter who is eleven isn't even 123 pounds, and on one of the websites which said your daughter should be 63 pounds (4 stone and 3/4), well my eleven year old is 5 stone, although she is a little underweight , still. Hope I helped!
