Let me rephrase...what is the average height and weight of a 5 year old girl?

I am concerned that my daughter might be slightly overweight so I want to know what other people think. She is 47 pounds and about 43 inches in height (just over three and a half feet). I don't have anyone to compare with so aside from asking the doctor, I thought I'd ask Yahoo Answers. Your info. would be helpful. Thanks.
