Depends some on ht: Expected weight range varies with the height of a kid as well as age. You can find a chart of expected weight at www.Healthychildren.Org.Put "growth chart" in the search bar and select female .If you put the kids height on the chart at her present age it gives you a position showing how that compares with others.Locate a similar percentage point on the weight chart below to find expected wt range.
