It very much depends on how tall the girl is to determine how much she should weigh. Other factors should be taken into consideration such as overall health, diet and lifestyle. If you are concerned about your weight or your child’s weight you should consult your doctor, as there are various programmes and support in place to help with weight concerns for children and adults alike.
On average though, using a healthy weight chart found on the Weight Loss Resources website (www.weightlossresources.co.uk/body_weight/healthy_weight/cha) you can find out how much you should weigh by looking at your height and following the chart to reach the healthy weight range. It is important to stress though, that this chart and website are aimed at adults and not children; as children’s bodies are still growing right up until they go through puberty, any excessive weight found on a nine year-old is most probably what we call ‘puppy fat’and will disappear as she grows older. Another useful source to perhaps more accurately determine the ideal weight of a nine-year-old girl is by visiting the About.com Pediatrics site and using this calculator: pediatrics.about.com/cs/growthcharts2/l/bl_ibw_calc.htm It allows you to input the girl’s current statistics, i.e. Height, current weight, age, etc. To give a detailed result at the end with further links to other useful resources. It uses pounds to measure the weight though, so it is worth finding a weight converter online if you do not know the weight in pounds. The website also has a Body Mass Index growth chart for girls aged 2-20 which can also be of use: pediatrics.about.com/library/growth_charts/ngirlsbmi.htm
