Hello, I'm Doctor Gerald Bernstein, director of the Diabetes Management Program of the Friedman Diabetes Institute at Beth Israel Medical Center in New York, and today for About.com, we're going to talk about your child's normal growth.How do we know how the child is growing? The Centers for Disease Control, the World Health Organization, they have all put together growth charts that represent the growth patterns of 95% of the population.Growth and development is the big thing. My kid is the shortest kid in the class and, you know, he's really unhappy because the other kids make fun of him. My kid is the fattest kid in the class. My kid is so tall that he really can't play with the other kids in the class. There are social issues.When you see the pediatrician, he will have placed the child's height, year by year, on a chart. Very often, growth lags in a number of children. The best way to determine where they are on the growth curve, other than looking at the numbers, is to do an X-ray of the wrist.And the maturity of the wrist bones is very much tuned into the bone age of the patient. So you may have a child who is short but the bones are developing and you will recognize that they may not attain great height. On the other hand, you may have a child exactly the same height and you look at the bones and the bones are still immature and you know that there is plenty of growth that will be achieved.Thank you for watching and for more information, please go to About.com.
