Growth charts are equipment your pediatrician can use to keep track of your child”s physical growth. During each checkup, the doctor will measure your babys length, weight, and head circumference. The doctor can then compare the measurements for your baby to a chart of national averages for infants of the same age and sex. The result is that the doctor should be able to tell you what percentile your baby is in when compared to averages for babies around the nation. For instance , if your doctor tells you your 4-month-old is in the 86th percentile for weight, that means 86 percent of the two-month-olds in your world weigh less, and that 14 percent weigh more. A baby that is at the 50th percentile in either height or weight is right at the national popular.
