The Center for Disease Control and Prevention has separate charts for infants from birth to 36 months, children and adolescents aged 2 to 20 years, and preschoolers aged 2 to 5 years. Length for age and weight for age are on the chart for infants, as are head circumference for age and weight for length. If children are able to stand at the age of 2, the chart for older children is to be used. If a child is unable to stand, length can be assessed on the birth to 36 months chart until the child reaches the age of 36 months. On the children and adolescents charts, there is information for stature for age and weight for age, as well as body mass index for age. The preschooler's chart shows weight for stature.
Charts are separated by sex to indicate differences that exist in average growth of boys versus girls.Learn more about Parenting
