Normal Growth

Growth involves not only length and weight of a body, but also internal growth and development. A child's brain will grow the most during the first five years of life, reaching 90 percent of its final size. Growth also affects different parts of the body at different rates; the head almost reaches its entire size by age 1. Throughout childhood, a child's body becomes more proportional. Growth is complete between the ages of 16 and 18, at which time the growing ends of bones fuse.

Pediatricians use a range to describe normal growth for a child. The following are some average ranges of weight and height, based on growth charts developed by the Centers for Disease Control and Prevention (CDC):

127 to 31 inches28 to 32 inches15 to 20 pounds17 to 21 pounds

Although a child may be growing, his/her growth pattern may deviate from the normal. Ultimately, the child should grow to normal height by adulthood. If you suspect your child is not growing properly, always consult your child's physician.
