Normal Growth

Growth involves length and weight of the body, and includes internal growth and development. A child's brain grows 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, when 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):

AgeHeight

334.5 to 4035.5 to 40.526 to 3826 to 38
437 to 42.537.5 to 4328 to 4430 to 44
642 to 4942 to 4936 to 6036 to 60
847 to 5447 to 5444 to 8046 to 78
1050 to 5950.5 to 5954 to 10654 to 102
1255 to 6454 to 63.568 to 13666 to 130
1459 to 67.559 to 69.584 to 16084 to 160
1660 to 6863 to 7394 to 172104 to 186
1860 to 68.565 to 74100 to 178116 to 202

Although a child may be growing, their 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, consult your child's doctor.
