In some children, gains in height occur so much more quickly than gains in weight and muscle that they may begin to look quite skinny and fragile. But this doesn’t mean they are unhealthy or that anything is wrong; such children fill out gradually as their muscles develop.
In general, a preschooler’s growth gradually will begin to slow this year and in the subsequent ones—from about a 5-pound (2.3-kg) gain and about a 3 1⁄2 inch (8.9 cm) increase in height during the third year, and then decreasing to about 4 1⁄2 pounds or 2 kg, and 2 1⁄2 inches or 6.4 cm during the fifth.
However, after age two, children of the same age can vary noticeably in size and weight, so try not to spend too much time comparing your child’s measurements with those of her playmates. As long as she’s maintaining her own individual rate of growth, there’s no reason to worry.
Measure your child twice a year and record her measurements on her growth chart. If her weight seems to be rising faster than her height, she may become overweight, or if her height does not increase at all in six months, she may have a growth problem. In either case, discuss this with your pediatrician.
