What is the average weight for a 2-year-old?

The average weight of a 2-year-old boy is between 24.8 to 28.9 pounds, and the average weight of a 2-year-old girl is between 23.3 to 27.5 pounds. At this age, parents should see their babies slowly put on weight day by day although the rate will vary. Some fluctuations are to be expected.

Monitoring the baby's weight at this time is crucial to determine whether there are any developmental problems present. A failure to gain weight can be an indication of a serious underlying health problem. Most physicians will deem failure to gain weight if the baby:

• weighs 20 percent less than his or her ideal weight
• exhibits a decrease of two or more major percentile lines on the growth chart from previous checkups
• fall below the third percentile for weight on the growth chart
