đThe first year of life is a time of amazing change during which babies, on average, grow 10 inches (25 centimeters) in length and triple their birth weights.
After age 1, a babyâs growth in length slows quite a bit. Between ages 1 and 2, a toddler will gain only about 5 pounds versus the tripling of birthweight that they experienced during their first year of life.
