Detailed explanation-1: -In general, length in normal-term infants increases about 30% by age 5 months and more than 50% by age 12 months. Infants typically grow about 10 inches (25 centimeters) during the first year, and height at 5 years is about double the birth length. In boys, half the adult height is attained by about age 2.

Detailed explanation-2: -Healthy infants come in a range of sizes. But looking at the average growth, most babies have tripled their birth weights by the first birthday. Their heads have grown by about 4 to 5 inches (about 10 to 13 centimeters). And most babies grow about 9.5 inches (24 centimeters) longer in the first year.

Detailed explanation-3: -During this second year of life, growth slows down. Your toddler may gain about 5 pounds (2.27 kg) and grow about 4 or 5 inches (10 to 12 cm). By 2 years, children have reached about half of their adult height and 90% of adult head size.

Detailed explanation-4: -As you’ll see, there’s now a much broader range of what’s “normal” than there was at earlier ages. At fifteen months, the average girl weighs about 23 pounds (10.5 kg) and is almost 30.5 inches (77 cm) tall; the average boy weighs about 24.5 pounds (11 kg) and is 31 inches (78 cm) tall.

Detailed explanation-5: -Physical growth is especially rapid during the first 2 years. An infant’s birthweight generally doubles by 6 months and triples by the infant’s first birthday. Similarly, a baby grows between 10 and 12 inches in length (or height), and the baby’s proportions change during the first 2 years.
