Newborn (0-3 months)

Immediately after birth, a newborn loses about 5-10% of his or her birth weight. However, by about 2 weeks, babies should start to gain weight and grow quickly.

During normal baby growth, your newborn grows faster in the first few months than at any other time in life. If your baby is breastfeeding, it's important that she be fed every 2-3 hours (8-12 times per day). If she's bottle feeding then she will normally eat every 3-4 hours in the first few weeks.

Every month after the first, he or she should gain about 1.5-2 pounds and grow 1-1.5 inches. And, a good thing for moms and dads, a newborn may sleep 16-17 hours a day the first month of life.

Did you know Enfamil® created the first formula tailored for newborns through 3 months? Enfamil PREMIUM® Newborn provides the nutrients needed to promote healthy baby growth.

Infant (4-8 months)

During the second half of the first year of life, infant growth is not as rapid. However, an infant needs more calories in relation to size than a preschooler or school-age child.

Every month, your baby should gain about 1.5-2 pounds and grow 2-3 inches. An infant's weight by 4-6 months should be double her birth weight.

Enfamil NeuroPro™ Infant provides tailored nutrition needed to promote healthy infant growth for babies 0-12 months.

Toddler (9 months and up)

By 8 months, the average boy will weigh between 14.5-17.5 pounds, while girls will weigh about a half-pound less.

At 1 year of age, the typical child weighs about 3 times her birth weight. However, between ages 1-2 a toddler will gain only about 5 pounds.
