Infant growth: What''s normal?

Infant growth rates depend on various factors. Consider what''s typical during baby''s first year.

QHow much should I expect my baby to grow in the first year?

AAnswer Section

Healthy infants come in a range of sizes. Still, infant growth tends to follow a fairly predictable path. Consider these general guidelines for infant growth in the first year:

  • From birth to age 6 months, a baby may grow 1/2 to 1 inch (about 1.5 to 2.5 centimeters) a month and gain 5 to 7 ounces (about 140 to 200 grams) a week. Expect your baby to double his or her birth weight by about age 5 months.
  • From ages 6 to 12 months, a baby may grow 3/8 inch (about 1 centimeter) a month and gain 3 to 5 ounces (about 85 to 140 grams) a week. Expect your baby to triple his or her birth weight by about age 1 year.

Your baby''s doctor will track your baby''s growth at routine well-baby exams, likely marking your baby''s growth on a standard growth chart.

Keep in mind that many healthy babies go through brief periods when they stop gaining weight or even lose a little weight. A doctor is likely to be concerned only if a baby doesn''t gain weight from one well-baby exam to the next. Your baby''s position on the curve in a growth chart isn''t as important as the trend of the curve overall.
