The average newborn is 19.5 inches tall and weighs 7.25 pounds. According to the National Center for Health Statistics, boys have a head circumference of about 13.5 inches and girls measure in at 13.3 inches.

5 Days to 3 Months

Babies gain about one ounce per day, on average during the first three months. This equates to roughly half a pound per week but they should be back to their birthweight by their second-week visit. Parents should expect a growth surge around 3-weeks and then another one at 6-weeks.

3 Months to 6 Months

A baby should gain about half a pound every two weeks. By 6 months, your loved one should have doubled his or her birth weight. During this stage, it’s imperative to show affection to your baby. Hug, kiss, and play with your child; physical contact builds a connection with your baby and stimulates them to move their whole body.

7 Months to 12 Months

Your child is still gaining about a pound a month. If you’re nursing, your baby may not gain quite this much, or they may dip slightly from one percentile to another. “At this point, babies may also burn more calories because they’re starting to crawl. Even so, by the time your toddler reaches their birthday, expect him or her to have grown 10 inches in length and tripled their birth weight. Their head should grow by approximately another 4 inches too!

Growth for Toddlers, Preschoolers, and Big Kids

Age 1

Toddlers will grow at a slower pace this year but will gain about a half a pound per month and will grow a total of about 4 or 5 inches in height. This is the perfect time to boost your baby’s motor skills as they’ve already started walking.

Age 2

Your child will sprout about 3 more inches by the end of their second year of life and will have quadrupled their birth weight by gaining about 4 more pounds. By now, your pediatrician will be able to make a fairly accurate prediction about her adult height.

Ages 3 and 4

A preschooler will grow about 3 inches and gain 4 pounds each year. You may also find that your child starts to shed the baby fat from his face and look lankier; kid’s limbs grow more by the time they are preschoolers.

Ages 5+

Kids will grow about 2 inches and gain 4 pounds each year until puberty (usually between 8 and 13 for girls and 10 and 14 for boys). Girls often reach their full height about two years after their first period. Boys usually hit their adult height around age 17.

How Tall Will Your Baby Be?

Most pediatricians do a rough estimate based on the following formulas:

For Boys, Add 5 inches to Mom’s height and average that number with Dad’s height.

For Girls Subtract 5 inches from Dad’s height, and average that number with Mom’s height.
