Your baby grows more in the first year than any other time. While every baby is different in how much growth occurs, you can help by providing the right support and nutrition.
What is the difference between your baby's physical growth and development?
Your baby's physical growth indicates the increase in his length and weight, while development refers to his ability to engage in more coordinated actions and thought processes. The first year is crucial for cognitive, social, emotional, and language skills, as well as for physical development.
Your baby's physical growth in year 1
Infants range in size and grow at different rates. While there are general guidelines, if your baby is above or below these averages, there's no reason for concern.
- From birth to 6 months, you can expect your infant to grow 1/2 to 1 inch a month and gain 5 to 7 ounces a week.* By 5 to 6 months of age, he might double his original birth weight.
- From 6 to 12 months, your infant might grow 3/8 inch each month and gain 3 to 5 ounces a week.* By 12 months, he might have tripled his original birth weight.
- It is important to note that your baby's specific height and weight are not as important as making sure that there is a steady rate of growth.
