Your Infant’s Size and Growth Timeline
September 5, 2018
All babies are unique and grow at their own pace. However, it’s always a good idea to be aware of a few baselines and benchmarks for size and growth. At each well-child check, your pediatrician should be providing you with growth charts for your child for weight, height and head circumference (you can find these charts here), but sometimes said charts can be confusing. To simplify the process, we’re going to break down the averages (50th percentile for each category) below. These averages are all based off of the World Health Organization’s standards, and as such, are divided by gender.
Baby Girl Growth Chart
|1 month||21.1 inches||9.4 pounds||14.4 inches|
|2 months||22.4 inches||11.3 pounds||15 inches|
|4 months||24.4 inches||14 pounds||15.9 inches|
|6 months||25.8 inches||16.1 pounds||16.5 inches|
|9 months||27.6 inches||18.1 pounds||17.3 inches|
|12 months||29.1 inches||19.8 pounds||17.7 inches|
Baby Boy Growth Chart
|1 month||21.5 inches||9.9 pounds||14.6 inches|
|2 months||22.9 inches||12.3 pounds||15.4 inches|
|4 months||25.2 inches||15.4 pounds||16.3 inches|
|6 months||26.6 inches||17.6 pounds||17 inches|
|9 months||28.3 inches||19.8 pounds||17.7 inches|
|12 months||29.8 inches||21.2 pounds||18.1 inches|
Remember that these numbers are just averages; the most important thing is that your baby is growing at a steady pace. And never be afraid to consult your pediatrician if you have any questions or concerns about your baby. Your pediatrician should always be your number one resource.
