What Is A Percentile?
A percentile tells you how your baby compares to other babies of the same age and gender for a specific measurement—like weight, height, or head size.
Example:
-
If your baby is in the 60th percentile for weight, that means they weigh more than 60% of babies their age and less than 40%.
-
If they’re in the 10th percentile, they weigh more than 10% and less than 90% of babies their age.
What’s “Normal”?
-
Anywhere between the 3rd and 97th percentile is generally considered normal and healthy.
-
What matters most is your baby’s growth over time, not a single number.
Track the Pattern
-
Consistent growth on their own curve is a good sign—even if they’re in the 15th or 85th percentile.
-
Sudden drops or jumps in percentile might warrant a check-in with your pediatrician.
