About CDC Growth Charts
The CDC provides growth charts based on data from healthy babies born at a normal weight. These charts help track:
- Height-for-age
- Weight-for-age
- Head circumference-for-age

Growth charts are updated periodically as new data becomes available. The most recent charts are based on data from 2000-2002 and 2011-2014.
When to See a Doctor
Consult your pediatrician if your baby's growth falls consistently below the 3rd percentile or above the 97th percentile for three consecutive months.
