Understanding Child Growth and Development
Learn about growth percentiles, WHO/CDC standards, and healthy development patterns
Growth Percentiles Explained
Growth percentiles show how your child's measurements compare to other children of the same age and sex.
Understanding Percentiles:
WHO vs CDC Standards
WHO Charts (0-2 years)
Based on breastfed children from 6 countries, representing optimal growth
CDC Charts (2+ years)
Based on US population data, reflecting typical growth patterns
Best Practice
Use both for comprehensive assessment and comparison
