When it comes to monitoring your baby's growth and development, healthcare professionals in the U.S. often refer to two tools: the CDC (Centers for Disease Control and Prevention) and WHO (World Health Organization) growth charts. These charts both assess weight, height, and head circumference. Let's break down the difference between the two:
WHO
WHO charts show children's growth in six countries (including the United States) based on environments believed to support optimal growth. The WHO growth charts use the growth of breastfed infants as the norm for growth.
Pediatricians will typically use the WHO charts with all babies regardless of feeding from birth through 2 years old.
CDC
These growth charts represent how U.S. children and teens grew primarily during the 1970s,1980s, and 1990s. The CDC actually recommends using these charts after the age of two.
CDC and WHO growth charts are essential tools for tracking growth and development over time. They can help identify potential issues, such as slow growth or rapid weight gain, which may require further evaluation or intervention. It's important to note that while growth charts provide valuable information, they are just one part of the comprehensive assessment of your baby's health.
