What is Adjusted Age?
Adjusted age (also called corrected age) is the age a premature baby would be if born at full term (40 weeks). It accounts for the time missed in the womb and provides a more accurate measure for assessing growth and developmental milestones.
Why It Matters
Preemies need extra time to reach milestones. Using adjusted age prevents unfair comparisons with full-term babies.
How Long to Use
Most doctors recommend using adjusted age until 2-3 years, when most preemies have caught up developmentally.
When to Apply
Use adjusted age for developmental milestones, growth charts, and feeding expectations.
