â ïļ Please check your inputs
ð Your Results
ð How It Works
What Is Corrected Age?
Corrected (adjusted) age subtracts the weeks your baby was born early from their chronological age.
Weeks Early
Weeks early is the gap between the actual birth date and the due date.
Worked Example
A baby born 8 weeks early at a chronological age of 4 months has a corrected age of about 2 months.
Until Age Two
Pediatricians and the AAP recommend using corrected age for milestones, growth, and early vaccines until about 24 months.
ðĄ Why It Matters
ðķ Standard Practice
Corrected age is the AAP-recommended method for evaluating a premature baby's development.
ðŊ Less Worry
Comparing a preemie with full-term peers causes needless anxiety â corrected age gives a fair baseline.
ðĐš Better Tracking
Growth charts and milestone checklists line up far better when you use the corrected age.
