If your baby was born early, your baby has two ages: chronological age and corrected age.
- This is the age of your baby from the day of their birth. For example, if your baby was born on June 1 and today is December 1, then your baby’s chronological age is 6 months.
- This is the age of your baby based on their due date. For example, your baby was due on July 1 but was born 2 months early on May 1. If today is November 1, then your baby’s corrected age is 4 months. Your family doctor or paediatrician will often use your baby’s corrected age to decide if they are growing and developing well.
