44. Will my children’s development be based on an adjusted or corrected age that factors in the number of weeks the babies are born premature? If so, for how long?

A baby’s actual age is how old they are from the time of their birth. An adjusted age or corrected, used for infants born prematurely, is calculated from an expected due date. As an example, quadruplets born 3 months ago at 32 weeks gestation have an actual age of 12 weeks (or 3 months), but an adjusted age of 4 weeks (1 month). When looking at developmental milestones over the first 2 years of life, some medical professionals look at a baby’s adjusted age instead of their actual age when assessing them.

Visit the AAP's web page on Premature Babies: Growth and Development for information on adjusting for prematurity.
