When should the actual age of a preterm infant be used instead of their gestation-adjusted age?

Using the actual age of a preterm infant generally becomes appropriate after approximately 24 to 36 months. This timeframe is critical because by this age, many preterm infants have caught up developmentally to their full-term peers. Prior to this period, preterm infants may still exhibit developmental delays that relate to their preterm status, hence the need to use their gestation-adjusted age to provide a more accurate picture of their growth and developmental progress.

During the first two to three years, pediatricians and caregivers closely monitor these infants using adjusted age to account for the early birth and its effects. This means they focus on the developmental milestones that align more with their gestational age rather than their actual chronological age. By 24 to 36 months, many preterm infants show significant developmental progress, and the use of actual age reflects their capabilities more accurately. Thus, it allows for a more standard assessment and helps determine any ongoing needs or interventions.
