What term is used for a baby born after the 37th week of gestation?

The term used for a baby born after the 37th week of gestation is "term infant." This classification indicates that the infant has completed the necessary gestational age for a full term pregnancy, typically defined as lasting from 37 weeks to 42 weeks. Delivery during this period is essential because it signifies that the baby has developed to a stage where they are more likely to thrive outside the womb with fewer complications associated with prematurity.

In contrast, the term "preterm infant" refers to babies born before 37 weeks of gestation, which can lead to various health challenges as their organs and systems may not be fully developed. "Neonatal" describes the period right after birth, spanning from birth to 28 days of life, but does not specify gestational age. The term "post-term infant" is used for babies who are born after 42 weeks of gestation, a different classification that can carry specific risks due to being overdue. Thus, "term infant" appropriately indicates the ideal range for neonatal health and development.
