​​​​​​​​​​​​​​​​​”Full Term” Has a New Meaning

The meaning of “term” pregnancy has changed. “Term” has been replaced by more specific definitions that communicate the importance of the last few weeks of pregnancy for infant development. Learn why the term pregnancy definitions are important to promoting the best outcomes for mom and baby.

“Full Term” Starts at 39 Weeks

The American College of Obstetricians and Gynecologists and the Society for Maternal Fetal Medicine announced more specific definitions to describe babies born between 37 weeks and 42 weeks of pregnancy. In the past, a baby born anytime between 37 weeks and 42 weeks was considered “term.” A pregnancy is now considered “full term” at 39 weeks.
