Classification on gestational age
A premature baby is a baby born before 37 completed weeks of pregnancy. Based on the gestational age, preterm babies are further classified as follows:
Preterm baby: Babies born between the gestational ages of 32-36 weeks of gestation, as calculated from the mother's last normal menstrual period (LNMP date). These babies can usually be managed safely at home with some extra care and support, which you will learn later in this study session.
Very preterm baby: Babies born between the gestational ages of 28-31 weeks as calculated from the LNMP date. Like very low birth weight babies and for the same reasons, they have problems in feeding and maintaining their body temperature. If possible, they should be referred urgently for specialist care at a hospital.
