A neonate is a baby who is 4 weeks old or younger.
A neonate is also called a newborn. The neonatal period is the first 4 weeks of a child's life. It is a time when changes are very rapid. Many critical events can occur in this period:
- Feeding patterns are established.
- Bonding between parents and infant begin.
- The risk for infections that may become more serious are higher.
- Many birth or congenital defects are first noted.
