Premature babies are any babies born before the 37th week of a woman's pregnancy. However, if you've ever spent time inside a NICU, you know that preemies who are born at different stages of pregnancy are very different from one another! All premature babies are small, require complex medical care, and may face serious complications both in the NICU and at home. A baby born 3 to 4 months early, though, will face far different complications from a baby born 1 to 2 months early.
