A premature baby is one who is born too early, before 37 weeks. Premature babies may have more health problems and may need to stay in the hospital longer than babies born later. They also may have long-term health problems that can affect their whole lives. About 1 in 10 babies is born prematurely each year in the United States.
Babies should be considered premature even if they are born after 38 weeks, experts claimed yesterday. Up to now, babies were defined as âfull termâ if they were born anytime from 37 to 42 weeks in the womb. They were only regarded as premature if they were born before the 37-week mark. But American doctors believe the ideal pregnancy is two weeks longer.
