Infants born at 23 to 26 weeks' gestation are extremely underdeveloped and have a much higher risk of death or disability. Parents of these infants are likely to be faced with difficult medical decisions. Infants who have reached their 32nd week of development before birth are less at risk than those who are born earlier.
Babies born at 34 to almost 37 weeks' gestation are called late preterm infants. Although they are not as likely to have as many problems as infants who are born earlier, they are at risk for breathing problems, high blood pressure in the lungs, and other short-term and long-term problems.
