Preterm birth, also known as premature birth, is the birth of a baby at fewer than 37 weeks' gestational age.[1] These babies are known as preemies or premies.[1] Symptoms of preterm labor include uterine contractions which occur more often than every ten minutes or the leaking of fluid from the vagina.[8] Premature infants are at greater risk for cerebral palsy, delays in development, hearing problems and sight problems.[1] These risks are greater the earlier a baby is born.[1]
