Question: how common is jaundice in newborn babies?
Answer: Jaundice is 1 of the most common conditions that can affect newborn babies. It's estimated 6 out of every 10 babies develop jaundice, including 8 out of 10 babies born prematurely before the 37th week of pregnancy. But only around 1 in 20 babies has a blood bilirubin level high enough to need treatment.
