How to reduce the risk of jaundice in newborns; what to do if they've got it already - Indiatimes.com

According to Neymours KidsHealth, newborns usually have physiological jaundice because they are born with more blood cells than an adult. The blood cells do not survive for long and break down causing more bilirubin in the body. The baby can develop this kind of jaundice 2-4 days after being born. However, he/she recovers when they're 2 weeks old.

But in most cases, babies are likely to develop jaundice if they were either born prematurely or are not breastfed regularly. It could also occur if the baby's blood type does not match the mother's.

In addition, if the baby has a genetic problem that makes red blood cells more fragile or is born with high red blood cell numbers.
