My doc. says my 3 days old girl has signs of jaundice & kept under some kind of blue light & breastfeeding. bilirubin level is 16..should i worry?

Reason for jaundice?: This would make the big difference. Since we know that physiologic jaundice will increase the total load up to day number 5 on a full term baby. It is a good idea to keep the baby until bilirubin stops climbing under phototherapy. If the baby is acting healthy and eating good and having good bowel movements as long as there is no blood incompatibility seriousness goes down.
