Jaundice is a yellow coloring in your baby’s skin, and sometimes, the whites of the eyes. Newborn jaundice happens during the first weeks of life.

Babies with severe jaundice may need a blood transfusion. This will replace the baby’s blood with new blood. The excess bilirubin will be removed with the blood.
Newborn jaundice cannot always be prevented. The risk can be lowered by frequent feedings in the first several days after birth.
