Infant jaundice is yellow discoloration of a newborn baby’s skin and eyes. Infant jaundice occurs because the baby’s blood contains an excess of bilirubin (bil-ih-ROO-bin), a yellow pigment of red blood cells.
Infant jaundice is a common condition, particularly in babies born before 38 weeks’ gestation (preterm babies) and some breastfed babies. Infant jaundice usually occurs because a baby’s liver isn’t mature enough to get rid of bilirubin in the bloodstream. In some babies, an underlying disease may cause infant jaundice.
