My baby is 7days old and his eyes are yellow. please wats happening? hope it's not a serious issue?

Not uncommon: Neonatal jaundice occurs in some newborns; usually resolves with time or more rapidly with light therapy. Tends to develop because of 2 factors - breakdown of fetal hemoglobin as it is replaced w/ adult hemoglobin & the relatively immature liver metabolic pathways that can't conjugate & excrete bilirubin as quickly as an adult. Discuss with pediatrician for more reassurance.

Icterus: Take your baby to the doctor immediately. This is jaundice and needs to be treated promptly at his age.
