Newborn Jaundice — What Is Common and When It Needs Checking
Jaundice makes the skin or eyes look yellow and is common after birth, but timing, level, feeding and the baby’s condition determine whether testing or treatment is needed.
Updated:
Why it happens
Bilirubin is produced as red blood cells break down. Newborn livers take time to process it, so levels can rise after birth.
How it is assessed
Clinicians consider the baby’s age in hours, gestation, feeding, risk factors and a measured bilirubin level. Looking alone cannot determine severity.

Common questions
Does sunlight treat newborn jaundice?
Do not use direct sunlight as treatment. Babies who need treatment receive measured clinical care such as phototherapy.
