How can I recognize normal newborn jaundice?

What newborn jaundice looks like

Newborn jaundice — yellowing of the skin and eyes caused by elevated bilirubin — is common and often harmless in the first week of life. It usually starts on the face and moves down toward the chest and limbs as bilirubin levels rise.

Typical features of normal jaundice:

• Appears between day 2 and 4 of life and often peaks around day 3–5.
• Baby is otherwise feeding well, producing wet and dirty diapers, and acting normally.
• Yellowing usually fades as bilirubin is processed by the liver over days to weeks.

When to seek medical attention

• Jaundice appearing within the first 24 hours of life.
• Rapidly increasing yellowing or spreading to the belly, arms, and legs.
• Poor feeding, lethargy, or very dark urine and pale stools.
• Any signs in babies born preterm or with blood type incompatibilities.

Assessment is typically by physical exam and, if needed, a bilirubin blood test. Treatment ranges from extra feedings and phototherapy to rarely exchange transfusion in severe cases. If you notice concerning yellowing or the baby seems unwell, contact your pediatrician promptly for evaluation.
