Newborn jaundice occurs in more than 60% of babies during their first week of life. It causes yellowing of the skin and whites of the eyes. Most cases are normal physiological jaundice, but sometimes treatment is needed. Here's what you need to know based on AAP 2022 guidelines!

What Is Newborn Jaundice?

Jaundice is yellowing of the skin and eyes due to high bilirubin levels in the blood.

What Is Bilirubin?

Yellow pigment produced when red blood cells break down
Newborns have shorter red blood cell lifespan, producing more bilirubin
Immature liver can't process bilirubin fast enough

Types of Jaundice

Physiological Jaundice (Normal)

Appears at 2-3 days old
Resolves within 1-2 weeks
Affects most newborns
No treatment needed

Pathological Jaundice (Needs Attention)

Appears within 24 hours of birth
Very high bilirubin levels
Lasts more than 2 weeks
May need treatment for underlying cause

How to Check for Jaundice

Visual Check

Observe in bright natural light
Gently press baby's forehead or nose
Check skin color when you release
Yellow color indicates possible jaundice

Progression Pattern

Jaundice typically spreads from top to bottom:

Face → Chest → Belly → Legs → Palms/Soles

If palms or soles are yellow, jaundice may be severe.

Risk Factors

Higher risk of severe jaundice:

Premature (before 35 weeks)
ABO blood type incompatibility (mom O, baby A or B)
Rh blood type incompatibility
Sibling treated with phototherapy
Cephalohematoma or significant bruising
Difficulty breastfeeding
East Asian ethnicity

Jaundice Treatment

Phototherapy

Special blue light breaks down bilirubin
Can be done in hospital or at home
Eye protection required
Safe and effective treatment

Exchange Transfusion

Only for severe cases
Replaces baby's blood with donor blood
Rarely needed

What You Can Do at Home

Frequent feeding (8-12 times daily)
Ensure feeding is going well
Check diaper count (signs of adequate intake)
Sun exposure is NOT recommended (ineffective and risky)

Breastfeeding and Jaundice

Breastfeeding Jaundice

Occurs when feeding is insufficient
Solution: Feed more frequently

Breast Milk Jaundice

Starts at 1-2 weeks
Caused by substances in breast milk
Usually harmless, continue breastfeeding
May last weeks to months

💡 Don't stop breastfeeding because of jaundice! More frequent feeding actually helps.

When to See a Doctor

Seek immediate care if:

Jaundice appears within 24 hours of birth
Jaundice spreads to palms/soles
Baby is limp or lethargic
High-pitched crying
Arched neck
Refuses to feed or feeds poorly
Fever present
Jaundice lasts over 2 weeks (full-term) or 3 weeks (preterm)

Long-Term Effects

In Most Cases

Normal development
No lasting effects

If Severe Jaundice Untreated (Rare)

Kernicterus (brain damage)
Hearing loss
Cerebral palsy

→ Early detection and treatment is key!
