Understanding Newborn Jaundice: What Parents Need to Know

Introduction:
You bring your baby home and notice their skin and eyes turning yellow. Panic? Not quite. This could be newborn jaundice, and while it sounds scary, it’s often harmless and very common in newborns.

🔍 What is Jaundice in Newborns?

Aspect

Details

Definition

Yellowing of the skin and eyes due to excess bilirubin in the blood.

Caused by

Immature liver not yet fully efficient in breaking down bilirubin.

Common Timeline

Usually appears on day 2–3 of life, peaks by day 5, and fades by 2 weeks.

 

🧪 What is Bilirubin?

Term

Meaning

Bilirubin

A yellow pigment produced during the breakdown of red blood cells.

Why it increases

Babies are born with extra red blood cells that break down quickly.

Liver's role

Liver filters and removes bilirubin—but in newborns, this process is slow.

 

⚠️ When to Worry? Normal vs. Concerning

Type of Jaundice

Is It Normal?

What It Means

Physiological Jaundice

Yes ✅

Most common. Harmless. Resolves on its own.

Breastfeeding Jaundice

Yes, sometimes

Happens when baby isn’t feeding well, leading to dehydration.

Breast Milk Jaundice

Yes, mild cases

Some breast milk slows bilirubin breakdown. Often harmless.

Pathological Jaundice

No 🚨

Appears <24 hrs after birth or is very intense. Needs medical attention.

 

🔍 Symptoms Checklist

Look For

Details

Yellowing of skin and eyes

Start from face, move to chest and legs.

Poor feeding

Baby feeds less or is unusually sleepy.

Dark yellow urine

Should be light in newborns.

Pale stool (grey or chalky)

Warning sign—get immediate help.

 

🏥 How Jaundice is Diagnosed

Method

Details

Physical exam

Pediatrician examines skin and eyes.

Skin scanner (bilirubin meter)

Non-invasive check of bilirubin level.

Blood test (TSB test)

Measures actual bilirubin level. May be repeated over days.

 

✅ Home Care & Monitoring Tips

Action

Why It Helps

Feed frequently (every 2–3 hrs)

Hydration helps flush out bilirubin via urine and stools.

Sunlight exposure (indirect)

Natural light can help break down bilirubin through skin.

Track symptoms daily

Take photos to track yellowing—share with pediatrician if unsure.

 

🩺 When is Treatment Needed?

Treatment Option

Used When

Phototherapy

Blue light helps break down bilirubin. Common and safe.

Supplemental feeding

If baby isn’t nursing enough or needs extra hydration.

IV fluids or exchange transfusion

Very rare. Used in high-risk or severe cases.

 

✍️ A Relatable Note from a New Mom:

“When my baby turned yellow on day 3, I was terrified. But my pediatrician calmly explained it was physiological jaundice. We just had to feed her more often, and keep her in a sunny room during the day. By the end of the week, the yellow faded—just like he said it would.”

🧡 Final Words:

Jaundice is common—affecting nearly 60% of full-term and 80% of preterm babies. In most cases, it resolves naturally. The key is to monitor it closely, act fast if symptoms worsen, and always keep in touch with your pediatrician.
