Learn about jaundice baby, its causes, signs, treatments, and tips to keep your newborn healthy.
Introduction
Having a new baby is exciting, but it can bring health worries too. Many newborns get jaundice, a condition that makes their skin and eyes look yellow. It happens in about 60% of full-term babies and 80% of premature ones. Most cases are mild and go away in a week or two. Knowing the basics helps parents decide when to call a doctor.
This guide explains why babies get jaundice, how to spot it, ways to treat it, and tips for home care. Whether you’re a new parent or want to learn more, this article gives clear, simple advice to help you feel confident.
What is Jaundice in Babies?
Jaundice in newborns happens when a yellow substance called bilirubin builds up in the blood. Bilirubin comes from breaking down old red blood cells. In adults, the liver clears it out fast. But a newborn’s liver is still growing, so it works slowly, causing yellow skin and eyes.
This is common because babies have more red blood cells, and these break down quickly. Their livers need time to catch up. Most jaundice starts on day two or three and peaks by day five. It’s not a sickness but a normal phase for many babies.
Bilirubin levels in newborns often reach 5-10 mg/dL in the first days. Higher levels may need a doctor’s check. In darker-skinned babies, yellow skin is harder to see, so look at the eyes, gums, or tongue.
This phase is just part of a baby adjusting to life outside the womb.
Causes of Jaundice Baby
Jaundice comes from too much bilirubin, but different things can cause it. Here’s a simple breakdown.
Most babies get physiological jaundice because their livers are still learning to process bilirubin. Newborns make more bilirubin than adults since they have extra red blood cells that break down fast.
Breastfeeding can sometimes play a role. If a baby doesn’t get enough milk in the first week, maybe due to latching issues, they may get dehydrated. This means less bilirubin leaves through poop. Another type, breast milk jaundice, starts later and may last a month. It’s usually mild and tied to something in the mother’s milk.
Serious causes include blood type differences, like when a mom’s blood is type O and the baby’s is A or B, or Rh mismatches. This makes the baby’s red blood cells break down faster. Infections, birth bruises, or conditions like G6PD deficiency (common in some groups) can also raise bilirubin. Rarely, liver issues like blocked bile ducts cause it.
Premature babies are more likely to get jaundice since their livers are less ready. Genetic issues or low thyroid levels can also contribute.
Knowing the cause matters because some types need quick care, while most are harmless.
Signs to Watch for in Newborn Jaundice
Spotting jaundice early helps keep your baby safe. The main sign is yellow skin, starting on the face and moving to the chest, belly, arms, and legs. The eyes’ whites may look yellow too.
Check by pressing your baby’s forehead or nose in good light. If the skin looks yellow, it might be jaundice. For darker-skinned babies, check palms, soles, or inside the mouth.
Other signs include being sleepy, not feeding well, having few wet diapers, dark pee, or pale poop. In rare cases, look for a high-pitched cry, arched back, fever, or seizures—these need urgent care.
Jaundice often peaks on days three to five, so watch closely then. Call a doctor if it starts before 24 hours or gets worse.
Diagnosing Jaundice in Newborns
Doctors check for jaundice before babies leave the hospital. They look at the skin and may use a skin meter to guess bilirubin levels without a needle.
If levels seem high, a small blood test from the heel checks the exact amount. Doctors use a chart to see if the level is normal for the baby’s age. For example, over 15 mg/dL at 48 hours may need treatment.
Other tests, like blood type checks or infection screenings, find causes if needed. For long-lasting jaundice, doctors might do ultrasounds or liver tests.
Early checks stop problems, and most hospitals test all babies before they go home.
Treating Jaundice in Babies
Most jaundice goes away on its own as the liver grows stronger. But if bilirubin is too high, treatment helps.
The main treatment is phototherapy, where babies sit under blue lights that change bilirubin so it leaves the body in pee or poop. Babies wear diapers and eye covers, and it takes one or two days, either in the hospital or at home with a special blanket.
For breastfeeding issues, feed more often or add formula for a bit to help the baby poop more. If blood type issues cause jaundice, a medicine called IVIg can slow red blood cell damage.
In rare cases, severe jaundice needs a blood transfusion to lower bilirubin fast. Treatment depends on the baby’s age, weight, and health.
Always listen to your doctor. Don’t try things like sunlight, which can burn your baby.
Home Care for Jaundice Baby
At home, focus on feeding and watching your baby. Breastfeed 8-12 times a day to keep them hydrated and help bilirubin leave through poop. Formula-fed babies need 1-2 ounces every 2-3 hours.
Check for at least 6 wet diapers and 3-4 poopy ones by day four. Weigh your baby to ensure they’re gaining weight. Losing too much weight can make jaundice worse.
Go to all doctor visits, especially on days 3-5 when jaundice peaks. Keep a log of skin color or behavior changes. If using home light therapy, follow the doctor’s rules.
Tummy time and cuddles help, but don’t use over-the-counter treatments without asking a doctor.
Risks and Complications of Jaundice
Some babies have a higher chance of strong jaundice. Premature babies (born before 37 weeks) have weaker livers. Bruises from birth, blood type issues, or family history raise the risk. Babies with Down syndrome or certain ethnic backgrounds, like East Asian or Mediterranean, may face issues like G6PD deficiency.
If bilirubin gets too high, it can cause brain issues called bilirubin encephalopathy, with signs like sleepiness or not eating. Rarely, it leads to kernicterus, which can harm hearing, movement, or teeth. Good care makes these rare.
Preventing Jaundice in Babies
You can’t always stop jaundice, but you can lower its strength. Feed your baby often from day one—breastfeed whenever they want or stick to formula schedules. Prenatal tests can spot blood type issues early, and shots like Rhogam help for Rh-negative moms.
Watch for early signs and go to all check-ups. If breastfeeding, get help to make sure your baby feeds well.
A healthy pregnancy and avoiding infections also lower risks.
Myths and Facts about Jaundice Baby
Myth: Jaundice means the liver is sick.
Fact: Most cases come from a normal, growing liver, not disease.
Myth: Sunlight fixes jaundice.
Fact: A little sun might help, but it’s risky and not as good as doctor-approved light therapy.
Myth: Stop breastfeeding if jaundice happens.
Fact: Keep breastfeeding—it’s good for your baby, and feeding issues can be fixed.
Fact: Jaundice might happen again in siblings, so tell your doctor about family history.

Too much bilirubin from breaking down red blood cells, plus a young liver. Breastfeeding issues or blood type differences can also cause it.
How long does jaundice last?
Mild cases clear in 1-2 weeks. Breast milk jaundice may last a month. Long cases need a doctor.
When should I worry about jaundice?
Call a doctor if it starts before 24 hours, gets worse after day 5, spreads to arms/legs, or if your baby is sleepy, not eating, or has dark pee/pale poop.
Is light therapy safe?
Yes, it’s safe with eye protection. Side effects like loose poop or rash don’t last.
