If you have just brought your newborn home and noticed a slight yellow tint to their skin or the whites of their eyes, you might feel a rush of concern. This yellowing is known as jaundice, and it is incredibly common, affecting more than half of all newborns in their first week of life. As you navigate those first few days of parenthood, you might find yourself wondering: is breastfeeding good for jaundice, or could it be making things more complicated?
At Milky Mama, we know how overwhelming those early days can be, especially when you are hit with medical terms and frequent pediatrician check-ups. If you need personalized guidance, our Certified Lactation Consultant Breastfeeding Help page is a supportive place to start. We are here to help you understand the relationship between nursing and jaundice so you can feel confident in how you feed your baby. This article will explore why jaundice happens, how breastfeeding supports your baby’s recovery, and what to do if your little one is too sleepy to nurse.
Breastfeeding is generally very good for babies with jaundice because it helps them clear bilirubin from their systems through frequent bowel movements. Understanding the "why" behind this process can help ease your mind and empower you to keep nursing through this common newborn hurdle.
To understand why breastfeeding is helpful, it is important to know what jaundice actually is. Jaundice is caused by an excess of bilirubin in the baby's blood. Bilirubin is a yellow pigment that is created when the body breaks down old red blood cells. Everyone has bilirubin, but newborns often have higher levels for a few reasons.
While a baby is in the womb, the mother’s liver handles the removal of bilirubin for the baby. Once the baby is born, their own liver has to take over the job. However, a newborn’s liver is often still immature and may take a few days to get up to speed. Additionally, newborns have more red blood cells than adults, and those cells break down faster, creating more bilirubin than their little livers can handle initially.
When the liver cannot process the bilirubin fast enough, it builds up in the blood and eventually settles in the skin and the whites of the eyes, giving them a yellow appearance. In most cases, this is called "physiologic jaundice," and it is considered a normal part of a baby adjusting to life outside the womb.
The short answer is yes. For the vast majority of babies, breastfeeding is the best way to help resolve jaundice. The reason is simple: bilirubin is primarily excreted from the body through stool (poop). The more your baby eats, the more they poop, and the more bilirubin they clear out of their system.
Early breast milk, called colostrum, acts as a natural laxative. Colostrum is the thick, golden milk your body produces in the first few days after birth. It is packed with antibodies and nutrients, but its laxative effect is particularly important for a jaundiced baby. It helps the baby pass their first stools, known as meconium. Meconium is often full of bilirubin, so getting it out of the body quickly prevents that bilirubin from being reabsorbed into the baby’s bloodstream.
Key Takeaway: Frequent breastfeeding provides the hydration and calories your baby needs to process bilirubin, while also stimulating the bowel movements necessary to flush it out of their system.
When a baby nurses frequently, it triggers a cycle that is very beneficial for clearing jaundice. First, the act of sucking stimulates the baby’s digestive tract. Second, the milk provides the energy the liver needs to function optimally.
It is also important to remember that hydration plays a role. While bilirubin is mostly excreted through poop, staying well-hydrated helps the baby’s overall metabolic processes. We often say that "every drop counts," and that is especially true when you are working to lower those bilirubin levels.
Not all jaundice is the same, and understanding the different types can help you talk to your pediatrician more effectively. While breastfeeding is generally good for all types, the management might look slightly different for each.
This is the most common type and usually appears around the second or third day of life. It peaks between days three and five and then begins to fade. For these babies, frequent nursing is usually all that is needed to help the body catch up.
Sometimes called "breastfeeding jaundice," this type occurs when a baby is not getting enough milk. This isn't because the breast milk itself is the problem, but rather because the baby isn't consuming enough volume to trigger those necessary bowel movements.
If a baby has a poor latch or if the mother’s supply is still establishing, the baby may become dehydrated and their bilirubin levels may rise. In these cases, the solution is usually to increase the frequency of feedings and read our Practical Solutions for What Helps With Low Milk Supply for more support.
This is a much rarer form of jaundice that typically shows up after the first week of life. It can last for several weeks or even a few months. Experts believe it may be caused by certain substances in breast milk that temporarily slow down the liver's ability to process bilirubin.
It is important to know that breast milk jaundice is rarely dangerous. Even if your baby stays a little yellow for a few weeks, as long as they are growing, hitting milestones, and their bilirubin levels stay within a safe range, you can usually continue breastfeeding without any issues.
One of the biggest challenges of breastfeeding a baby with jaundice is that high bilirubin levels can make babies very sleepy. This creates a difficult cycle: the baby needs to eat to clear the jaundice, but the jaundice makes them too tired to wake up and eat.
If your baby is jaundiced, you may need to be very proactive about feedings. Instead of waiting for the baby to cry (which is a late hunger cue), look for early signs like lip-smacking, rooting, or bringing their hands to their mouth. If your baby is sleeping through these cues, you will need to wake them up.
Here are some tips for waking a sleepy baby:
If you find that your baby is still struggling to stay awake or is not latching effectively, reach out for support early. You are doing an amazing job, but you don't have to navigate this alone.
In some cases, a pediatrician may recommend supplementation if a baby’s bilirubin levels are rising too quickly or if the baby is showing signs of dehydration. This can feel discouraging for a parent who wants to breastfeed exclusively, but it doesn't have to mean the end of your breastfeeding journey.
Supplementation should ideally be done with your own expressed breast milk first. If you need to supplement, using a breast pump can help you maintain your supply while ensuring your baby gets the extra volume they need. If you want a step-by-step approach, our guide to increasing milk supply with exclusive pumping can help you keep things moving.
Many families find that using a spoon, a small cup, or a syringe for supplementation can help avoid nipple confusion while the baby is still learning to latch. The goal is always to get the baby the nutrition they need to be healthy and then return to exclusive breastfeeding as soon as possible.
If bilirubin levels reach a certain threshold, the pediatrician may recommend phototherapy. This is a treatment where the baby is placed under special blue lights that help break down the bilirubin in the skin so it can be excreted more easily.
In the past, phototherapy often meant separating the mother and baby, which could be very stressful and disruptive to breastfeeding. However, modern medicine has made this much easier. Many hospitals now use "bili-blankets"—fiber optic blankets that wrap around the baby.
The beauty of a bili-blanket is that you can often continue to hold and nurse your baby while they are receiving treatment. If your baby needs the more traditional overhead lights, you should still be able to take them out for 20 to 30 minutes every few hours to breastfeed.

Action Steps for Phototherapy:
- Request a bili-blanket if possible to maximize skin-to-skin time.
- Ensure you are nursing at least 8 to 12 times in a 24-hour period.
- If the baby must stay under the lights, use that time to pump and build your "liquid gold" stash.
- Stay hydrated and nourished yourself to keep your energy up.
Managing a jaundiced newborn is physically and emotionally exhausting. You are likely dealing with extra blood draws for the baby, frequent weight checks, and the stress of a "sleepy feeder." This is a time when your own wellness is just as important as your baby's.
Maintaining your milk supply during these stressful early days is a common concern. Staying hydrated is one of the most important things you can do. Our Pumpin' Punch™ is designed to provide hydration along with lactation-supportive ingredients to help you feel your best. When you are well-hydrated, your body is better equipped to produce the milk your baby needs to clear that jaundice.
A second option is Lactation LeMOOnade™, which can also help you keep fluids up during the newborn haze.
In addition to hydration, nourishing snacks can give you the energy boost needed for those round-the-clock feedings. Our Emergency Lactation Brownies are a favorite among our community, providing a delicious way to incorporate oats and flaxseed into your diet.

Remember, breasts were literally created to feed human babies, and your body is doing something incredible. Even when things feel difficult, know that this phase is temporary. Most babies clear their jaundice within a week or two and go on to have very successful breastfeeding relationships.
Newborn jaundice can be a scary introduction to parenthood, but in most cases, it is a manageable condition that resolves with time and plenty of milk. Breastfeeding is not just safe for a jaundiced baby; it is often the very best medicine. By nursing frequently, monitoring your baby’s diaper output, and seeking help when you need it, you are giving your little one the best possible start.

Breastfeeding itself does not cause jaundice, but "suboptimal intake jaundice" can occur if a baby isn't getting enough milk to clear bilirubin through their stool. In contrast, "breast milk jaundice" is a rare, harmless condition where substances in the milk may cause jaundice to last longer, but it is not typically a reason to stop nursing.
You should aim to breastfeed your baby at least 8 to 12 times in a 24-hour period. Frequent feedings are essential because they stimulate bowel movements, which is the primary way your baby’s body removes bilirubin.
Yes, in most cases, you can and should continue to nurse your baby during phototherapy. If your baby is using a bili-blanket, you can usually nurse while they are wrapped in it; if they are under overhead lights, your doctor will typically allow you to take short breaks for breastfeeding.
Physiologic jaundice usually peaks around day three to five and clears up within one to two weeks. If your baby has breast milk jaundice, the yellow tint may persist for several weeks or even a few months, but it should be monitored by a pediatrician to ensure bilirubin levels remain safe.
