Seeing milk come out of your newborn's nose can be a startling and worrying sight for any parent. It's completely normal to feel concerned when you encounter something unexpected with your little one. However, rest assured that this occurrence, known as nasal regurgitation, is quite common in newborns.
Research shows that up to 67% of healthy infants experience regurgitation in their first three months, and sometimes, this can involve milk coming out through the nose (Epidemiology and Management of Gastro-oesophageal Reflux in Children).
At Mamazing, we understand the anxieties and questions that new parents face. That's why we've put together this detailed guide to explain why this happens, when you should seek medical advice, and how you can manage and prevent it. Our goal is to equip you with the information and confidence to handle this situation calmly, ensuring your baby receives the best possible care.
What Is Nasal Regurgitation?
Nasal regurgitation, also known as nasal reflux, is when milk or formula exits through a newborn’s nose during or after feeding. This phenomenon, while surprising to parents, is quite common in infants due to their unique anatomical and developmental characteristics. In newborns, the nasal and oral cavities are closely connected, with a short distance between the back of the throat (nasopharynx) and the nasal passages. This proximity makes it easier for milk to enter the nose, especially if feeding conditions are not optimal.
The primary reason for nasal regurgitation lies in the immaturity of a newborn’s digestive system. The lower esophageal sphincter, a ring-like muscle that controls the flow of milk from the esophagus into the stomach, is not fully developed in infants. This immaturity can allow milk to flow back up into the esophagus—a process known as reflux—and sometimes exit through the nose, particularly if the baby is lying flat, has swallowed air, or is fed too quickly. Research suggests that this is a normal part of infancy, with up to 67% of healthy infants experiencing regurgitation, some of which may involve the nose, in their first three months (Gastroesophageal Reflux in Children: An Updated Review).
Additionally, newborns are still mastering the complex coordination of sucking, swallowing, and breathing during feeding. This process requires precise timing, and until it is fully developed, milk can occasionally take an unexpected route through the nasal passages. For example, if a baby swallows too much air or milk flows too quickly, it may overwhelm their ability to manage the intake, leading to nasal regurgitation.
It’s important to emphasize that nasal regurgitation is typically harmless and does not cause discomfort to the baby in most cases. As the digestive system matures and feeding coordination improves, usually by 12 to 18 months, these incidents naturally decrease and often stop entirely. However, parents should stay observant and consult a pediatrician if the regurgitation is frequent, persistent, or accompanied by signs of distress, as these could indicate an underlying issue that needs attention.

Is It Normal and When to Seek Medical Advice
Seeing milk come out of your newborn’s nose can be unsettling, but rest assured, this phenomenon, known as nasal regurgitation, is typically normal and common in infants.
Research suggests that up to 67% of healthy infants experience regurgitation at least once in their first three months, and in some cases, this milk may exit through the nose due to the close connection between the nasal and oral cavities (Twiniversity). This usually happens because a newborn’s digestive system is still developing, with muscles like the lower esophageal sphincter not yet fully matured, allowing milk to flow back up more easily.
In most cases, nasal regurgitation is harmless and does not cause discomfort to your baby. It’s a natural part of infancy as babies learn to coordinate sucking, swallowing, and breathing during feeding. The issue often peaks around 3 to 4 months and typically resolves on its own by 12 to 18 months as the digestive system strengthens and feeding skills improve (Gastroesophageal Reflux in Children). For many parents, this is simply a messy but normal part of caring for a newborn, often requiring just a quick wipe with a soft cloth and some extra cuddles.
When to Consult a Pediatrician?
However, there are situations where nasal regurgitation may warrant a closer look. You should consult your pediatrician if you notice any of the following:
In rare cases, persistent nasal regurgitation could signal an underlying condition, such as a cleft palate, which may not have been detected at birth, or gastroesophageal reflux disease (GERD), a more severe form of reflux that might cause discomfort or complications (LactApp). For example, a cleft palate can create a direct connection between the mouth and nasal passages, leading to frequent milk leakage through the nose. If you suspect an underlying issue or if your baby seems to struggle with feeding or breathing, seek medical advice promptly.
Every baby is unique, and what’s normal for one may not be for another. If you’re ever uncertain or worried about your baby’s health, don’t hesitate to contact your pediatrician for personalized guidance. They can assess your baby’s condition, check for any underlying issues, and provide reassurance or treatment as needed. At Mamazing.com, we’ve consulted pediatricians and parenting experts to ensure this advice is reliable and supportive, helping you navigate this common yet surprising aspect of newborn care with confidence.
Common Causes of Milk Coming Out of the Nose
As a new parent, noticing milk coming out of your newborn’s nose can feel alarming, but it’s often due to common, harmless reasons tied to their developing body or feeding habits. Understanding these causes can help you take simple steps to reduce how often it happens and ensure your baby stays comfortable during feedings. Below, we explore the most frequent reasons why milk might exit through your baby’s nose, based on expert insights and research.
Immature Digestive System
A newborn’s digestive system is still maturing, which plays a significant role in nasal regurgitation. The lower esophageal sphincter (LES), a muscle that acts like a valve between the esophagus and stomach, is not fully developed in infants. In adults, the LES prevents stomach contents from flowing back up, but in newborns, its weakness allows milk to reflux into the esophagus. Because the throat and nasal passages are closely connected in babies, this refluxed milk can sometimes exit through the nose. The epiglottis, a flap that directs food away from the airway, is also less developed, further contributing to this issue. As noted by LactApp, “Babies have immature parts of their digestive system. In some cases, the muscles and valves that control milk flow down the throat and prevent it from entering the nose are not yet fully developed.”
Overfeeding or Feeding Too Quickly
Feeding your baby too much milk or too quickly can overwhelm their small stomach, leading to regurgitation. Newborns have tiny stomachs—about the size of a cherry at birth—and can only handle small amounts at a time. If milk flows too fast, such as during a strong breastfeeding let-down or with a fast-flow bottle nipple, it can cause the stomach to push milk back up, sometimes through the nose. Recognizing your baby’s fullness cues, like turning away or closing their mouth, can help prevent overfeeding. Twiniversity advises, “When bottle feeding, it is common for babies to eat too fast or too much at once. Look into paced feeding, a technique that can help bottle-fed babies eat more slowly and reduce reflux.”
Incorrect Feeding Positions
The position in which you feed your baby can influence whether milk comes out of their nose.
Feeding while lying flat, such as in a cradle hold on their back, allows milk to pool in the throat, increasing the chance it will flow into the nasal passages. In contrast, feeding in an upright position, such as at a 45-degree angle, helps gravity keep milk in the stomach. Babynama recommends, “Feed in an Upright Position: Hold your baby in an upright position while feeding to help gravity guide the milk down to the stomach.” Simple adjustments, like holding your baby more vertically, can make a big difference.
Swallowing Air
During feeding, babies can swallow air, especially if they have a poor latch while breastfeeding or if the bottle isn’t angled correctly to keep the nipple filled with milk. This swallowed air creates gas bubbles in the stomach, which can push milk back up the esophagus and out through the nose, particularly if the baby is lying flat. A proper latch during breastfeeding, where the baby takes in most of the areola, and careful bottle positioning can reduce air intake. Momcozy notes, “If milk flows in too quickly, or they swallow too much air, milk can come out through the nose.”
Medical Conditions
In rare cases, medical conditions can cause milk to come out of a newborn’s nose. A cleft palate, for instance, creates an opening between the mouth and nasal cavity, allowing milk to pass directly into the nose during feeding. Tongue-tie, where a tight band of tissue restricts tongue movement, can make latching difficult, leading to increased air swallowing and potential regurgitation. These conditions are uncommon but should be considered if nasal regurgitation is frequent or severe. The CDC explains, “In infants born with a cleft lip and/or a cleft palate, the oral cavity may not be adequately separated from the nasal cavity during feeding, which can make it difficult to create the suction needed to breastfeed successfully. Other difficulties may include nasal regurgitation.”
By understanding these common causes, you can take proactive steps to minimize nasal regurgitation and create a more comfortable feeding experience for your baby. The next section summarizes these causes for quick reference, followed by practical strategies to manage and prevent this issue.
How to Prevent and Manage Nasal Regurgitation
While nasal regurgitation, or milk coming out of your newborn’s nose, is typically a normal part of infancy that resolves as your baby grows, there are practical steps you can take to reduce its frequency and keep your baby comfortable during feedings. By adjusting feeding techniques, being mindful of your baby’s needs, and responding calmly if it happens, you can make feeding a more pleasant experience for both of you. Below, we outline evidence-based strategies to prevent and manage nasal regurgitation, drawing on insights from pediatricians, lactation consultants, and reputable parenting resources.
Prevention Strategies
Implementing these techniques during feeding can significantly reduce the likelihood of milk coming out of your newborn’s nose. These strategies address the common causes, such as swallowed air, fast milk flow, and improper positioning, to create a smoother feeding experience.
Feed in an Upright Position
Holding your baby in an upright position during and after feeding helps gravity keep milk in the stomach, reducing the chance of reflux into the nasal passages. Aim for a 45-degree angle or more, ensuring the baby’s head is higher than their stomach. For breastfeeding, try positions like the football hold or a diagonal cradle hold, where the baby is elevated. For bottle-feeding, hold your baby semi-upright rather than lying flat. Keeping your baby upright for 15–30 minutes after feeding can further prevent regurgitation. According to the Cleveland Clinic, “Keeping babies upright during and after feeding can minimize reflux.”
Burp Frequently
Frequent burping during and after feeds releases trapped air in the stomach, which can otherwise push milk back up and out through the nose. For babies prone to reflux or nasal regurgitation, burp every 2–3 ounces during bottle-feeding or every 5 minutes during breastfeeding. Effective burping positions include:
-
Over the Shoulder: Hold your baby upright with their chin resting on your shoulder, supporting their head and neck. Gently pat or rub their back with a cupped hand.
-
Sitting on Lap: Sit your baby on your lap, facing away from you, supporting their chest and chin (avoiding the throat). Gently pat or rub their back.
-
Lying Across Lap: Lay your baby face-down across your lap, supporting their head slightly higher than their chest, and gently pat their back.
The American Academy of Pediatrics recommends, “Gently pat or rub their back with your other hand” to release air effectively. For babies with reflux, burping more often, such as every ounce during bottle-feeding, can be particularly helpful (Philips Avent).
Avoid Overfeeding
Newborns have tiny stomachs—about the size of a cherry at birth—and overfeeding can overwhelm them, leading to regurgitation. Pay attention to your baby’s hunger and fullness cues to avoid giving too much milk. Hunger cues include rooting, sucking on hands, or opening the mouth, while fullness cues include turning away, closing the mouth, or relaxing hands. Offering smaller, more frequent feeds can prevent stomach overload. [A Date With Baby]([invalid url, do not cite]) advises, “Avoid overfeeding your baby. Sometimes the baby can act full, even if you know that he has actually eaten less. When this happens, trust his instincts and never force them to feed more than they need.”
Breastfeeding-Specific Tips
For breastfeeding mothers, a strong or overactive let-down can cause milk to flow too quickly, overwhelming your baby and increasing the risk of nasal regurgitation. To manage this:
-
Express Milk Before Feeding: Manually express or pump a small amount of milk before starting to feed to reduce the initial forceful flow. Catch the milk in a cloth or container to avoid waste.
-
Use a Laid-Back Position: Nurse in a reclined or laid-back position, with your baby lying on top of you. This allows gravity to slow the milk flow, making it easier for your baby to manage. Breastfeeding Support notes, “In a laid-back position, the baby is positioned on top of the breast, so gravity assists in making the let-down less forceful.”
-
Allow Breaks: If your baby seems overwhelmed, let them come off the breast during a strong let-down, catch the fast spray in a cloth, and re-latch them once the flow slows.
-
Work with a Lactation Consultant: If a strong let-down or oversupply persists, a lactation consultant can help adjust your milk production or feeding techniques.
These strategies can help your baby handle milk flow better, reducing the chance of milk coming out of their nose (La Leche League Canada).
Bottle-Feeding Tips
For bottle-fed babies, the bottle and feeding technique can influence regurgitation. To minimize nasal regurgitation:
-
Use Slow-Flow Nipples: Choose bottles with slow-flow nipples to control the milk flow, preventing your baby from taking in too much too quickly. Ready, Set, Food! recommends, “Your baby’s bottle should have a smaller, slow-flow nipple to prevent overfilling of baby’s stomach.”
-
Proper Bottle Angle: Hold the bottle at an angle so the nipple is always filled with milk, not air, to reduce air swallowing. NHS Start for Life advises, “Check that the hole in your baby’s teat is not too big. Drinking milk too quickly can make your baby sick.”
-
Paced Feeding: Mimic breastfeeding by pausing every few sucks to allow your baby to rest and breathe. Hold the bottle horizontally and tip it slightly, letting your baby control the pace. Cork Children’s Clinic explains, “Paced feeding helps baby control the flow of milk better.”
-
Consider Anti-Reflux Formula: If regurgitation persists, consult your pediatrician about using a thicker formula designed to reduce reflux, as suggested by NHS.
These adjustments can help ensure a smoother feeding experience and reduce the likelihood of milk exiting through the nose.
Management Strategies
If milk does come out of your baby’s nose, it’s important to respond calmly and effectively to keep both you and your baby comfortable:
-
Stay Calm and Reassure Your Baby: Nasal regurgitation can startle your baby, so maintain a calm demeanor and offer soothing words or gentle pats to comfort them. [Momcozy]([invalid url, do not cite]) suggests, “Spitting up through the nose can startle your baby, so comfort them with gentle pats or soothing words.”
-
Gently Clean the Nose: Use a soft, clean cloth or tissue to wipe away any milk from the nostrils to prevent irritation. If milk remains in the nose, you can use a bulb syringe to gently clear it, but avoid overuse to prevent discomfort. [Momcozy]([invalid url, do not cite]) recommends, “Gently clear any residual from the nostrils with a soft tissue or a bulb syringe.”
-
Hold Upright and Pat Gently: After an episode, hold your baby upright and gently pat their back to help clear any milk from their airways and settle their stomach. This can also prevent further regurgitation.
Additional Considerations
These strategies are generally effective for most babies, but every infant is unique. If you’ve tried these adjustments and nasal regurgitation remains frequent or your baby shows signs of distress, revisit the guidance in our earlier section on when to seek medical advice. A pediatrician or lactation consultant can provide personalized recommendations, such as checking for issues like tongue-tie or adjusting formula types.
By combining these prevention and management techniques, you can create a more comfortable feeding experience for your baby and reduce the worry associated with milk coming out of their nose.
Expert Advice
When it comes to understanding and managing nasal regurgitation in newborns, expert insights from pediatricians and medical organizations provide valuable guidance and reassurance. According to the American Academy of Family Physicians, regurgitation in infants, which can include milk coming out of the nose, is a normal physiological process that typically resolves by 12 months of age. For most cases, no treatment is necessary as long as the baby is healthy and growing well. The American Academy of Pediatrics also notes that occasional spit-up is common and usually doesn't require medical intervention.
However, if nasal regurgitation is frequent or accompanied by symptoms such as poor weight gain, distress, or unusual spit-up (e.g., green or bloody), it’s
important to consult a pediatrician to rule out underlying conditions like gastroesophageal reflux disease (GERD) or structural issues such as a cleft palate. The CDC highlights that conditions like cleft palate can cause nasal regurgitation due to the direct connection between the mouth and nasal cavity.
Lactation consultants and pediatricians recommend several strategies to reduce the occurrence of nasal regurgitation:
-
Feeding in an Upright Position: This helps gravity keep milk in the stomach.
-
Frequent Burping: Releasing trapped air reduces the likelihood of milk being pushed back up.
-
Avoiding Overfeeding: Recognizing fullness cues prevents stomach overload.
-
Proper Latching and Bottle Techniques: Ensuring a good latch or using slow-flow nipples minimizes air swallowing.
These expert-recommended techniques align with the natural development of a baby’s digestive system and help ensure comfortable feedings (La Leche League).
