Milk Coming Out of Baby’s Nose
Table of Contents
As a new parent, seeing milk come out of your baby’s nose can be a surprising—and sometimes unsettling—experience. You may wonder if something is wrong, if your baby is choking, or if this is a normal part of development. The good news? In many cases, it’s a common and harmless occurrence. Still, understanding why it happens and when it might be a sign of something more serious is crucial.
This article dives deep into everything you need to know about milk coming out of baby’s nose—why it happens, how to prevent it, when to worry, and how it ties into related feeding and digestive concerns like spitting up and baby acne caused by breast milk.
What Does It Mean When Milk Comes Out of Baby’s Nose?
Milk coming out of a baby’s nose is medically referred to as nasal regurgitation. This happens when milk flows back up the esophagus and escapes through the nasal passages instead of staying in the stomach where it belongs. It might look scary, especially for first-time parents, but it’s typically caused by the baby’s underdeveloped digestive system.
How It Happens
Milk Coming Out of Baby’s Nose : When babies feed, either from the breast or bottle, the milk travels down their esophagus to the stomach. Sometimes, the muscles that keep the milk in the stomach (called the lower esophageal sphincter) are still immature. This can cause the milk to flow back up—what we often refer to as “spit-up.” Because the nose and throat are connected through the back of the throat (the nasopharynx), some milk can come out of the nose.
Common Causes of Milk Coming Out of Baby’s Nose
Understanding why this happens helps you react appropriately. Here are the most common reasons:
1. Immature Digestive System
Most newborns and infants have underdeveloped digestive tracts. Their esophageal muscles may not close tightly after feeding, causing milk to come back up. This is the most frequent cause of nasal milk regurgitation.
2. Overfeeding
Feeding too much or too quickly can overwhelm your baby’s tiny stomach. When it’s too full, milk may be expelled through both the mouth and nose.
3. Fast Letdown or Nipple Flow
If you’re breastfeeding and have a fast milk letdown, or if you’re using a bottle with a fast-flow nipple, your baby might take in more milk than they can swallow, resulting in overflow.
4. Feeding While Lying Flat
Feeding your baby while they are lying on their back may make it easier for milk to travel the wrong way—especially if they’re sleepy and not actively swallowing.
5. Laughing or Coughing During Feeding
Sometimes babies get playful, especially as they grow older. Laughing, hiccupping, or coughing during feeding can interrupt swallowing and result in milk going “up the wrong pipe.”
6. Nasal Reflux From Spit-Up
Sometimes the milk that’s spit up finds its way into the nasal passages by sheer gravity or pressure from the baby’s body posture.
Is It Dangerous?
In most cases, milk coming out of baby’s nose is not dangerous. However, if it happens very frequently, or if your baby shows signs of distress, choking, or slow weight gain, it may be a sign of an underlying issue such as gastroesophageal reflux disease (GERD), milk protein allergy, or a structural abnormality like a cleft palate.

- Your baby seems comfortable afterward
- It doesn’t happen at every feeding
- There’s no crying or signs of pain
- Baby is growing and gaining weight well
Milk Coming Out of Baby’s Nose : When to See a Pediatrician
Not every incident warrants a trip to the doctor, but the following signs may indicate something more serious:
| Symptom | What It Might Indicate |
|---|---|
| Persistent regurgitation through nose | GERD or esophageal abnormality |
| Baby turns blue or seems to struggle | Possible aspiration |
| Poor weight gain | Digestive absorption issue |
| Blood in regurgitated milk | GI bleeding or severe reflux |
| Nasal congestion after each feed | Milk in nasal passage causing irritation |
Prevention Tips for Milk Coming Out of Baby’s Nose
The good news is that you can minimize the chances of nasal regurgitation with a few simple adjustments to your feeding routine.
1. Feed in an Upright Position
Keeping your baby at a 45-degree angle (or more) while feeding helps gravity keep the milk in the stomach.
2. Burp Frequently
Burping every 5-10 minutes during feeding (and again after) helps release any trapped air that could push milk up.
3. Monitor Milk Flow
If breastfeeding, express a little milk before latching to slow down letdown. For bottle-feeding, try a nipple with a slower flow.
4. Don’t Overfeed
Stick to your baby’s cues. Feeding smaller amounts more frequently may help reduce regurgitation.
5. Hold Baby Upright After Feeding
Keep your baby upright for at least 20–30 minutes after a feed to allow milk to settle in the stomach.
6. Calm Feeding Environment
A quiet, distraction-free zone helps your baby focus on eating and swallowing effectively.
Tips to Prevent Milk Coming Out of Baby’s Nose
| Action | Why It Helps |
|---|---|
| Feed in upright position | Reduces reflux; uses gravity to help milk stay down |
| Burp during and after feed | Releases gas that can push milk upward |
| Use slower nipple flow | Prevents overfeeding and choking |
| Calm environment | Helps baby concentrate and swallow properly |
| Avoid feeding lying down | Prevents milk from backing into nasal passages |
Connection to Baby Acne and Breast Milk
Did you know that breast milk is often used as a remedy for baby acne? That’s right—many moms dab a little breast milk on their baby’s face to soothe skin irritations. But what if some of that milk ends up in or near the baby’s nose?

It’s safe to say that breast milk is a powerful liquid—not only feeding your baby but also potentially playing a role in minor skin conditions. While milk on the skin is different from milk coming out of the nose, it highlights how interconnected all aspects of newborn care can be.
Connection to Baby Spitting Up Curdled Milk
If you’ve noticed your baby spitting up thick, white clumps that resemble cottage cheese, you’re likely seeing curdled milk. This is digested milk that has spent a little more time in the stomach. While different from nasal regurgitation, both are signs of the digestive system learning and adjusting.

Understanding both phenomena helps you see the bigger picture of your baby’s digestion and development.
What About Sleep?
Many parents are concerned about milk coming out of baby’s nose while the baby is asleep. It can be disconcerting, especially if the baby starts coughing or seems to wake up uncomfortable.
To reduce the risk:
- Avoid feeding right before bedtime without time to burp
- Keep your baby upright for 20 minutes post-feed
- Ensure your baby sleeps on their back on a firm, flat surface
Can It Lead to Choking?
Choking is rare but can happen if the milk gets into the baby’s airway. That’s why positioning and pacing during feeds are so important.
If your baby does choke:
- Stay calm—babies often recover quickly.
- Turn the baby on their side to help drainage.
- Call your pediatrician if choking becomes frequent or is accompanied by breathing difficulty.
How Long Will It Last?
In most cases, nasal regurgitation peaks during the newborn stage and improves significantly by 6 months as your baby’s digestive system matures. If the issue continues past this point or worsens, a pediatric evaluation may be warranted.
Final Thoughts: Milk Coming Out of Baby’s Nose Isn’t Always a Problem
To wrap things up, let’s reinforce a few key points. Milk coming out of baby’s nose is usually a benign and temporary issue related to feeding posture, overfeeding, or immature digestion. It looks alarming, but in most cases, your baby isn’t in danger.
Always keep an eye on patterns: is it happening frequently? Is your baby uncomfortable or losing weight? Trust your instincts and when in doubt, consult your pediatrician.
By understanding how to manage and prevent it, you’ll feel more confident and prepared to navigate your baby’s early feeding journey.
