Baby Choking or Coughing on Milk or Liquids
The short answer
It is common for babies to occasionally cough, sputter, or have milk come out of their nose during feeding, especially in the early weeks. This usually happens because of a fast milk flow (letdown), an immature swallowing coordination, or feeding in a position that is too reclined. Occasional choking episodes during feeding that resolve quickly are usually not serious. Adjusting feeding position, pacing the feed, and using a slower-flow nipple can help.
By Age
What to expect by age
Newborns are still learning to coordinate sucking, swallowing, and breathing. Occasional choking or sputtering is very common, especially during a strong letdown for breastfed babies or with a fast-flow bottle nipple. Milk coming out of the nose happens because the back of the nose and throat are connected. Hold your baby more upright during feeding, take breaks, and use a slow-flow nipple for bottles.
Feeding coordination improves significantly by this age. If your baby is still frequently choking or coughing during feeds, it may indicate a structural issue like laryngomalacia (floppy airway) or dysphagia (swallowing difficulty). Persistent choking, wet or gurgly breathing after feeds, or frequent pneumonia should be evaluated.
As babies start drinking from cups, occasional choking on liquids is normal as they learn a new drinking method. Open cup practice with small sips can help develop the skill. If your baby has always had difficulty with liquids and continues to choke frequently, a swallowing evaluation (video fluoroscopic swallow study) may be recommended.
What Should You Do?
When to take action
- Occasional sputtering during a fast letdown or at the start of a feeding
- Milk coming out of the nose once in a while during feeding
- Brief coughing that resolves on its own within seconds
- Mild choking when learning to drink from a new type of cup
- Choking or coughing happens at most feeds rather than occasionally
- Your baby seems to have a wet, gurgly voice or breathing after feeds
- Your baby is not gaining weight well and also has feeding difficulty
- Milk frequently comes out of the nose with every feed
- Your baby turns blue, goes limp, or stops breathing during a feeding
- Your baby has recurrent pneumonia or respiratory infections (could indicate aspiration)
- Your baby chokes and cannot recover - is coughing for more than a minute or having breathing difficulty
- Your baby has been diagnosed with a swallowing problem and symptoms are worsening

I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
My Baby Coughs While Feeding
Occasional coughing during feeding is very common, especially in newborns who are still learning to coordinate sucking, swallowing, and breathing. It often happens with a fast milk flow or letdown. However, if your baby coughs with every feed or turns blue or has difficulty breathing, this needs medical evaluation to rule out swallowing difficulties.
My Baby Gulps Air While Feeding
Swallowing some air during feeding is normal for all babies, but excessive air gulping can lead to gas, hiccups, and spit-up. Common causes include fast milk flow, poor latch (if breastfeeding), bottle nipple flow that's too fast or slow, and crying before feeds. Simple adjustments to feeding position, pacing, and equipment can usually help reduce air intake significantly.
Paced Bottle Feeding Concerns
Paced bottle feeding is a technique that slows down the flow of milk to more closely match the natural pace of breastfeeding. It helps prevent overfeeding, reduces gas and spit-up, and supports babies who are both breast and bottle fed. If your baby seems to gulp, choke, or finish bottles extremely quickly, paced feeding can help. It involves holding the baby more upright, keeping the bottle horizontal, and pausing every few minutes.
When to Introduce Allergens to Baby
Current guidelines recommend introducing common allergens (peanut, egg, cow's milk products, tree nuts, wheat, soy, fish, shellfish, sesame) starting around 4-6 months when your baby is developmentally ready for solids. The landmark LEAP study showed that early introduction of peanuts (by 4-6 months) reduced peanut allergy risk by 80% in high-risk infants. Do not delay allergens - the old advice to wait until 1-3 years has been reversed because early exposure actually prevents allergies.
Baby Biting Nipple While Nursing
Biting during breastfeeding is a common challenge, especially when babies start teething. It can be startling and painful, but it is almost always a phase that can be managed. Babies cannot actively nurse and bite at the same time because their tongue covers the lower teeth during proper sucking. Biting typically happens at the beginning or end of a feed when the latch is not active. With some gentle strategies, most babies learn quickly that biting ends the feeding session.
