Quick Answer
If you do not burp a baby who has swallowed air during a feed, the trapped air can cause discomfort, fussiness, spitting up, and difficulty settling after the feed. In most cases the consequences are temporary and not dangerous; the air will eventually pass through the digestive system as wind from below. However, for babies who are prone to reflux or who swallow a lot of air during feeds, skipping burping can make an uncomfortable situation significantly worse. The need to burp varies considerably between babies, and some babies genuinely need very little burping while others need it consistently after every feed.
What Actually Happens When Air Gets Trapped
During feeding, babies inevitably swallow some air alongside milk. This is true of both breast and bottle feeding, though the amount varies depending on latch quality, feeding position, nipple flow rate, and how vigorously the baby feeds. The swallowed air collects in the stomach as a bubble, sitting above the milk.
When this air bubble is not released by burping, one of several things happens:
- Discomfort and fussiness: The air bubble creates pressure in the stomach that can feel uncomfortable, particularly if the stomach is also full of milk. A baby with trapped wind may pull up their knees, arch their back, grimace, or cry after a feed that seemed to go well
- Early satiety: A large air bubble in the stomach takes up space and can make a baby feel full before they have taken enough milk. This can result in a baby who seems satisfied immediately after a feed but becomes hungry again very quickly, as the air moves through and the stomach empties faster than expected
- Spitting up: When the air bubble finally rises and escapes, it often brings milk with it. This is the mechanism behind much of the spitting up that is common in the early months. Burping mid-feed and after a feed reduces the likelihood of milk being carried up with the air
- Wind from below: If the air does not come back up, it travels through the digestive system and exits as flatulence. This is not harmful but can be uncomfortable for the baby in the process
- Difficulty settling: A baby with trapped wind often cannot settle to sleep after a feed and will cry or fuss until the discomfort resolves, which can take considerably longer than a burp would have
Does Every Baby Need to Be Burped?
No. The need to burp varies significantly between babies and between feeds. Some babies, particularly exclusively breastfed babies with a good latch, swallow very little air and may rarely need burping or may burp spontaneously without any assistance. Other babies, particularly those who feed quickly, those with a shallow latch, and bottle-fed babies, consistently swallow more air and benefit from regular burping during and after every feed.
The practical answer is to try burping and be guided by your baby's response. A baby who settles easily after feeds without burping and does not show signs of wind discomfort may not need consistent burping. A baby who is fussy, gassy, or unsettled after feeds almost always benefits from more consistent and thorough winding.
Signs Your Baby Needs to Be Burped More Consistently
- Fussiness or crying shortly after a feed that seemed to go well
- Pulling up the knees or arching the back after feeding
- Frequent spitting up, particularly in larger amounts
- Seeming hungry again very quickly after a full feed
- Audible stomach gurgling and visible discomfort
- Difficulty settling to sleep after feeds
How Long Should You Try to Burp a Baby?
Most burping attempts should take no more than 3 to 5 minutes. If no burp comes after several minutes of gentle patting or rubbing, it is reasonable to conclude that either there is no significant air to release or the air is not accessible from the current position. Try a different burping position, and if still unsuccessful, lay your baby down and see whether they settle. If they do, the burp was not needed. If they remain unsettled, try burping again after a few minutes in a different position.
Effective Burping Positions
- Over the shoulder: Hold your baby upright against your shoulder with their chin resting on it, supporting their bottom with one hand and patting or rubbing their back with the other. This is the most commonly used position and works well for most babies
- Sitting upright on your lap: Sit your baby on your lap facing away from you, supporting their chest and chin with one hand (be careful not to put pressure on the throat) and patting their back with the other. This position is particularly effective for babies who do not burp easily over the shoulder
- Face down across your lap: Lay your baby face down across your lap, with their head slightly higher than their chest, and gently pat or rub their back. The gentle pressure of the lap on the stomach can help move air upward
Varying the position is the most effective strategy when burping is proving difficult. What works best varies between babies and sometimes between feeds for the same baby.
Burping and Reflux
For babies with gastro-oesophageal reflux (GOR or GORD), consistent and thorough burping is particularly important. Trapped air in the stomach increases pressure on the lower oesophageal sphincter, the valve between the stomach and oesophagus, and can worsen reflux symptoms. Burping mid-feed as well as after the feed, and keeping the baby upright for 20 to 30 minutes after feeding, can meaningfully reduce the frequency and severity of reflux episodes.
Reducing the amount of air swallowed during the feed in the first place is also helpful. The Emulait Glass Classic Bottle features a breast-shaped nipple designed to support a deep, comfortable latch that reduces the air swallowed during a feed, which means less trapped wind to deal with afterward.
When to Speak to Your Pediatrician
Speak to your pediatrician if:
- Your baby is consistently very difficult to wind despite trying multiple positions
- Wind discomfort is severe and frequent, suggesting colic or reflux
- Spitting up is very large in volume, forceful (projectile), or contains blood
- Your baby is not gaining weight adequately
- Wind discomfort is significantly disrupting feeding and sleep
Key Takeaway
Not burping a baby who has swallowed air during a feed can lead to discomfort, fussiness, spitting up, early satiety, and difficulty settling. The consequences are rarely dangerous but can make the post-feed period significantly more uncomfortable for your baby. Whether your baby needs burping depends on how much air they swallow: some babies rarely need it, others need consistent burping mid-feed and after every feed. Be guided by your baby's behaviour after feeds, try multiple positions if a burp does not come easily, and speak to your pediatrician if wind discomfort is persistent or severe.
