Quick Answer
Babies need to burp because they swallow air during feeding, and that trapped air can cause discomfort, fussiness, and spitting up if it is not released. Burping helps move swallowed air up and out of the stomach before it travels further into the digestive system and causes gas pain.
How Air Gets Trapped During Feeding
Whether breastfed or bottle-fed, babies swallow some air with every feed. This happens because:
- The latch or seal is not always perfect: Any gap between your baby's mouth and the breast or bottle nipple allows air to enter alongside the milk
- Fast milk flow: If milk comes quickly — from a fast letdown or a fast-flow bottle nipple — babies tend to gulp, swallowing more air in the process
- Crying before a feed: A baby who cries before feeding will swallow extra air, which then gets trapped in the stomach during the feed
- Immature digestive system: Newborns have not yet developed the muscle coordination to move air through their digestive system efficiently, making burping an important assist
What Happens If a Baby Does Not Burp
If swallowed air is not released, it can:
- Cause discomfort and fussiness during or after feeds
- Lead to spitting up as the air forces milk back up
- Travel further into the digestive system and cause gas pain and bloating
- Make your baby feel full before they have had enough milk, leading to a shorter feed and hunger again soon after
Do All Babies Need to Burp?
Not always. Some babies — particularly breastfed babies with a good latch — swallow very little air and may not need to burp after every feed. If your baby seems comfortable and settled after a feed without burping, there is no need to force it. Follow your baby's cues rather than a rigid rule.
How to Burp Your Baby
There are three main burping positions — try each to find what works best for your baby:
- Over the shoulder: Hold your baby upright against your chest with their chin resting on your shoulder. Support their bottom with one hand and gently pat or rub their back with the other
- Sitting upright on your lap: Sit your baby on your lap facing away from you. Support their chest and chin with one hand (keeping their head upright) and gently pat or rub their back with the other
- Face-down across your lap: Lay your baby face-down across your lap, supporting their head so it is slightly higher than their chest. Gently pat or rub their back
When to Burp During a Feed
- Breastfeeding: Burp when switching sides and at the end of the feed
- Bottle feeding: Burp every 60 to 90 ml (2 to 3 oz) during the feed and again at the end
- If your baby is fussy mid-feed: Pause and try burping — trapped air can make a baby pull off and fuss even when they are still hungry
When It's Worth Checking In With Your Pediatrician
Speak to your pediatrician if:
- Your baby seems consistently uncomfortable after feeds despite regular burping
- Your baby is spitting up large amounts or projectile vomiting
- Your baby is not gaining weight adequately
- You suspect reflux or a digestive issue may be contributing to their discomfort
Key Takeaway
Burping is an important part of feeding because it releases the air babies inevitably swallow during a feed. Without it, trapped air can cause discomfort, fussiness, and spitting up. That said, not every baby needs to burp after every feed — if your baby is settled and comfortable, trust that and move on.
