Babies get hiccups after burping because the release of a large air bubble can briefly irritate or stimulate the diaphragm, the thin muscle beneath the lungs that controls breathing. When air moves suddenly through the upper digestive tract during a burp, it can trigger a reflexive spasm in this muscle, producing that familiar “hic” sound. This is extremely common in newborns and almost always harmless.
The connection between burping and hiccups comes down to how underdeveloped a baby’s digestive and nervous systems are in the first months of life. Understanding what’s happening inside your baby’s body can help you reduce how often it happens and feel confident that everything is working normally.
Why Burping Triggers Hiccups
A hiccup is an involuntary contraction of the diaphragm followed by a quick closing of the vocal cords. In adults, this rarely happens because the nerve pathways controlling the diaphragm are mature and less reactive. In babies, those same pathways are still developing, which makes the diaphragm more sensitive to stimulation.
When your baby burps, a pocket of trapped air travels up through the esophagus and past the diaphragm. That sudden movement can stimulate the nerve that runs from the brain down to the diaphragm, causing it to contract involuntarily. Think of it like a reflex: the nerve gets nudged, and the diaphragm twitches in response. The younger your baby is, the more easily this reflex fires, which is why hiccups are far more frequent in newborns than in older children.
How Air Gets Trapped in the First Place
The reason your baby needs to burp at all is that babies swallow air during feeding. This is called aerophagia, and some feeding situations make it worse. A baby who is gulping, spluttering, or struggling to manage milk flow will take in more air than one feeding calmly. A poor latch during breastfeeding, difficulty managing a fast bottle flow, or oral restrictions like tongue tie can all increase the amount of air swallowed.
A newborn’s stomach is tiny. In the first days of life it holds roughly a teaspoon of liquid, growing to about the size of an egg by one month. When a small stomach fills with both milk and air, the pressure builds quickly. That pressurized air has to go somewhere, and when it finally escapes during a burp, the sudden release is more likely to set off the diaphragm.
Reducing Air Intake During Feeds
You can’t eliminate air swallowing entirely, but a few adjustments make a noticeable difference. If you’re bottle feeding, tilt the bottle at roughly a 45-degree angle so that milk fills the nipple completely. When the nipple is only partially filled, your baby sucks in air along with each swallow. Choose a slow-flow nipple appropriate for your baby’s age so they aren’t gulping to keep up with a fast stream of milk.
For breastfeeding, focus on getting a deep latch where your baby’s mouth covers a wide portion of the areola, not just the tip of the nipple. A shallow latch creates gaps where air slips in. If your letdown is fast and your baby is choking or sputtering, try leaning back slightly so gravity slows the flow.
Paced feeding also helps. Instead of letting your baby drain a bottle in one go, pause every ounce or two and give them a moment to swallow and breathe. Smaller, more frequent burps during the feeding release air gradually rather than letting it build into one large bubble that jolts the diaphragm all at once.
Better Burping Techniques
How you burp your baby can influence whether hiccups follow. The goal is a gentle, steady release of air rather than a forceful eruption. Two positions work well. The first is over the shoulder: hold your baby upright with their head resting just above your shoulder, supporting their head with your hand or shoulder, and gently pat or rub their back. The upright position lets gravity help the air rise naturally.
The second is sitting upright on your lap. Support your baby’s chest and head with one hand while patting their back with the other. In both positions, keep the motion gentle. Hard, rapid pats don’t get the air out faster, but they can startle your baby and contribute to more diaphragm irritation. If no burp comes after a couple of minutes, it’s fine to stop and try again later. Not every feeding produces a trapped air bubble that needs to come out.
How Long Hiccups Last
Most hiccup episodes in babies resolve on their own within 5 to 10 minutes. If your baby gets hiccups after a burp and they don’t stop within that window, the American Academy of Pediatrics suggests trying to resume feeding for a few minutes. The swallowing motion can help relax the diaphragm and interrupt the spasm cycle. Beyond that, there’s not much you need to do. Hiccups bother parents far more than they bother babies. Most infants continue to coo, look around, or even fall asleep right through them.
Hiccup frequency varies, but several episodes a day is normal for newborns. Babies actually hiccup in the womb starting in the first trimester, so by the time they’re born, hiccups are already a well-practiced reflex. The frequency tends to decrease significantly after about 6 months as the digestive and nervous systems mature.
What Not to Try
Some home remedies that work for adults are unsafe for babies. Gripe water and sugar water are commonly suggested, but there is limited evidence that either stops hiccups, and infants under six months should not be given anything other than breast milk or formula. Extra liquids can interfere with calorie intake and, in some cases, introduce contaminants. Startling a baby, holding their breath, or pressing on their fontanelle are all folk remedies that range from useless to dangerous. Since hiccups pose no risk to your baby, the safest approach is simply to wait them out or offer a brief feeding.
When Hiccups Signal Something Else
Occasional hiccups after burping are a normal part of infancy. But if your baby hiccups constantly throughout the day, seems distressed or in pain during episodes, arches their back while feeding, spits up large amounts frequently, or is not gaining weight as expected, these patterns together may point to gastroesophageal reflux that goes beyond typical spit-up. In reflux, stomach acid travels back up into the esophagus and irritates the diaphragm from below, triggering persistent hiccups along with discomfort.
The hiccups themselves are not the concern in this scenario. It’s the combination of hiccups with feeding difficulties, poor weight gain, or visible distress that warrants a conversation with your pediatrician. Isolated hiccups after a good burp, even if they happen several times a day, are just your baby’s immature nervous system doing exactly what it’s supposed to do.
