Getting a stubborn burp out of a baby usually comes down to three things: the right position, gentle but consistent pressure on the belly or back, and patience. Most babies release trapped air within a minute or two when held upright with light back-patting, though some need a position change or a brief pause before the air finally moves. The mechanics are simple, but the details matter, and the evidence on what actually helps might surprise you.
The Three Standard Burping Positions
Pediatric guidance generally describes three positions for burping a newborn, and each one works by the same basic principle: keeping the baby upright so that the air bubble in the stomach rises above the liquid, then applying gentle pressure to the abdomen or back to help it escape. The positions differ mainly in how you support the baby and where the pressure lands.
- Over the shoulder: Hold the baby upright against your chest with the chin resting on or just above your shoulder. One hand supports the baby’s bottom while the other pats or rubs the back. You can do this while standing, sitting, or walking around, which makes it the most versatile option.
- Face-down across the lap: Lay the baby stomach-down across your thighs, with the head slightly higher than the chest. One hand supports the chin and jaw while the other pats the back. The baby’s own weight provides light abdominal pressure, which can help nudge the air bubble out. The catch is that you need to be seated.
- Sitting upright on your lap: Sit the baby on your lap facing away from you, leaning slightly forward. Use one hand to support the chest and gently stabilize the chin, and pat or rub the back with the other hand. This position balances an upright posture with a mild forward tilt that puts some pressure on the stomach.
A 2025 review of burping practices in newborns described all three positions as widely recommended, though the authors noted there is no head-to-head clinical trial showing that any one of these positions is faster or more effective than the others.1PubMed Central. Science of the burp: understanding aerophagia and eructation in newborns That means you are free to use whichever position your baby seems to respond to best, or to rotate through all three during a single burping session.
Practical Tips to Speed Things Up
Position alone sometimes is not enough. A few small adjustments can make the difference between a quick burp and five minutes of fruitless patting.
First, try switching positions if nothing happens after about a minute. Moving the baby from your shoulder to your lap, or from sitting upright to face-down, shifts the air bubble inside the stomach. That change in angle is often all it takes for the bubble to reach the top and release. Some parents find that gently bouncing or swaying while patting also helps the air move.
Second, pay attention to the firmness of your pats. Many new parents are too gentle. You want firm, rhythmic pats on the middle of the back, not hard slaps but not feather-light touches either. Think of it like clapping to a slow beat. A cupped hand creates a slight vibration that can dislodge air more effectively than a flat palm.
Third, timing matters. Most babies swallow the most air in the first few minutes of a feeding, especially from a bottle. Burping mid-feed rather than waiting until the end can be more productive. For bottle-fed babies, pausing every two to three ounces gives you a natural break. For breastfed babies, switching breasts is a good moment to try a burp. The air bubble is smaller at that point and comes up more easily.
Finally, give it a reasonable time limit. If a minute or two in each position produces nothing, the baby may simply not have a trapped bubble. Not every feeding produces significant air swallowing, and forcing the issue can make a content baby fussy for no reason.
Why Some Babies Need More Burping Than Others
Babies swallow air during feeding because they have to coordinate sucking, swallowing, and breathing in rapid sequence. Research on bottle-feeding has shown that each swallow involves roughly half a second of airway closure, and when swallowing speeds up, breathing effectively pauses.2American Physiological Society (J Appl Physiol). Coordination of breathing, sucking, and swallowing during bottle feedings in human infants In between those rapid-fire swallows, small pockets of air get pulled in along with the milk. The faster and more vigorously a baby feeds, the more air tends to come along for the ride.
Breastfed babies generally swallow less air than bottle-fed babies because the breast conforms to the mouth and creates a tighter seal. But latch problems, a fast letdown, or a very hungry baby gulping at the breast can still introduce plenty of air. Crying before or during a feed is another big contributor. A baby who has been wailing for a few minutes will have a belly full of swallowed air before the first sip of milk even arrives.
Premature babies and those with certain feeding difficulties tend to have more trouble coordinating the suck-swallow-breathe pattern, which can mean more air intake and more stubborn burps. If your baby consistently seems uncomfortable and difficult to burp, it is worth mentioning to your pediatrician, though for most healthy babies, the issue resolves on its own as their coordination matures over the first few months.
Does Burping Actually Prevent Colic or Gas Pain?
Here is where the evidence gets uncomfortable for something so universally recommended. The only randomized controlled trial ever conducted on routine burping studied 71 mother-infant pairs over three months and found no significant reduction in colic episodes among the babies who were burped compared with those who were not. More surprisingly, the burped babies actually spit up significantly more, roughly double the rate of regurgitation compared with the non-burping group.3PubMed. A randomized controlled trial of burping for the prevention of colic and regurgitation in healthy infants
That single trial has obvious limitations. Seventy-one pairs is a small sample, and the study cannot account for every variable. But it is the only controlled experiment we have, and the broader review literature has confirmed that robust comparative studies on burping remain absent.1PubMed Central. Science of the burp: understanding aerophagia and eructation in newborns The practice of burping after every feeding persists because of generations of parenting tradition, not because clinical evidence has validated it.
None of this means you should stop burping your baby. If your baby seems uncomfortable with trapped air and clearly feels better after a burp, your own observations are valid evidence for your own child. But if a burp does not come after reasonable effort, you do not need to stress about it. The fear that an unburped baby will suffer from terrible gas pain is not well supported by research. Some babies simply do not need to burp after every feed, and that is fine.
Reducing Air Intake at the Source
Rather than fighting to get air out after the fact, you can reduce how much air gets in during a feeding. For bottle-fed babies, two strategies have some evidence behind them: bottle design and feeding pace.
A large randomized trial of over a thousand infants compared bottom-vented bottles, which use a valve at the base to introduce air without it passing through the milk, with conventional teat-vented bottles, where air enters through holes near the nipple and can create bubbles in the milk. Overall, the bottom-vented bottles did not produce a statistically significant difference in gastrointestinal discomfort at two weeks. But the bottom-vented group did show a lower rate of crying during or after feeding, and in a subgroup of slightly older babies (two to three months old), gastrointestinal discomfort was roughly cut in half with the bottom-vented design.4JAMA Network Open. Feeding Bottles With Different Venting Methods and Gastrointestinal Discomfort in Infants: A Randomized Clinical Trial The effect was modest for very young newborns but became more meaningful as babies got a bit older.
Paced bottle-feeding is the other lever you can pull. The technique involves holding the bottle more horizontally (rather than tilted steeply downward), pausing periodically, and letting the baby control the flow rate rather than gravity doing the work. A study on paced feeding found that it resulted in slower feeding rates and longer feeding times without reducing the amount of milk consumed.5PubMed. Does paced bottle-feeding improve the quality and outcome of bottle-feeding interactions? Slower feeding means less frantic gulping, which should translate to less air swallowed, though the study did not directly measure gas outcomes.
For breastfed babies, the most effective way to reduce air intake is to ensure a deep latch. When the baby takes a large mouthful of breast tissue rather than just clamping on the nipple, the seal is tighter and less air sneaks in. If you hear a lot of clicking or smacking sounds during breastfeeding, the latch may be shallow, and a lactation consultant can help troubleshoot.
Gas Drops and Probiotics
When burping alone is not enough, many parents reach for simethicone drops (sold under brand names you will find in any pharmacy’s baby aisle). Simethicone works by breaking large gas bubbles into smaller ones, theoretically making them easier to pass. The problem is that a well-designed multicenter trial found simethicone was no more effective than a placebo in treating infant colic.6PubMed. Simethicone in the treatment of infant colic: a randomized, placebo-controlled, multicenter trial Both the simethicone group and the placebo group showed perceived improvements, suggesting that the passage of time and parental expectations explain most of the benefit people attribute to gas drops. That said, simethicone is considered safe, so using it is unlikely to cause harm even if the effect is mostly placebo.
Probiotics are a different story. A meta-analysis of randomized controlled trials found that one particular strain, Lactobacillus reuteri DSM 17938, reduced crying time by roughly 40 to 45 minutes per day within two to three weeks.7PLOS ONE. The Efficacy and Safety of the Probiotic Bacterium Lactobacillus reuteri DSM 17938 for Infantile Colic: A Meta-Analysis of Randomized Controlled Trials That is a meaningful reduction for families dealing with hours of daily crying. The caveat is that most of the evidence comes from breastfed babies, and results in formula-fed infants are less consistent. If you are considering probiotics, look for products containing that specific strain and discuss it with your pediatrician.
Normal Spit-Up Versus Something to Worry About
Babies spit up. It is one of the most reliably messy aspects of the first year. Uncomplicated regurgitation in an otherwise healthy baby is not a disease. It happens because of overfeeding, swallowed air, crying, and the simple fact that the valve between the stomach and esophagus is still immature.8PubMed Central. Regurgitation in healthy and non healthy infants If the baby is gaining weight normally, feeding well, and generally content between spitting episodes, the spit-up is cosmetic, not medical.
Gastroesophageal reflux disease (GERD) is different. The warning signs include poor weight gain, refusing to feed, arching of the back during or after feedings, persistent irritability that goes beyond normal fussiness, and respiratory symptoms like chronic coughing or wheezing. If you are seeing those patterns, your pediatrician may want to investigate further. But the typical “happy spitter” who deposits milk on every shirt you own and then grins at you is not a candidate for medical intervention.
One counterintuitive finding: the amount of spit-up may actually increase with burping. As the trial mentioned earlier found, burped babies had about double the regurgitation episodes compared with unburped babies.3PubMed. A randomized controlled trial of burping for the prevention of colic and regurgitation in healthy infants The likely explanation is that the pressure and movement involved in burping can push stomach contents up along with the air. If your baby spits up excessively after burping sessions, experimenting with gentler patting or shorter burping attempts is worth trying.
Positioning After Feeds
Conventional advice says to hold a baby upright for 15 to 30 minutes after a feeding to reduce reflux. The reality is more nuanced than “upright is always better.” A study of infants with chronic respiratory symptoms found that while reflux episodes were actually more frequent in the upright position than when lying down, the reflux-related respiratory symptoms were significantly fewer when upright. After adjusting for the total number of reflux events, respiratory symptoms dropped from about 11 percent of reflux episodes when lying down to about 4 percent when upright.9PubMed Central. The Efficacy of the Upright Position on Gastro-Esophageal Reflux and Reflux-Related Respiratory Symptoms in Infants With Chronic Respiratory Symptoms
In other words, upright positioning does not prevent reflux from happening, but it does seem to make each reflux event less likely to cause breathing-related problems. For the average healthy baby who just spits up, the practical takeaway is that holding them upright for a few minutes after feeding is reasonable but not an ironclad requirement.
One position to avoid: the semi-reclined infant seat. An older but frequently cited study in the New England Journal of Medicine found that placing babies in an infant seat after feeding actually worsened reflux compared with placing them on their stomachs, because the semi-upright slouch compresses the abdomen and pushes stomach contents upward.10PubMed. The infant seat as treatment for gastroesophageal reflux Fully upright against your body is fine. Slumped in a bouncer right after a full feeding is not ideal. (And prone positioning is only mentioned here in the context of that study’s findings, not as a sleep recommendation. Safe sleep guidelines call for back sleeping on a flat surface.)
For babies with frequent regurgitation, a trial comparing cereal-thickened formula to upright positioning found that the thickened formula was significantly more effective at reducing spit-up frequency over eight weeks.11PubMed. Effect of cereal-thickened formula and upright positioning on regurgitation, gastric emptying, and weight gain in infants with regurgitation Thickening feeds is a conversation to have with your pediatrician rather than something to try on your own, but it is one more data point showing that positioning alone has limits.
When Breastfeeding Mothers Change Their Diet
If you are breastfeeding and your baby seems especially gassy or colicky, maternal diet is worth considering. A randomized controlled trial had breastfeeding mothers of colicky infants eliminate common allergens including cow’s milk, eggs, peanuts, tree nuts, wheat, soy, and fish. After about a week, roughly three-quarters of the babies in the elimination diet group showed reduced distress, compared with just over a third in the control group.12Pediatrics. Effect of a Low-Allergen Maternal Diet on Colic Among Breastfed Infants: A Randomized, Controlled Trial
A mixed-methods study exploring what mothers actually eliminate found that dairy products and cruciferous vegetables (cabbage, broccoli, cauliflower) together accounted for about half of all food eliminations, and many mothers reported noticeable improvements within a few days of cutting dairy.13Heliyon. Maternal dietary change and infant colic: A mixed-method study exploring extent, impact and influencing factors Whether those improvements reflect a genuine food sensitivity or a coincidence with the natural waning of colic is hard to say in individual cases. But if your baby’s fussiness is severe and persistent, a two-week trial of eliminating dairy is a low-risk experiment that your pediatrician can help you evaluate. Cutting multiple food groups at once without guidance is not recommended, since it can affect your own nutrition.
The relationship between maternal diet and infant gas is not fully understood. Cow’s milk protein allergy is a real condition that affects a small percentage of infants, and it can cause gastrointestinal symptoms that look a lot like ordinary gas or colic. If eliminating dairy from your diet leads to a dramatic improvement, that is a signal to discuss with your doctor, because the baby may need evaluation for a milk protein sensitivity that would also affect formula choices down the road.
