Most childhood gas resolves with a combination of simple physical techniques and minor dietary adjustments, not medication. Gentle belly massage, proper feeding positions, and identifying the specific foods behind the bloating tend to do more than any drops or supplements. Because the causes of gas differ quite a bit between infants and older children, the remedies that help depend heavily on the age of the child and what is actually producing the gas in the first place.
Why Kids Get So Gassy
Gas in the digestive tract comes from two main sources: swallowed air and the fermentation of undigested carbohydrates by gut bacteria. Babies are especially prone to both. During bottle feeding, infants adjust their sucking and swallowing patterns based on the flow of milk, and higher flow rates can lead to larger, faster swallows that trap more air in the stomach.1PubMed Central. Ventilatory sparing strategies and swallowing pattern during bottle feeding in human infants Breastfed babies swallow air too, particularly if the latch is shallow or the let-down is fast.
The other half of the equation is the gut microbiome. In the first weeks of life, an infant’s intestinal bacteria are still colonizing the gut. Research on preterm infants found that measurable hydrogen and carbon dioxide gas from bacterial fermentation begins appearing around two weeks of age and increases steadily over the first month as the microbial community grows.2PubMed Central. Evolution of Intestinal Gases and Fecal Short-Chain Fatty Acids Produced in vitro by Preterm Infant Gut Microbiota During the First 4 Weeks of Life This is a normal developmental process, but it means young babies produce gas from food fermentation before their gut has fully learned how to move that gas along efficiently. In older children, gas is more often tied to specific dietary triggers or swallowing habits.
Physical Techniques That Actually Help
For infants, the most reliable immediate relief comes from physical maneuvers you can do at home without buying anything. Laying your baby on their back and gently cycling their legs in a pedaling motion compresses the abdomen and helps trapped gas move through the intestines. Gentle clockwise massage on the belly, following the path of the large intestine, works on the same principle. A small trial found that pediatric massage reduced crying time and improved sleep duration in colicky infants, though it was tested alongside other interventions rather than in isolation.3Europe PMC. Clinical efficacy of magnetotherapy combined with pediatric massage on infantile colic
Tummy time while your baby is awake and supervised puts gentle pressure on the stomach and can encourage gas to pass. For older toddlers and children, having them lie on their left side for a few minutes or pull their knees up to their chest in a gentle hug position mimics what the bicycle-legs trick does for babies.
Feeding position matters more than most parents realize. Keeping an infant’s head elevated during and after feeding reduces the amount of air that gets trapped. A study of over 160 infants found that those fed with their head in an upright position had significantly less respiratory and ear illness compared to infants fed without specific positioning instructions, likely because upright feeding reduces both air swallowing and reflux.4Nature / Scientific Reports. Feeding young infants with their head in upright position reduces respiratory and ear morbidity While that study focused on respiratory outcomes, the upright position also allows swallowed air to rise to the top of the stomach where it can be burped out more easily, rather than getting pushed deeper into the intestines.
Burping your baby at natural pauses during feeding, not just at the end, gives trapped air more chances to escape before it moves into the lower digestive tract. For bottle-fed babies, using a slow-flow nipple can reduce how much air gets gulped with each swallow.
Fruit Juice and Other Dietary Triggers
For children old enough to eat solid food or drink juice, what they consume is often the biggest driver of gas. Fruit juices are a surprisingly common culprit, and not all juices are equal. Apple juice contains a high ratio of fructose to glucose, and research has shown that fructose, not sorbitol as previously suspected, is the sugar responsible for the spike in intestinal gas after apple juice consumption in toddlers.5PubMed. Apple juice malabsorption: fructose or sorbitol? When fructose is not fully absorbed in the small intestine, it travels to the colon where bacteria ferment it, producing hydrogen gas, bloating, and sometimes diarrhea.
Pear juice is another offender. In a study comparing pear juice and white grape juice in infants, most of the babies given pear juice showed signs of carbohydrate malabsorption, along with increased physical restlessness and higher metabolic rate, while white grape juice caused far fewer problems.6PubMed. Consequences of incomplete carbohydrate absorption from fruit juice consumption in infants The connection between juice and infant discomfort goes further: a study specifically examining colicky infants found that those with colic showed carbohydrate malabsorption when fed apple juice, while non-colicky infants absorbed the same juice without trouble. The link was strongest with juices high in sorbitol and with a high fructose-to-glucose ratio.7PubMed. Association between infantile colic and carbohydrate malabsorption from fruit juices in infancy
If your child is gassy and drinks fruit juice regularly, cutting back on apple and pear juice is one of the simplest changes you can make. White grape juice tends to be better tolerated. For older kids, the usual suspects apply as well: beans, cruciferous vegetables like broccoli and cauliflower, and carbonated drinks all increase intestinal gas production. Carbonated beverages are worth singling out because eliminating them can reduce the sheer volume of gas in the gut, independent of any fermentation.8Karger Publishers.

When Dairy Is the Problem
Lactose intolerance deserves its own mention because it is frequently missed in young children, and the symptoms overlap heavily with ordinary gassiness. Children who lack enough lactase enzyme to break down the lactose in milk end up fermenting that sugar in their colon, producing gas, bloating, and loose stools. Secondary lactose intolerance, which develops temporarily after a bout of gastroenteritis or prolonged diarrhea, is more common in young children than the genetic, permanent form. One study of children aged one to five with chronic diarrhea found that about a third were diagnosed with secondary lactose intolerance, with abdominal distention being one of the most common symptoms.9Indus Journal of Bioscience Research. Incidence of Secondary Lactose Intolerance in Chronic Diarrhea in Children Age 1-5 Years
If your child has recently recovered from a stomach bug and is suddenly gassier or more bloated than usual, temporarily reducing dairy can help. The gut lining typically heals within a few weeks, and most children can resume dairy without issues.10Pakistan BioMedical Journal. Clinical Assessment and Demographic Insights of Lactose Intolerance Among Diarrheal Children at Hyderabad, Pakistan For breastfed infants, cow’s milk protein sensitivity is a separate issue from lactose intolerance. Some babies react to cow’s milk protein that passes through breast milk, and in rare cases this sensitivity can be present from birth due to fetal sensitization.11PubMed Central. Fetal sensitization to cow’s milk protein and wheat If your infant has persistent gas, mucousy stools, or skin reactions alongside the fussiness, a pediatrician can help determine whether a trial elimination of dairy from your diet or a formula switch is warranted.
What About Maternal Diet for Breastfed Babies?
Breastfeeding mothers frequently hear that eating broccoli, garlic, onions, or spicy food will make their baby gassy. This belief is deeply held and widely shared, but the evidence behind it is thin. A qualitative study of breastfeeding women found that mothers strongly believed their diet influenced their infant’s cry-fuss behavior, even though the scientific evidence available at the time did not support the connection.12PubMed Central. “Something is wrong with your milk”: Qualitative study of maternal dietary restriction and beliefs about infant colic
The one exception with real evidence is cow’s milk protein. When a breastfeeding mother consumes dairy, intact proteins can pass into breast milk and trigger a reaction in sensitive infants. That mechanism is well documented. But the idea that eating a gas-producing vegetable will make your breast milk gassy is not how breast milk works. The gas you produce in your own gut from eating cabbage does not transfer into milk. If you are a breastfeeding parent restricting your diet heavily out of fear it is causing your baby’s gas, it is worth discussing with your pediatrician before cutting out entire food groups unnecessarily.
Simethicone Drops and Over-the-Counter Options
Simethicone drops, sold under brand names like Mylicon and Gas-X Infant, are the most commonly purchased remedy for baby gas. Simethicone works by breaking up gas bubbles in the stomach and intestines, making them easier to pass. It is considered safe and is not absorbed into the bloodstream. The problem is not safety but effectiveness. A randomized, placebo-controlled multicenter trial found that simethicone was no more effective than placebo in treating infant colic. Even when researchers specifically looked at infants whose parents described their symptoms as gas-related, simethicone still performed no better than the dummy drops.13PubMed. Simethicone in the treatment of infant colic: a randomized, placebo-controlled, multicenter trial
Both the simethicone group and the placebo group improved over the study period, which is a common finding in colic research. Colic tends to resolve on its own as the infant matures, making it easy for any treatment given during that window to get credit for a natural improvement. That said, simethicone is cheap, safe, and some parents swear by it. If you feel it helps your child, there is no medical reason to stop using it, but the evidence suggests the improvement is likely a combination of the placebo effect and the passage of time rather than the medication itself.
Probiotics for Infant Gas
Probiotics have stronger evidence than simethicone, at least for prevention. A meta-analysis of five randomized trials involving over 600 infants found that probiotics given preventively reduced daily crying time by roughly 55 minutes compared to controls at the three-week mark, with no increase in adverse events.14Europe PMC. Probiotics to prevent infantile colic The strain studied most often in this context is Lactobacillus reuteri, and the effect appears strongest in breastfed infants.
For older children with recurrent gas, probiotic-rich foods like yogurt or kefir can help maintain a healthy gut bacterial balance that processes food more efficiently. The evidence for probiotics as a treatment for gas already in progress is less clear-cut than for prevention, but given their safety profile, they are a reasonable option to try.
Herbal Remedies and Gripe Water
Gripe water is one of those products every parent has heard of and few can explain. Modern gripe water formulations typically contain some combination of fennel, chamomile, ginger, or lemon balm, though the ingredients vary wildly by brand. Some older formulations contained alcohol or sodium bicarbonate, which are best avoided in infants.
There is some clinical support for certain herbal blends. A randomized, double-blind trial tested a specific combination of chamomile, fennel, and lemon balm extract in breastfed colicky infants and found that colic improved within one week of treatment, with no reported side effects.15PubMed. A randomized double-blind placebo-controlled trial of a standardized extract of Matricariae recutita, Foeniculum vulgare and Melissa officinalis (ColiMil) in the treatment of breastfed colicky infants Fennel in particular has a long traditional history as a carminative, meaning it relaxes smooth muscle in the intestinal wall and allows gas to pass more freely.
The catch with gripe water and herbal products is that they are not regulated as medications, so quality and dosing vary between brands. If you choose to use one, look for a product that lists its active ingredients clearly, does not contain alcohol or sugar, and ideally has been tested in some form. Give it in small amounts and watch for any allergic reaction, especially the first time.
Air Swallowing in Older Children
While most infant gas discussions focus on feeding mechanics, older children sometimes develop a habit called aerophagia, where they repeatedly swallow air without realizing it. This can happen during eating, drinking, gum chewing, talking excitedly, or as a nervous habit. The swallowed air accumulates in the stomach and intestines, causing visible abdominal distention and frequent belching or flatulence.
Functional aerophagia in children is more common than many pediatricians recognize. Reducing carbonated drinks and educating both the child and parents about the swallowing pattern are considered key parts of management. Parents can learn to recognize the gulping sounds and movements that indicate air swallowing, which helps them gently redirect the child’s behavior.8Karger Publishers. Functional Aerophagia in Children: A Frequent, Atypical Disorder For children who eat very quickly, slowing down meals and encouraging smaller bites can make a noticeable difference. Using a straw for drinks, chewing gum, and sucking on hard candy all increase the amount of air that ends up in the gut.
Hands-On Therapies
Some parents explore osteopathic treatment or chiropractic care for persistently gassy babies. A randomized trial of osteopathic manual therapy for infant colic found that treated babies had statistically significant reductions in crying after the first session and at two-week follow-up compared to controls. However, the study found no significant differences between groups specifically for gas or eructation (burping) as measured outcomes, and the overall severity scores only trended toward significance without fully reaching it.16MDPI (Healthcare). Osteopathic Manual Therapy for Infant Colic: A Randomised Clinical Trial The crying reduction is encouraging, but it is not clear whether the mechanism is gas relief specifically or a more general calming effect from the handling and attention.
Given the cost and the modest evidence, hands-on therapies are best considered a later option after the simpler physical techniques, dietary adjustments, and probiotic strategies have been tried.
When Gas Warrants a Doctor Visit
Most gas in children is completely benign, even when it looks and sounds dramatic. A red-faced baby straining to pass gas is usually just a baby whose coordination between abdominal muscles and pelvic floor has not matured yet, not a baby in medical distress. But certain patterns do warrant a call to the pediatrician:
- Bloody stool: even small streaks of blood, especially in an infant, can indicate a milk protein allergy or other conditions that need evaluation.
- Failure to gain weight: if persistent gas and fussiness are accompanied by poor weight gain, the underlying issue could be malabsorption rather than simple gassiness.
- Vomiting: occasional spit-up is normal, but forceful or projectile vomiting alongside gas and distention could signal an obstruction or other structural problem.
- Fever with abdominal distention: gas alone does not cause fever. If both are present, an infection or inflammatory process needs to be ruled out.
- Sudden onset in a previously comfortable child: a child who was not gassy and suddenly develops severe abdominal pain with distention may have something more than dietary gas.
Distinguishing routine functional gas from something that needs medical attention can be tricky, and the broad spectrum of possible causes for abdominal pain in children ranges from completely benign to conditions requiring urgent intervention.17International Journal For Multidisciplinary Research. Abdominal Pain in Children: A Comprehensive Review of Functional and Organic Etiologies, Pathophysiology, Diagnostic Approach, and Management When in doubt, calling your pediatrician is always the right move. They can usually tell you quickly over the phone whether the symptoms need an in-person visit or whether you can safely continue managing things at home.
A Quick-Reference Checklist by Age
Because the best approach depends so much on how old your child is, here is a practical breakdown:
For newborns and young infants under six months, focus on feeding technique first. Keep the head elevated, use a slow-flow nipple for bottles, burp frequently during feeds, and use bicycle legs and tummy massage when gas seems to build up. If the baby is breastfed and persistently uncomfortable, consider a trial elimination of dairy from your own diet for two weeks to see if it helps. Probiotics containing Lactobacillus reuteri have the best evidence for reducing fussiness in this age group.
For babies six to twelve months who are starting solid foods, pay attention to which new foods coincide with increased gassiness. Limit fruit juice, and when you do offer it, white grape juice is generally better tolerated than apple or pear. Introduce high-fiber and gas-producing vegetables gradually, giving the gut time to adjust to each new food.
For toddlers and older children, the most productive changes are dietary. Cut back on carbonated drinks, reduce juice intake, and notice whether specific foods consistently cause problems. If your child eats quickly, encouraging slower meals with smaller bites reduces air swallowing. For a child who seems to swallow air as a habit, gently bringing their attention to it and reducing gum chewing can help over time.
