Most newborn stomach pain comes from gas, reflux, or colic, and the good news is that simple hands-on techniques can bring real relief. Gentle belly massage, proper feeding positions, and bicycle leg movements are the most effective first steps, and they work for the majority of fussy, gassy babies without any products or medications.
Why Newborns Get Stomach Pain
A newborn’s digestive system is brand new and still learning to process milk, move gas through the intestines, and coordinate the muscles needed for digestion. The most common culprits in the first few months are swallowed air (during feeding or crying), gastroesophageal reflux (spitting up), and constipation. Reflux is especially common and usually looks alarming but rarely causes harm. Most babies with reflux spit up right after feeding and may sound hoarse or mucousy, but they continue to gain weight and feed normally.
Then there’s colic, which is the catch-all term for prolonged, unexplained crying. The standard definition is crying more than three hours per day, more than three days per week, for longer than three weeks. Colic typically peaks around six weeks and resolves by three to four months. It’s frustrating precisely because there’s no single fix, but many of the techniques below reduce crying time significantly.
Belly Massage and Bicycle Legs
Physical techniques are the safest, most immediate way to help a gassy or uncomfortable newborn. They work by encouraging trapped air to move through the intestines toward the bowels, where it can be released.
For belly massage, lay your baby on their back on a soft surface. Wait at least 45 minutes after a feeding to reduce the chance of spitting up. Using a small amount of baby oil or lotion, place your fingertips on the lower right side of your baby’s belly (where the large intestine begins) and gently stroke across to the lower left side (where the colon ends). When you’re looking down at your baby, this means moving from your left to your right. Use light, steady pressure. You can also try gentle clockwise circles around the navel. Maintain eye contact and watch for cues: if your baby stiffens their arms or turns away, pause and try again later.
Bicycle legs are equally effective. With your baby on their back, gently move their legs in a cycling motion, alternating one knee toward the chest and then the other. You can also gently twist their hips and legs side to side. These movements physically push gas through the digestive tract and often trigger a bowel movement in constipated babies. Many parents find that combining a few minutes of belly massage with bicycle legs produces results within minutes.
There’s also a pressure point on your baby’s foot, located on the upper middle area just below the pad, that corresponds to the stomach and intestines. Gently stroking this spot may provide additional comfort.
Feeding Adjustments That Reduce Gas
How your baby eats matters as much as what they eat. Swallowed air during feeding is one of the top causes of gas pain, and small changes to technique can prevent it.
If you’re bottle feeding, paced feeding dramatically cuts down on air swallowing. Hold your baby in an almost upright position, supporting their head and neck. Keep the bottle sideways and flat so the nipple is only half full of milk. Don’t force the nipple into the mouth. Instead, touch it to your baby’s cheek or upper lip and wait for their mouth to open wide. Once they latch, resist the urge to tilt the bottle up or lean the baby back. When your baby needs a break, lower the bottle so the nipple empties but stays in the mouth, then bring it back up once they start actively sucking again. This mimics the natural flow of breastfeeding and prevents your baby from gulping air along with milk.
Burping during and after feeds is basic but essential. Try burping at natural pause points (when switching breasts, or every ounce or two from a bottle) rather than only at the end. Hold your baby upright against your chest or sitting on your lap with your hand supporting their chin, and gently pat or rub their back.
Dietary Factors for Breastfed Babies
If you’re breastfeeding, your diet can sometimes play a role, though the evidence is more limited than many people assume. Cow’s milk protein is the most commonly reported trigger for gas and fussiness in breastfed newborns. Dairy and soy allergies are the most frequent allergens for infants. Some mothers also report that cruciferous vegetables (broccoli, kale, cabbage), onions, garlic, beans, and caffeine seem to increase their baby’s discomfort, though no specific foods have been scientifically proven to cause gas in all infants.
If you suspect a food connection, try eliminating cow’s milk products for two to three weeks and see if symptoms improve. This is the most evidence-backed dietary change. Beyond that, keeping a food diary can help you spot patterns, but don’t restrict your diet broadly without good reason.
Formula Switches
For formula-fed babies with persistent gas or fussiness, a partially hydrolyzed (often labeled “gentle” or “sensitive”) formula may help. These formulas use protein chains that are partially broken down, making them easier to digest. If your baby has a confirmed cow’s milk protein allergy, a fully hydrolyzed or elemental formula is necessary, but these are expensive and should only be used when there’s a clear medical reason. Talk to your pediatrician before switching formulas, since frequent changes can sometimes make digestive issues worse.
Simethicone Drops
Over-the-counter gas relief drops containing simethicone are widely available and considered safe for newborns. Simethicone works by breaking up gas bubbles in the stomach, making them easier to pass. The standard dose for infants under two years (or under 24 pounds) is 0.3 mL, which contains 20 mg of simethicone. You can give it after meals and at bedtime, up to 12 times per day.
That said, simethicone works better for some babies than others. It’s worth trying for a few days to see if it makes a noticeable difference, but don’t be surprised if the effect is modest. It’s a safe option but not a guaranteed one.
Why Gripe Water Is Risky
Gripe water is one of the most popular remedies parents reach for, but pediatricians generally don’t recommend it. It typically contains fennel, ginger, sodium bicarbonate, and various flavorings. The core problem is that gripe water isn’t regulated by the FDA, and no scientific evidence confirms it’s safe or effective. Because herbal remedies don’t undergo the same oversight as food or medicine, there’s no guarantee that any given product meets basic quality or safety standards.
The risks aren’t theoretical. Multiple brands of gripe water have been recalled over the years. One recall followed a six-week-old infant developing a parasitic infection from contaminated water in the product. Another involved an undissolved ingredient that posed a choking hazard. In a separate case, bacterial contamination caused septic shock in a nine-month-old. Given the lack of proven benefit and real potential for harm, simethicone drops are a safer over-the-counter choice if you want to try something.
Probiotics for Colic
One intervention with growing clinical support is a specific probiotic strain (sold under brand names like BioGaia) given as drops. In a randomized, double-blind trial published in The Journal of Pediatrics, breastfed infants with colic who received five drops daily for 21 days cried and fussed significantly less than those given a placebo. By day 21, babies in the probiotic group averaged about 60 minutes of crying per day compared to 102 minutes in the placebo group. Three times as many babies in the probiotic group achieved at least a 50% reduction in crying.
The evidence is strongest for breastfed babies. Results in formula-fed infants have been more mixed. If your baby has colic and you’ve tried the basics without enough improvement, probiotic drops are a reasonable next step to discuss with your pediatrician.
Symptoms That Need Immediate Attention
Most newborn stomach pain is harmless and temporary, but a few warning signs require urgent care. Bright green vomit (bile) can signal an intestinal blockage and is a surgical emergency. Any baby under one month old with a fever, vomiting, poor feeding, excessive sleepiness, or unusual skin color needs to be seen right away.
Bloody stools, a hard and distended belly that doesn’t soften between crying episodes, and refusal to eat are also red flags. Projectile vomiting (forceful enough to travel across the room) in a baby under three months old can indicate a condition called pyloric stenosis, where the stomach outlet thickens and blocks food from passing through. If your newborn is losing weight or failing to gain weight despite adequate feeding, that also warrants a prompt evaluation.
