How to Help a Gassy Newborn: What Actually Works (and What Doesn't)
In short
A gassy newborn is almost always a normal newborn — most babies swallow air when they feed or cry, and their gut is still learning its job. The moves that actually help are simple and free: burp during and after every feed, hold your baby upright for 15-30 minutes after, bicycle their legs on their back, use tummy time between feeds, feed before the crying starts, and slow the flow of the bottle. Skip the gripe water. Gas drops are safe but not proven to help. Call the doctor for a fever, blood in stool, projectile vomiting, or crying you cannot console.
There is a specific look a gassy newborn gets: knees pulled up, red face, that quiet grunt that turns into a wail, and then — sometimes — a fart that resets the whole room. It is one of the most common calls to pediatricians in the first three months, and it is almost always exactly what it looks like: a brand-new digestive system doing brand-new work.
The good news is that the moves that actually help are simple, free, and a little boring. The tricky part is knowing which ones the pediatric guidance actually backs, which ones to skip, and when a gassy cry is something else. Here is what the American Academy of Pediatrics, Cleveland Clinic, and the Children's Hospital of Philadelphia say — and nothing invented in between.
01Why newborns are so gassy
Gas is a normal byproduct of eating and breathing, and newborns are unusually good at making extra of it. The Cleveland Clinic explains that babies "develop gas naturally by swallowing extra air during bottle feeding, breastfeeding, crying, or pacifier use," and that discomfort "typically peaks during the first four months." The Children's Hospital of Philadelphia adds that intestinal bacteria ferment undigested milk, creating gas that comes out as farts — "often a sign of healthy gut development."
So the goal is not to eliminate gas — that is not possible, and it is not the problem. The goal is to help the air your baby has already swallowed get out sooner, and to keep them from swallowing quite so much of it in the first place.
02The signs your baby is actually gassy
Cleveland Clinic lists the classic signs: "excessive fussiness," "scrunched facial expressions," "increased squirming," "legs pulled toward chest," and reduced eating and sleeping. Norton Children's adds a helpful tell: with gas, "discomfort improves after passing gas" and the baby is "easily consoled." If a good burp or fart flips the mood, gas was the story.
03What actually helps — the moves that work
None of what follows needs equipment or an app. This is the pediatric-guidance version of the toolkit.
The gas-relief toolkit
- Bicycle the legs. With your baby on their back, gently cycle their legs like they are pedaling. The AAP's HealthyChildren.org recommends laying baby on their back and moving legs in bicycling motions, and Cleveland Clinic confirms the move "aids gas and bowel movement."
- Burp during, not just after. The AAP is direct: "Burp your baby during, as well as after, each feeding." Cleveland Clinic's Dr. Amy Sniderman puts the timing simply: "Typically, we suggest pausing about halfway through a feeding to try for a burp and then again at the end."
- Hold upright for 15-30 minutes after a feed. Norton Children's recommends holding baby upright for 15 to 30 minutes after feeding. CHOP echoes it: keep the infant "upright for several minutes after feeding."
- Use tummy time between feeds. HealthyChildren.org notes that supervised tummy time "can put pressure on any gas that's thinking about settling in to be on its way out instead." CHOP suggests placing an awake baby on their belly after feeding and increasing tummy time throughout the day. (For the how, our tummy time guide covers the basics.)
- Feed before the crying starts. CHOP is specific: "Start feedings before your infant cries a long time from hunger." Cleveland Clinic explains why — "wailing causes gulping that increases air intake." A baby who is already crying will suck down a bottle like a straw.
- Slow the bottle down. Both Cleveland Clinic and the AAP recommend slow-flow nipples and, if needed, "vented, angled or collapsible" bottles to reduce air swallowing. Our full paced bottle feeding guide walks through the technique.
- Stir formula, don't shake it. "The more mixing and shaking involved, the more air bubbles get into the mix," per the AAP. Cleveland Clinic's version: stir rather than shake, then wait for bubbles to rise before feeding.
- Try a gentle belly massage or warm bath. Norton Children's suggests "gentle tummy and body massage" and "warm baths to relax muscles." Neither will hurt, and both give you something calming to do at 2 a.m.
The burp position that gets stuck burps out
CHOP has a small trick worth knowing: "If a burp feels stuck, lay baby down briefly, then return to upright position." That change of position often shakes the bubble loose when patting alone will not. If you want the three main burp holds, our how to burp a baby guide walks through each one.
04What to skip — or use with realistic expectations
This is where a lot of parenting advice goes off the rails. The over-the-counter aisle is full of things marketed for newborn gas, and the pediatric evidence for most of them is thin.
- Gas drops (simethicone). Safe, but probably not helpful. HealthyChildren.org states plainly: "we can't find definitive evidence to show that the effort and expense of infant gas drops pay off," and adds that for colic specifically, "studies suggest that simethicone does not help." Cleveland Clinic is a little more forgiving — call them "FDA-approved" and useable preventively — but if you try them and see nothing, that is a normal result, not a failed attempt.
- Gripe water. Cleveland Clinic recommends against it: "Not FDA-regulated; safety and effectiveness lack solid research backing." Skip it.
- Probiotics. CHOP is polite but clear: there is "not a lot of data" supporting probiotics for infant gas. Do not start one on your own — ask your pediatrician first.
- Rewriting a nursing parent's diet. The AAP notes that identifying food culprits is "often easier said than done," and warns against restricting a nursing parent's diet so much it becomes inadequate. CHOP is blunter: there is "no definitive correlation between mother's diet and baby's gas." Watch for patterns, but do not go on an elimination diet without guidance.
- Switching formula every few days. CHOP suggests trying a new formula for one full week before deciding — and reverting if there is no improvement. Constant switching is its own source of trouble.
05Gas or colic? How to tell the difference
Colic is not the same as gas — and calling colic "just gas" can leave parents feeling like they are doing something wrong when they are not. CHOP defines colic as "crying that lasts more than 3 hours a day for more than 3 days out of the week in an otherwise healthy infant under 3 months of age." The classic pattern is a baby who "cries or is fussy several hours a day, especially from 6 p.m. to midnight, with no apparent reason."
Norton Children's draws the practical line: a gassy baby's crying "follows feeding or occurs briefly," improves after passing gas, and the baby is "easily consoled." A colicky baby's crying is intense, happens at consistent times (usually evening), is "resistant to soothing," and — importantly — the baby is otherwise feeding and gaining weight normally. If that sounds like your evenings, our newborn witching hour and how to soothe a crying newborn guides are the next reads.
This is general information, not medical advice
Every baby is different. If your newborn's gas, crying, or feeding is worrying you, your own pediatrician is the person to call — they know your baby and your history. That is exactly what they are there for. Do not wait it out because you are afraid of being 'that parent.' Pediatricians would much rather hear from you at 10 p.m. than have you spiral until morning.
06When gas is not just gas — call the doctor
Gassiness is almost always benign. But a handful of symptoms mean the story is different. Cleveland Clinic says to contact your pediatrician if your baby has "stopped pooping or eating," "black or bloody stools," vomiting, a fever over 100.4°F/38°C, inconsolable fussiness, or any signs of an allergic reaction — rash, hives, swelling, or trouble breathing.
Norton Children's lists the ER-level red flags for the youngest babies: a fever of 100.4°F or higher in any baby under 3 months, bright green vomit, blood in vomit or stool, labored or irregular breathing, extreme sleepiness or unresponsiveness, or "hard, distended belly with inconsolable crying." Any of those, do not wait — call, or go.
07The quiet news: this doesn't last forever
CHOP's most reassuring line is a boring one: gas discomfort "typically peaks at six weeks and improves immensely by 3 months." Cleveland Clinic puts the same window at about four months. Which means the exact era where a gassy baby feels like your entire life is also the era that quietly ends on its own. The moves above just help you both get through it with fewer tears — theirs and yours.

Questions parents actually ask
Why is my newborn so gassy?
Because they are new at eating. Cleveland Clinic explains that babies swallow extra air during bottle feeding, breastfeeding, crying, and pacifier use, and their gut is still maturing. CHOP notes that gut bacteria fermenting undigested milk also creates gas — often a sign of healthy digestive development, not a problem. Discomfort typically peaks in the first four months and gets much better by three months.
What is the fastest way to relieve gas in a newborn?
The moves that work fastest are simple: bicycle the legs while your baby is on their back, burp them upright over your shoulder, and put them on their belly for a few minutes of supervised tummy time. HealthyChildren.org (the AAP), Cleveland Clinic, and CHOP all recommend those three. If a burp feels stuck, CHOP suggests laying baby down briefly, then bringing them back to upright — the position change often shakes it loose.
Do gas drops (simethicone) actually work for babies?
Probably not much. HealthyChildren.org (the AAP) states that "we can't find definitive evidence to show that the effort and expense of infant gas drops pay off," and that for colic specifically, "studies suggest that simethicone does not help." They are considered safe, so trying them will not hurt — but do not expect a dramatic change, and do not feel like you are missing something if they do nothing.
Is gripe water safe for newborns?
Cleveland Clinic advises against it, noting that gripe water is "not FDA-regulated; safety and effectiveness lack solid research backing." There are safer, better-studied moves — burping, upright holding, bicycle legs, tummy time — that do the same job.
How can I tell if it's gas or colic?
CHOP defines colic as crying that lasts more than three hours a day, more than three days a week, in an otherwise healthy baby under three months old — often clustered from 6 p.m. to midnight. Norton Children's draws the practical line: with gas, discomfort improves once your baby passes gas and they are easily consoled; with colic, the crying is intense, predictably timed, and resistant to soothing, even though the baby is feeding and gaining weight normally.
When should I call the doctor about my baby's gas?
Cleveland Clinic says to call for a fever over 100.4°F, black or bloody stools, vomiting, a baby who has stopped pooping or eating, inconsolable fussiness, or allergic-reaction signs like a rash or trouble breathing. Norton Children's adds ER-level red flags: any fever of 100.4°F or higher in a baby under three months, bright green vomit, blood in stool or vomit, labored breathing, extreme sleepiness, or a hard, distended belly with inconsolable crying.
