Your newborn is pulling their legs up, arching their back, and crying hard after a feed. Gas is one of the most common reasons babies fuss in the first few months of life. The good news is that newborn gas is normal, and most of the simple things parents already do — burping, gentle tummy massage, and holding a baby upright after feeding — genuinely help. This guide covers what causes gas, what actually works, and when a fussy, gassy baby needs a doctor instead of a home remedy.
Why Do Newborns Get So Much Gas?
Newborns swallow air during feeding, and their digestive systems are still learning how to move it through. That combination produces gas in almost every baby.
A few things make newborns especially prone to it. They spend a lot of time feeding, and any time they suck — breast or bottle — they swallow some air along with milk. Their intestines are also brand new at the job of breaking down milk and pushing waste along. The muscles that move food through the gut are still coordinating, so gas can build up and sit there instead of moving out quickly.
Some gas is simply a normal byproduct of digestion. When bacteria in the large intestine break down undigested sugars from milk, they produce gas. That happens in everyone, including adults. In a tiny baby, a small amount of gas can cause a lot of discomfort because there is not much room in there.
It is worth separating two things that often get lumped together: gas itself, and the crying that parents attribute to gas. A baby can have gas and be perfectly content. A baby can also cry hard for other reasons — hunger, tiredness, overstimulation, or just needing to be held — while also passing gas. This matters because treating the gas will not always stop the crying if gas was not the cause.
How To Help Newborn With Gas: What Actually Works
Burping, upright positioning, and gentle movement are the most reliable ways to help a gassy newborn. None of these require special products, and all of them are low-risk.
Burp during and after feeds. Do not wait until the end of a full feeding. Burp when you switch breasts, or every couple of ounces with a bottle. Some babies burp easily; others need a few minutes of gentle patting or rubbing on the back. If nothing comes up after a few minutes, it is fine to stop and try again later — not every feeding produces a burp.
Hold your baby upright for a while after feeding. Keeping a newborn upright for 20 to 30 minutes after a feed helps milk settle and can reduce the air that gets trapped. This is also standard advice for babies who spit up a lot.
Try gentle tummy massage. With your baby lying on their back, use flat fingers to rub their belly in a clockwise direction. Clockwise follows the path of the large intestine, which is the direction gas travels. Some parents find this helps; the evidence for massage specifically relieving gas is not strong, but it is safe and soothing.
Try bicycle legs. Gently move your baby’s legs in a pedaling motion while they lie on their back. This can help move gas along and often prompts a burp or a fart. Stop if your baby seems uncomfortable.
Give tummy time when awake and supervised. Light pressure on a baby’s belly while they are awake and being watched can help move gas. Never put a baby to sleep on their stomach.
Does Burping Technique Really Matter?
How you burp matters less than whether you do it consistently. There is no single correct method, and different positions work for different babies.
Common positions include holding your baby upright against your shoulder, sitting them on your lap while supporting their chin and chest, or laying them face-down across your lap. All three use gravity and gentle pressure to help air rise.
What tends to matter more is timing. Air swallowed early in a feed is easier to bring up than air that has been sitting for a while. If your baby is gulping fast, pausing to burp more often can help. If your baby feeds calmly and slowly, you may not need to burp as frequently.
One thing worth knowing: a baby who does not burp is not necessarily full of trapped gas. Some babies swallow very little air, especially when breastfeeding with a good latch. Do not spend 20 minutes pounding on a content baby’s back. A few minutes of gentle effort is enough.
Can Formula or Bottle Feeding Cause More Gas?
Bottle-fed babies can swallow more air than breastfed babies, mostly because of how the bottle delivers milk. The fix is usually about technique, not about switching formula.
Air gets swallowed when a baby sucks on a bottle that is not delivering milk fast enough, or when the nipple is the wrong size or shape. A few adjustments may help:
- Keep the bottle tilted so milk fills the nipple, not air.
- Use a nipple flow rate that matches your baby’s pace — not so slow they gulp air, not so fast they choke.
- Pause and burp every few ounces.
- Try paced bottle feeding, where you hold the bottle more horizontal and let your baby set the rhythm.
Switching formulas is rarely the answer for gas alone. If a baby is thriving and gaining weight, gas is usually not a sign that the formula is wrong. Some parents try a different formula anyway and see improvement, but it is hard to know whether the change helped or the baby simply grew out of the phase. Talk to your pediatrician before making a switch, especially if you are considering a specialty or hydrolyzed formula.
For breastfed babies, some parents wonder if something in their diet is causing gas. True food-related gas in a breastfed baby is uncommon, and eliminating foods from a nursing parent’s diet is not a first-line approach. If you suspect a reaction to something you are eating, talk to your baby’s doctor before cutting foods out.
Do Gas Drops, Gripe Water, and Simethicone Work?
Simethicone drops are the most commonly used over-the-counter gas remedy for infants. The evidence that they reliably reduce gas symptoms in babies is limited, and studies have not consistently shown a clear benefit over placebo.
Simethicone works by helping small gas bubbles join together into larger ones, which are supposedly easier to pass. In practice, many parents report it helps, and many report it does nothing. It is generally considered low-risk when used as directed, but it is not a proven fix.
Gripe water is a mix of herbs and sometimes other ingredients. Formulas vary widely, and there is no strong clinical evidence that gripe water reduces gas or colic. Some versions have contained alcohol or other ingredients that are not appropriate for newborns, so check labels carefully. Because products are not standardized, it is hard to say much about safety or effectiveness across the board.
Probiotics have been studied for colic and digestive symptoms in infants, with mixed results. Some strains have shown benefit in some trials, but findings are not consistent enough to call this an established treatment. If you want to try a probiotic, ask your pediatrician which one, if any, they recommend.
The honest position: none of these products has strong evidence behind it for newborn gas. They are widely used, and some parents find them helpful, but that is not the same as proven effectiveness.
When Is Gas a Sign of Something Else?
Most newborn gas is harmless. But persistent crying and discomfort can sometimes point to a different issue, and a few signs mean you should call your baby’s doctor.
Colic is defined by the “rule of threes”: crying for more than three hours a day, more than three days a week, for more than three weeks, in an otherwise healthy baby. Colic is not the same as gas, though the two often overlap. The cause of colic is not fully understood, and it is not simply a gas problem.
Some babies have a sensitivity to cow’s milk protein, which can cause gas, fussiness, blood in the stool, or poor weight gain. This is a real condition, but it is not common, and it should be diagnosed by a doctor — not assumed because a baby is gassy.
Signs that warrant a call to your pediatrician include:
- Crying that cannot be soothed and lasts for hours
- Vomiting that is forceful or green
- Blood in the stool
- Poor weight gain or feeding less than usual
- A firm, swollen belly
- Fever in a baby under three months
- Fewer wet diapers than usual
These signs do not always mean something serious, but they are worth checking rather than waiting out.
Will Newborn Gas Just Go Away On Its Own?
Yes, for most babies. Gas and the fussiness that comes with it tend to peak in the first few months and improve as the digestive system matures.
By around three to four months, many babies have fewer gas-related problems. Their gut muscles coordinate better, they swallow less air as feeding skills improve, and they spend more time upright and moving. Some babies improve sooner; some take longer.
That timeline is a general pattern, not a promise. If your baby’s gas and crying seem to be getting worse rather than better, or if you are worried for any reason, that is a good reason to check in with your pediatrician. You do not need to wait for a milestone to ask.
Frequently Asked Questions
How do I know if my newborn has gas or colic?
Gas usually comes with a hard belly, passing gas, and relief after burping or passing stool. Colic is defined by crying for more than three hours a day, more than three days a week, for more than three weeks, and is not simply a gas problem.
Does simethicone actually help newborn gas?
The evidence is limited, and studies have not consistently shown a clear benefit over placebo. It is generally considered low-risk when used as directed, but it is not a proven treatment.
Can I give my newborn gripe water for gas?
There is no strong clinical evidence that gripe water reduces gas or colic in newborns. Formulas vary, and some have contained ingredients not appropriate for infants, so check with your pediatrician first.
How long does newborn gas last?
Gas and related fussiness typically peak in the first few months and improve as the digestive system matures, often by around three to four months. This is a general pattern, not a fixed timeline.
