Newborn gas is one of the most common reasons babies cry, squirm, and seem uncomfortable — especially during or after feeding. If your baby pulls their legs toward their tummy, arches their back, or becomes fussy for no clear reason, trapped gas may be the cause.
The good news is that gas in newborns is completely normal and usually improves with simple care techniques. In this guide, you’ll learn what causes gas in newborns, how to recognize the symptoms, safe ways to relieve gas, and when to seek medical advice.
What Causes Newborn Gas?
Gases in newborns happens mainly because a baby’s digestive system is still developing and learning how to process milk. Some of the most common causes include:
1. Swallowing Air During Feeding
Babies often swallow air while breastfeeding or bottle-feeding, especially if the latch isn’t deep enough or the bottle nipple flow is too fast. This swallowed air later causes gas in newborns.
2. Feeding Too Quickly or Overfeeding
Fast feeding can trap air in your baby’s stomach, leading to gas discomfort. Overfeeding can also stretch the tummy and worsen gas symptoms in newborn.
3. Immature Digestive System
A newborn’s gut muscles are still coordinating digestion. This immaturity naturally causes gas buildup, making gas in newborns is very common in the first months.
4. Formula Sensitivity or Dietary Reactions
Some babies react to certain formula ingredients. Breastfed babies can occasionally react to foods in a mother’s diet, which may increase newborn gas in sensitive infants.
Symptoms of Newborn Gas
Common signs of gas in newborns include:
- Crying or fussiness after feeding
- Pulling knees toward the chest
- Arching the back
- A firm or bloated tummy
- Passing gas frequently
- Difficulty settling or sleeping
Gas causing discomfort in newborns often increases in the evening hours, which explains why some babies seem harder to soothe at night.
How to Relieve Newborn Gas
There are several gentle and effective ways to relieve gas in newborns naturally and safely.
1. Burp Your Baby Often
Burping helps release swallowed air before it travels into the intestines and becomes painful gas. Burp your baby:
- During feeding breaks
- After every feeding
For step-by-step instructions, see our full guide on how to burp a newborn.
2. Try Upright Feeding Positions
Keeping your baby upright during feeds reduces air intake and lowers the risk of gas in newborns. For bottle-fed babies, ensure the nipple stays full of milk to avoid air swallowing.
3. Use Gentle Tummy Massage
Massaging your baby’s tummy in clockwise circles helps move trapped gas through the digestive tract and eases newborn gas discomfort.
4. Bicycle Your Baby’s Legs
Gently moving your baby’s legs in a bicycling motion can stimulate bowel movement and relieve newborn gas pressure.
5. Hold Baby Upright After Feeding
Keeping your baby upright for 15–20 minutes after feeding allows gravity to help gas escape naturally, reducing spit-up and newborn gas buildup.
6. Offer a Warm Bath
Warm water relaxes abdominal muscles and may help your baby pass gas more comfortably when newborn gas is causing fussiness.
Is Newborn Gas Painful?
Newborn gas can be uncomfortable but is rarely dangerous. Most babies experience gas during the first few months of life while their digestive systems mature. As long as your baby is feeding well, gaining weight, and otherwise healthy, newborn gas is typically nothing to worry about.
Gas vs. Colic: What’s the Difference?
Sometimes newborn gas symptoms overlap with colic or reflux. If your baby cries excessively for more than three hours a day, three days a week, and seems difficult to soothe, talk to your pediatrician.

Do Gas Drops Work for Newborn Gas?
Over-the-counter gas drops containing simethicone are commonly used and generally considered safe. However, they don’t work for every baby and may not significantly reduce newborn gas in all cases.
Always consult your pediatrician before giving your baby any medication.
Can a Mother’s Diet Cause Newborn Gas?
In most cases, a mother’s diet does not affect digestion significantly. However, some babies may be sensitive to dairy, caffeine, or spicy foods, which can sometimes increase newborn gas symptoms. If you suspect a food trigger, keep a food diary and consult your doctor before making changes.
How Long Does Newborn Gas Last?
Newborn gas usually improves as your baby’s digestive system matures — often by 3 to 4 months of age. During this time, consistent burping, proper feeding positions, and gentle tummy massage can make a big difference.
According to the American Academy of Pediatrics, newborn gas is common as a baby’s digestive system matures.
When Should You See a Doctor?
Contact your pediatrician if:
- Your baby refuses feeds
- Vomiting is forceful or persistent
- Blood appears in stool
- Weight gain is poor
- Crying seems severe or unusual
Trust your instincts — it’s always okay to seek medical reassurance.
Final Thoughts
Newborn gas is a normal and temporary part of early life. While it can be stressful to watch your baby struggle, simple techniques and patience can provide real relief. With time, your baby’s digestion will mature, and newborn gas discomfort will ease naturally.
