Gas Discomfort in Newborns
The short answer
Gas is very common in newborns because their digestive systems are immature. Signs include fussiness, pulling legs up, a hard or distended tummy, and excessive flatulence. Burping during and after feeds, bicycle leg exercises, tummy time, and gentle tummy massage can help. Gas drops (simethicone) are safe but have limited evidence of effectiveness.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
All babies have gas, but some seem more affected than others. Newborns swallow air during feeding and crying, and their immature digestive systems produce gas during normal digestion. Signs of gas discomfort include: fussiness especially after feeds, pulling legs up toward the belly, a round or firm abdomen, arching the back, and excessive passing of gas. Helpful strategies include: burping baby thoroughly during and after every feed, holding baby upright for 15-20 minutes after feeds, gentle bicycle leg movements, tummy massage in a clockwise direction, and supervised tummy time.
Gas discomfort often peaks around 4-6 weeks and then gradually improves. Continue burping techniques and other comfort measures. If gas is severe and baby is very fussy, your pediatrician may evaluate for underlying causes such as milk protein sensitivity, formula intolerance, or reflux. Probiotic drops (such as Lactobacillus reuteri) may be discussed.
Gas discomfort typically improves significantly as the digestive system matures. If it persists, discuss with your pediatrician.
Gas may recur with the introduction of new solid foods. Introduce new foods one at a time and observe your baby's response.
What Should You Do?
When to take action
- Some fussiness after feeds that resolves with burping
- Passing gas frequently without significant distress
- A slightly round belly that is soft and not painful to gentle pressure
- Improvement with age and maturity of the digestive system
- Gas discomfort seems severe and persistent despite comfort measures
- Baby is excessively fussy for hours each day (could be colic)
- You notice blood or mucus in stools along with gassiness
- Hard, distended abdomen with vomiting (especially green/bile) that could indicate bowel obstruction
- Baby is inconsolable, has a fever, or appears very ill

Related Digestive Concerns
My Baby Has Excessive Gas
Gas is incredibly common in babies and usually peaks around 6-12 weeks. While it can seem uncomfortable, most babies pass gas 15-20 times per day as their digestive systems mature. Simple techniques like bicycle legs, tummy time, and proper burping can help, and it typically improves significantly by 3-4 months.
Is It Colic or Just Gas?
Gas causes temporary discomfort that improves when baby passes gas or poops, while colic involves intense, inconsolable crying for 3+ hours at a time, at least 3 days a week, often at the same time each day. Gas is extremely common; true colic affects about 1 in 5 babies and typically starts around 2-3 weeks and resolves by 3-4 months.
Straining and Grunting to Poop (Infant Dyschezia)
Straining, grunting, and turning red during bowel movements is very common in newborns and is called infant dyschezia. It occurs because babies are learning to coordinate relaxing the pelvic floor while bearing down with the abdomen. It is NOT constipation as long as the stool is soft. It typically resolves by 3-4 months.
My Baby's Belly Looks Swollen
A rounded, slightly protruding belly is completely normal in babies and toddlers due to immature abdominal muscles and their proportionally larger organs. However, if the belly becomes suddenly swollen, feels hard and tight, or is accompanied by pain, vomiting, or changes in bowel movements, it needs medical evaluation as it could signal gas buildup, constipation, or rarely, something more serious.
My Baby Has an Anal Fissure (Blood When Pooping)
A small streak of bright red blood on the surface of your baby's stool or on the diaper is most commonly caused by an anal fissure, which is a tiny tear in the skin around the anus from passing hard stool. Anal fissures are very common in babies and toddlers and usually heal on their own with simple measures like keeping stools soft. While this is rarely serious, any blood in your baby's stool should be mentioned to your pediatrician.
Tummy Massage for Baby Gas
Gentle abdominal massage can help relieve gas and discomfort in babies by encouraging gas to move through the intestines. The technique involves gentle clockwise circular motions on the belly (following the direction of the digestive tract), the "I Love U" stroke pattern, and gentle knee-to-tummy movements. Massage also provides comforting touch that can soothe a fussy baby.
