Stomach Ache in Babies: Causes, Symptoms & Treatment
Worried about your baby's tummy pain? This parent's guide covers the most common causes of stomach ache in babies — gas, colic, constipation and more — how to spot the symptoms, safe home remedies to ease discomfort, and the warning signs that need a doctor.
Stomach Ache in Babies: Causes, Symptoms & Treatment
A baby can't say "my tummy hurts," but they have plenty of ways of showing it. Here's what's usually behind it, how to spot it, what you can safely do at home, and when to call the doctor.
01 How to tell your baby has a stomach ache
Babies can't describe pain, so you read the body language instead. None of these signals on their own guarantee a stomach ache, but a cluster of them usually points that way.
Common signs to watch for
- Pulling knees to the chest, repeatedly, as though trying to ease pressure on the belly.
- A hard or bloated tummy that feels tight when you touch it gently.
- Unusual fussiness or crying, especially during or after feeds.
- Arching the back while crying, which often signals gas discomfort.
- Refusing feeds or pulling away after starting.
- Passing more or less gas than usual, sometimes with visible straining.
- Changes in stool such as diarrhoea, harder stools, or unusual colour.
You know your baby better than anyone. If something feels off even without a clear symptom, trust that instinct. It's usually right.
02 The most common causes
In most cases, a baby's stomach ache comes from one of a handful of familiar, manageable causes. Here's what's usually going on.
Trapped gas
The most frequent culprit. Babies swallow air during feeding, and when it gets trapped in the digestive system it causes bloating, discomfort and that distinctive fussy crying. Bottle-fed babies tend to swallow more air, but it happens with breastfed babies too. Proper burping after every feed helps a lot.
Colic
Colic is the name for intense, prolonged crying (usually more than three hours a day, more than three days a week) in an otherwise healthy baby. Nobody knows exactly what causes it, but gut discomfort is likely part of the picture. It typically peaks around six weeks and eases by three to four months. It's exhausting for parents, but it does pass. The American Academy of Pediatrics' parenting site has reliable, up-to-date information on colic if you want to read further.
Constipation
Less common in breastfed babies but something to watch for once solid foods start. Hard, infrequent stools, straining, and a fussy baby who seems uncomfortable between bowel movements are the usual signs. A little extra water for older babies and the right pace of introducing solids often sort it out.
Overfeeding
It's an easy mistake, especially with bottle feeding. Too much milk too fast overwhelms a small stomach and causes discomfort, spit-up and gas. Smaller, more frequent feeds are gentler on the system than fewer, larger ones.
Food sensitivities
Some babies react to certain proteins in formula or, via breastmilk, to something in the mother's diet. Cow's milk protein is the most common trigger. If you notice a pattern of fussiness or digestive upset after feeds, mention it to your paediatrician, who can guide you on whether an elimination approach or a formula change is worth trying.
Stomach bugs
A viral gastro infection can cause tummy pain alongside vomiting and diarrhoea. These are usually short-lived but can dehydrate a baby fast, so keeping up fluids and watching for signs of dehydration is important. During monsoon season the risk goes up; our monsoon baby care guide covers the hygiene habits that help prevent these.
"Most baby tummy aches are gas, and most gas passes. The hard part isn't fixing it. It's staying calm while you wait."
03 How to ease a baby's stomach ache at home
For the common, mild causes like gas and minor discomfort, gentle home measures often do the job. None of these are cures; they're comfort measures while the discomfort resolves on its own.
Gentle tummy massage
With warm, clean hands, massage your baby's tummy in slow, gentle clockwise circles. This follows the direction of the digestive system and can help move trapped gas along. Keep it light, and stop if your baby seems uncomfortable with the pressure.
Bicycle legs
Lay your baby on their back and gently move their legs in a cycling motion. This simple trick is surprisingly effective at releasing trapped gas and easing belly pressure. Most babies tolerate it well, and many seem to enjoy it.
Hold upright after feeds
Keeping your baby upright for 15 to 20 minutes after feeding lets gravity help the milk settle and any air bubbles rise for burping. It reduces both gas and reflux discomfort.
A warm compress
A warm (never hot) cloth or a warm-water bottle wrapped in a towel placed gently on the tummy can soothe cramping. Always test the temperature against your own skin first, and never leave a compress unattended on a baby.
Skin-to-skin contact
Sometimes the simplest comfort is the most powerful. Holding your baby close, skin to skin, calms them and can ease the tension that makes stomach discomfort worse. The warmth of your body and your heartbeat genuinely help.
Never give your baby any over-the-counter medication, gripe water, or herbal remedy without your doctor's specific advice. What's marketed as safe isn't always tested for babies, and a paediatrician's recommendation is the only one that counts.
04 How to reduce stomach aches from happening
You can't prevent every tummy ache, but a few habits make them less frequent.
Burp thoroughly after feeds
Take your time with this. A good burp after every feed, and sometimes mid-feed, clears the air that would otherwise become trapped gas. Hold the baby upright against your shoulder or sit them on your lap, support the chin, and pat gently.
Feed at a calm pace
A hurried feed means more swallowed air. For bottle feeding, use a slow-flow nipple suited to your baby's age and hold the bottle at an angle that keeps the nipple full of milk, not air. For breastfeeding, a good latch reduces air intake.
Dress them comfortably
Tight waistbands and snug clothing around the belly can add pressure on a full stomach. Loose, soft cotton with a gentle elastic or a relaxed fit is more forgiving after a feed, especially for babies prone to gas. If you're choosing everyday clothes, our guide on why comfort matters covers why fabric and fit make a real difference, and the best fabric for sensitive baby skin helps if skin sensitivity is part of the picture.
Introduce solids gradually
When the time comes, new foods should arrive one at a time, in small amounts, with a few days between introductions. This lets you spot any food that doesn't agree, and it gives a small digestive system time to adjust. India's National Health Portal has general guidance on infant feeding practices if you want an official reference.
05 When to see a doctor
Most baby stomach aches are mild and resolve with time and gentle comfort. But some signs need a doctor's attention promptly. Don't wait these out.
See your paediatrician if your baby has:
- Severe or inconsolable crying that doesn't ease with any comfort measure
- A fever alongside the stomach pain
- Vomiting that won't stop or appears forceful
- Blood in the stool or very dark, tarry stools
- Signs of dehydration: fewer wet nappies, dry mouth, no tears, unusual drowsiness
- A visibly swollen, rigid belly that feels hard to the touch
- Discomfort that lasts more than a day without improving
- Any change that simply doesn't feel right to you as a parent
Trust your instinct here. If you're worried, call your doctor. A reassuring answer from a professional is never a wasted call.
