A newborn who grunts, squirms, goes red, pulls their knees up and then brings up a mouthful of milk can look like a baby in real trouble. Almost always, it isn’t: wind and a little spit-up are part of the standard newborn package, as their brand-new digestive system learns its job. Here’s what’s normal, how to help things along, and the handful of signs that mean it’s worth a call.
Why newborns are so windy
A newborn’s gut is immature and still finding its rhythm, and along the way they swallow air — during feeds, and especially while crying. That air has two ways out: up as a burp, or down as gas. Add a digestive system practising for the first time, and grunting, squirming and the odd trumpet from the other end are simply the soundtrack of the early weeks.
Burping: how and when
Burp your baby partway through a feed (when you swap breasts or pause a bottle) and again at the end. Three positions cover most babies:
- Over your shoulder, upright, patting or rubbing upward.
- Sitting on your lap, leaning slightly forward with their chin and chest supported by your hand.
- Face-down across your lap, with gentle pats.
Not every feed produces a burp. If none comes after a few minutes and your baby seems comfortable, just move on — breastfed babies often swallow less air and may need less burping than bottle-fed ones.
Relieving trapped gas
When wind seems stuck and uncomfortable, a few moves usually help:
- Bicycle legs — gently cycle their legs while they’re on their back.
- A clockwise tummy massage, following the direction of the gut.
- Supervised tummy time while awake, and holding them upright against you.
- A calm, paced feed with a good latch, or the right bottle-teat flow, so less air goes down in the first place; keep your baby fairly upright while bottle-feeding.
Anti-colic bottles help some babies. Gripe water and “gas drops” are popular, but the evidence is mixed — check with your pediatrician or health visitor before using them.
Spit-up, reflux, or vomiting?
These look similar but aren’t the same:
- Spit-up (posseting) is small, effortless milk that comes up after feeds. A “happy spitter” — gaining weight, content between feeds — is normal. It often peaks around four months and fades as your baby sits up and starts solids.
- Reflux is frequent spit-up. On its own it’s just laundry; it only needs treating (then called reflux disease) if it causes pain, feeding refusal, or poor weight gain.
- Vomiting is forceful and larger, with a distressed baby — a different thing from a lazy dribble of milk.
To cut down spit-up, try smaller, more frequent feeds, burp well, and hold your baby upright for 20–30 minutes afterwards. Don’t tilt or prop the cot mattress to raise their head — inclined sleep surfaces are unsafe; the safe-sleep rules still come first.
When to call a professional
Contact your pediatrician, family doctor, or health visitor — urgently for the first two — if you see:
- Projectile vomiting that shoots out forcefully, especially if it keeps happening
- Vomit that is green or yellow (bile) or has blood in it
- Spit-up alongside poor weight gain, feed refusal, or arching and crying in pain with feeds
- Frequent coughing, gagging or breathing trouble around feeds
- Signs of dehydration — far fewer wet diapers, a dry mouth, an unusually sleepy baby
- A hard, swollen belly with no poop and vomiting, which can signal a blockage
This is general information, not medical advice. Every baby is different — if your baby’s spitting up or discomfort worries you, ask the people who know your baby’s history.
Most wind settles with nothing more than time and a few burps, and a lot of it traces back to how feeds go in: a calm, well-latched, unhurried feed swallows less air than a frantic one. Trapped gas can also pile onto the evening fussiness that’s already par for the course early on. Jotting down feeds and the big spit-ups makes the pattern clear — and turns the doctor’s “how often, and how much?” into an answer.
