Spit-up after feeds, fussy evenings, a baby who arches away from the breast or bottle — if this sounds familiar, your little one may have reflux. Baby reflux is extremely common and, in most cases, completely harmless. This guide covers the typical baby reflux symptoms and remedies, plus the warning signs that mean it is time to call the doctor.
What Is Baby Reflux?
Reflux happens when milk flows back up from the stomach into the oesophagus. In babies, the muscular valve between the stomach and the oesophagus is still immature, so it does not always close properly after a feed. A little milk escaping upward is therefore normal, especially in the first months.
Most babies outgrow reflux during their first year as the valve strengthens and they spend more time upright. It is sometimes called posseting or simply spitting up, and for the majority of babies it is more laundry than emergency.
Common Baby Reflux Symptoms
- Frequent spit-up after feeds, sometimes with a little force but usually just dribbling out.
- Fussiness during or after feeds — crying, squirming, or pulling away.
- Arching the back while feeding or just after.
- Coughing, gagging, or hiccups during feeds.
- Trouble settling when laid flat soon after a feed.
- Wet burps or small vomits between feeds.
Many babies with these symptoms feed well, gain weight normally, and are otherwise happy — this is often called “happy spitting” and needs no treatment beyond practical tweaks.
Gentle Remedies That Often Help
These practical steps ease reflux for most babies. Try them one at a time and give each a few days before judging.
1. Offer smaller feeds more often
A very full stomach refluxes more easily. If you bottle feed, try slightly smaller bottles at shorter intervals. If you breastfeed, offering one breast per feed or feeding a little more often can reduce the volume sitting in the stomach.
2. Burp well during and after feeds
Trapped air increases pressure in the tummy. Pause halfway through a feed to burp, then burp again at the end. An upright position against your shoulder usually works best.
3. Keep your baby upright after feeds
Hold your baby upright — on your shoulder or in your arms — for twenty to thirty minutes after each feed. Gravity is the simplest reflux remedy there is. Avoid laying them flat, bouncing, or vigorous play straight after eating.
4. Check feeding position and flow
For bottle-fed babies, make sure the teat flow is not too fast; gulping lets in air and overfills the stomach quickly. For breastfed babies, a good deep latch reduces swallowed air. Feeding in a slightly upright position helps too.
5. Avoid tight clothing around the tummy
Tight nappies, elastic waistbands, or pressure on a full stomach can push milk upward. Keep clothing comfortably loose around the middle, especially after feeds.
6. Keep a simple symptom diary
Note when spit-up happens, how much, and what seems to trigger it. This record is genuinely useful if you later speak to your paediatrician — it turns vague worry into clear information.
When to Call the Doctor
See your paediatrician promptly if you notice any of the following:
- Poor weight gain or weight loss.
- Forceful, projectile vomiting.
- Vomit that contains blood or looks green.
- Refusing feeds or taking much less milk than usual.
- Breathing difficulties, wheezing, or chronic cough.
- Blood in the stool, or a baby who seems in real pain.
These signs can point to something more than simple reflux, such as an allergy or another condition that needs medical assessment. This article provides general information only — it never replaces your doctor’s advice. When in doubt, always check with your paediatrician.

Reassurance for Worried Parents
Baby reflux symptoms can look alarming but are usually just a messy phase. Smaller feeds, good burping, and upright cuddles after meals ease things for most families. Watch for the warning signs above, trust your instincts, and remember that this, too, passes as your baby grows.
