Is it normal for my baby to bring up milk after every feed?

Yes, for many babies it is. Frequent spitting up is normal as long as your baby is content, feeding well, and gaining weight along their growth curve. Doctors often call these babies 'happy spitters'. The mess is inconvenient but the reflux itself is not harmful and will settle with time.

Should I raise the head of the cot to help reflux?

No. Safe sleep guidance is that babies should always sleep on their backs on a flat, firm surface, and raising the cot or using wedges has not been shown to reduce reflux but does increase the risk of the baby sliding into an unsafe position. Holding your baby upright for a while after feeds, while awake, is the safer option.

Does my baby need reflux medication?

Usually not. Acid-suppressing medicines do not reduce how often babies bring up milk, and studies show they do not help crying or fussiness in babies without true GORD. They are reserved for babies with confirmed reflux disease causing pain, poor growth, or feeding refusal, and should be reviewed regularly. Never start or stop these medicines without medical advice.

Could it be a milk allergy rather than reflux?

Sometimes. Cow's milk protein allergy can cause reflux-like symptoms along with eczema, loose or bloody stools, poor weight gain, or wheeze. If your doctor suspects it, a two-to-four-week trial without cow's milk protein, followed by reintroduction, is the usual way to find out.

Reflux in Infants

Also known as: Infant reflux, Posseting, Infant GER

Reflux in infants is the effortless bringing up of milk after feeds, sometimes called posseting or spitting up. It happens because the muscular valve between a baby's stomach and food pipe is still developing, so milk easily flows back up, especially when the stomach is full or the baby is lying flat. Reflux is extremely common, affects at least half of all babies, and in most cases is a normal stage of development rather than a disease. It usually peaks around four months and settles by the time a baby is sitting up and eating solids, almost always by 12 to 18 months. A small number of babies have gastro-oesophageal reflux disease (GORD), where reflux causes pain, poor weight gain, or feeding problems and needs treatment. Knowing the difference helps parents avoid unnecessary worry and medication.

At a Glance

Common symptoms: Bringing up milk during or shortly after feeds, often without distress, Hiccups, swallowing, or gulping noises after feeds, Coughing or occasional gagging after feeding
Main treatments: No treatment is needed for a 'happy spitter' who is gaining weight well; reassurance and time are the main approach, Smaller, more frequent feeds and gentle winding during and after feeds, Holding the baby upright for 20 to 30 minutes after feeds
Category: Pediatric · Very common; affects around half of all babies in the first months of life, and the great majority outgrow it by their first birthday
See a doctor if: Vomiting that is forceful (projectile), green or yellow, or contains blood

Symptoms

Bringing up milk during or shortly after feeds, often without distress

Hiccups, swallowing, or gulping noises after feeds

Coughing or occasional gagging after feeding

Crying, arching the back, or pulling away during feeds (in more troublesome reflux)

Unsettled behaviour when laid flat after a feed

Poor weight gain, refusing feeds, or frequent chest infections (signs of GORD rather than simple reflux)

Causes

An immature lower oesophageal sphincter that opens easily
A liquid diet and lots of time spent lying flat
A small stomach that fills quickly, especially with large or fast feeds
Swallowing air during feeds, which pushes milk back up when burped
Cow's milk protein allergy, which can mimic or worsen reflux in some babies

Risk Factors

Premature birth
Overfeeding or very fast feeding from a bottle
Neurological conditions such as cerebral palsy
A family history of reflux or food allergies
Exposure to tobacco smoke
A hiatus hernia or other anatomical differences (uncommon)

Diagnosis

A detailed feeding history and examination, with weight and growth plotted on a chart
Reassurance without tests when the baby is thriving and content (the most common outcome)
A trial of thickened feeds or, in breastfed babies, a maternal dairy-free diet if allergy is suspected
Specialist tests such as pH monitoring, endoscopy, or a barium study only when symptoms are severe or unusual

Treatment

No treatment is needed for a 'happy spitter' who is gaining weight well; reassurance and time are the main approach
Smaller, more frequent feeds and gentle winding during and after feeds
Holding the baby upright for 20 to 30 minutes after feeds
Thickened formula or a prescribed thickener for bottle-fed babies, under guidance
A trial of eliminating cow's milk protein (from the mother's diet if breastfeeding, or a hydrolysed formula) if allergy is suspected
Acid-suppressing medication (such as omeprazole) only for diagnosed GORD with pain, poor growth, or complications, and reviewed regularly by a doctor
Supportive: checking bottle teat flow rates and feeding positions, and avoiding tight nappies or pressure on the tummy after feeds

Prevention

Avoid overfeeding; follow the baby's hunger cues rather than finishing every bottle
Burp your baby gently partway through and after each feed
Keep your baby upright after feeds, but always place them on their back to sleep on a flat surface
Do not smoke around your baby
Avoid bouncing or vigorous play straight after feeding

When to See a Doctor

Vomiting that is forceful (projectile), green or yellow, or contains blood
Poor weight gain, refusing feeds, or fewer wet nappies than usual
Persistent crying, arching, or distress with feeds
Vomiting that starts after 6 months of age or continues beyond 12 months
Breathing problems, repeated chest infections, blood in the stool, a swollen tummy, or a baby who seems unwell or floppy
