It can seem like newborns spend half their lives hiccuping. After feeds, between feeds, while sleeping, while playing – the small, rhythmic jerks come several times a day, sometimes lasting 15 to 30 minutes at a stretch.
Most adults find their own hiccups uncomfortable enough that they assume the baby must feel the same way.
Newborn hiccups are completely normal, almost never bother the baby, and have a specific anatomical explanation.
Here is what is happening, why it happens so often at this age, and what to do (and not do) about it.
Why Newborns Get Hiccups So Often
Hiccups are caused by sudden involuntary contractions of the diaphragm – the dome-shaped muscle that drives breathing.
Each contraction pulls air sharply into the lungs, and a fraction of a second later the vocal cords snap closed, producing the characteristic ‘hic’ sound.
Newborns hiccup far more than adults for two main anatomical reasons:
Immature Diaphragm Control
The neural pathways controlling the diaphragm are still developing in the first months of life.
The diaphragm tends to fire more readily and less smoothly in response to even small stimuli – a feeding, a change in body position, a temperature shift.
Adult diaphragms ignore these triggers; newborn diaphragms react to them.
Immature Lower Esophageal Sphincter (LES)
The LES is the muscle that closes off the top of the stomach from the esophagus. In newborns, this muscle is weak and often does not close fully after feeds.
Stomach contents – including swallowed air and small amounts of milk – can press up against the diaphragm from below, triggering the contractions.
This is why newborn hiccups are most common right after feeds.
The combination of a stomach full of milk and air, an under-toned LES, and a sensitive diaphragm is essentially a perfect setup for hiccuping.
Did My Baby Hiccup in the Womb?
Yes. Most mothers feel their baby hiccup in utero during the third trimester – a rhythmic, regular tapping that goes on for several minutes.
This is the same diaphragm activity that produces post-birth hiccups, and it is considered an important part of respiratory development in the womb, helping to strengthen the diaphragm in preparation for breathing.
The frequency of newborn hiccups in the first months is essentially a continuation of this in-utero activity, gradually settling as the diaphragm matures.
Are Hiccups Uncomfortable for the Baby?
In nearly all cases, no. Most newborns are completely unbothered by hiccups. They will hiccup happily through naps, feeds, and play with no sign of distress. Many babies sleep right through extended hiccup bouts.
If your baby seems genuinely upset by hiccups – crying, arching their back, vomiting – that points more toward an issue like reflux than the hiccups themselves being painful.

What Triggers Hiccups in Newborns
The most common triggers are:
- Feeding too quickly – the rapid flow can trap air in the stomach
- Overfeeding – a very full stomach presses upward on the diaphragm
- Swallowing air during a feed – common with poor latch or bottle nipple flow
- Sudden temperature changes – cold air against warm skin can trigger them
- Excitement or laughter once social smiling and laughter begin
Identifying your baby’s main triggers makes prevention easier than treatment after the fact.
How to Stop Newborn Hiccups Gently
Pause the Feed and Burp
If hiccups start during a feed, pause and burp the baby. Releasing any trapped air reduces stomach pressure on the diaphragm and often stops hiccups quickly.
Try a 5-minute pause if the hiccups persist before resuming.
Change Positions
Holding your baby upright for 10 to 15 minutes after feeds helps the LES stay closed and reduces hiccup frequency significantly.
The upright position also allows any swallowed air to rise and be burped out before it can trigger a diaphragm contraction.
Offer the Pacifier
Sucking on a pacifier can sometimes interrupt the rhythm of hiccups by promoting relaxation in the diaphragm.
This works better in some babies than others and is worth trying when other techniques have not worked.
Offer a Small Feed
Counterintuitively, a small amount of milk can sometimes stop hiccups by triggering a swallow reflex that interrupts the diaphragm pattern.
Do not use this if hiccups started during a feed – overfeeding is more likely to be the cause.
Just Wait
In most cases, the simplest approach is the best one.
Newborn hiccups almost always resolve on their own within 10 to 20 minutes.
If the baby is not distressed, no intervention is needed.
What Not to Do
Many traditional hiccup remedies for adults are unsafe or ineffective for newborns:
- Never give water – water can interfere with feeding and is not recommended for babies under 6 months
- Never try to scare them – startling techniques are inappropriate for newborns
- Do not hold their breath or cover their face in any way
- Do not apply pressure to the chest or abdomen
- Avoid gripe water or other folk remedies without your pediatrician’s approval – many contain ingredients not safe for newborns
The American Academy of Pediatrics emphasizes that newborn hiccups are a normal developmental phenomenon that rarely needs intervention.
How to Reduce Hiccup Frequency
Prevention is more practical than cure.
To reduce how often your baby hiccups:
- Feed before your baby gets very hungry – frantic feeding leads to more air swallowing
- Keep feedings calm and unhurried
- Burp frequently – once mid-feed and once at the end is a good baseline
- Hold upright for at least 10 to 15 minutes after every feed
- For breastfed babies, check the latch – clicking sounds or visible air swallowing during feeds indicate an issue worth addressing
- For bottle-fed babies, try a slower-flow nipple if hiccups follow most feeds

When Do Newborn Hiccups Stop?
Hiccup frequency drops significantly between 4 and 6 months of age, as the diaphragm and LES mature.
By around 12 months, most babies hiccup at roughly the same frequency adults do – occasional, not daily.
If your baby’s hiccups are getting noticeably worse rather than better as they get older, or if hiccups are accompanied by other symptoms, it is worth a check with your pediatrician.
When to Call the Doctor
Hiccups themselves almost never warrant medical attention.
But contact your pediatrician if:
- Hiccups consistently last longer than 2 hours
- Hiccups are accompanied by frequent vomiting or back-arching during or after feeds
- Your baby seems to be in genuine distress during hiccups
- Hiccups disrupt feeds significantly enough that your baby is not eating well
- There are signs of poor weight gain or other digestive issues
These signs can sometimes point toward gastroesophageal reflux disease (GERD), which is different from typical infant spit-up and may benefit from treatment.
The Mayo Clinic has detailed information on distinguishing normal infant reflux from GERD.
Frequently Asked Questions
Can I let my baby sleep with hiccups?
Yes. Hiccups do not interfere with sleep for most babies, and there is no need to wake them or try to stop the hiccups before they fall asleep.
Are hiccups a sign of overfeeding?
They can be one indicator, especially in bottle-fed babies. If hiccups follow nearly every feed and are accompanied by spit-up, try slightly smaller feed volumes and more frequent burping.
Why does my baby hiccup the moment they finish a feed?
A full stomach pressing against the immature diaphragm is the most common trigger. Holding the baby upright for 10 to 15 minutes after feeds significantly reduces post-feed hiccups.
The Bottom Line
Newborn hiccups are loud, frequent, and completely normal.
They almost never bother the baby, they have a clear anatomical explanation, and they resolve on their own as the diaphragm matures over the first 4 to 6 months.
Resist the urge to use adult hiccup remedies, focus on prevention through good feeding habits, and trust that this phase passes.
