Newborn hiccups: when to worry, when to wait
Your baby has hiccupped four times today. It looks miserable. It is almost always nothing — here is the short list of reasons it matters, and the four things that actually help.
Newborn · Is This Normal
TL;DR
Newborn hiccups are normal. Babies hiccup in the womb starting around week 9 of pregnancy and continue doing it after birth, often several times a day, often after feeds. The diaphragm is immature and small triggers set it off. Hiccups rarely bother the baby — they mostly bother the parent watching. They almost always stop on their own within 10–15 minutes. Worth talking to a pediatrician only if they are accompanied by spitting up with arching, refusing to feed, or coughing.
Your two-week-old just finished feeding. Five minutes later, the hiccups start. Tiny rhythmic chest jerks, ten minutes straight, and your baby looks perfectly content while they happen.
This is the normal newborn condition. You probably felt the same hiccups in late pregnancy.
Why newborns hiccup so much
A hiccup is an involuntary contraction of the diaphragm followed by a sudden closure of the vocal cords — that quick "hic" sound. In adults it is annoying. In babies it is constant, and there is a reason: their diaphragm is still maturing, and the vagus nerve that regulates it is sensitive to almost any change in pressure, temperature, or fullness in the chest and stomach.
Specifically, three things set off newborn hiccups most often:
- Swallowed air during feeding. Fast letdown, fast bottle flow, or a poor latch all push air into the stomach alongside milk. The stretched stomach pushes up against the diaphragm and triggers a hiccup.
- Stomach distension from a big feed. A full stomach mechanically pressures the diaphragm. This is why hiccups often start a few minutes after a feed ends.
- Sudden temperature shifts. Going from a warm car to cool air, or a swaddle being removed for a diaper change. The vagus nerve responds and the diaphragm spasms.
None of these are problems. They are signs of a normal infant body still learning to regulate itself.
Do hiccups bother your baby?
Almost never. Watch your baby during a hiccup run: they keep eye contact, they do not cry, they often fall asleep through them. If they were uncomfortable, you would see arching, pulling away from the bottle or breast, or crying. Hiccups feel like a tickle to a newborn, not pain.
Where hiccups become uncomfortable is when they are interrupting a feed. A baby who keeps unlatching to hiccup, then re-latching to feed, can end up swallowing more air — which causes more hiccups. That feedback loop is the only time hiccups actually slow down a feed.
The four things that actually help
1. Burp mid-feed and after
The most reliable hiccup-stopper. Pause partway through a feed (around the 1–2 oz mark for bottle, or when switching sides for breast). Pat or rub baby's back firmly for a minute. You are releasing the air bubble before it stretches the stomach.
2. Slow the milk flow
If hiccups happen after every bottle feed, the nipple flow may be too fast. Use the slowest flow that does not frustrate your baby — typically size 0 or size 1 for the first 3 months. If hiccups happen during breastfeeding, try a "laid-back" position (mom reclined, baby on top) so milk does not gush. Paced bottle feeding reduces air swallowing significantly.
3. Smaller, more frequent feeds
If your baby hiccups after every large feed, try offering less milk more often. A 3 oz feed every 2 hours stretches the stomach less than a 5 oz feed every 4 hours. The math is the same; the diaphragm pressure is not.
4. Let them suck
A pacifier or the breast (non-nutritively) often settles a hiccup run by changing the rhythm of swallowing. The sucking pattern resets the vagus nerve activity. Most parents discover this by accident.

Our bottle feeding calculator gives an age + weight–based feed volume and pace recommendation. Useful for catching the "too big, too fast" feeds that drive hiccups.

- Holding your breath / scaring them. Not appropriate for newborns. The "startle" approach that sometimes works for adults can frighten an infant.
- Sugar water or honey. Honey is unsafe for any baby under 12 months — risk of infant botulism. Sugar water is unnecessary and offers no proven benefit.
- Giving plain water. Babies under 6 months should not drink water; it interferes with sodium balance and can be dangerous in volume. Breast milk or formula only.
- Bouncing or jostling them. Movement does not change hiccup frequency and can lead to spit-up.
The most effective non-treatment is patience. The vast majority of hiccup episodes resolve in 5–15 minutes on their own.
When hiccups are worth a call
The AAP's red flags for hiccups in infants are very narrow. Call your pediatrician if hiccups are:
- Lasting more than 1–2 hours at a stretch (rare, but worth checking)
- Happening alongside frequent forceful spit-up, especially with arching or crying — could indicate gastroesophageal reflux (GERD)
- Interrupting feeds badly enough that baby is gaining weight slowly
- Accompanied by wheezing, coughing, or any breathing difficulty
- Sudden onset in an unwell-looking baby — particularly with fever
For the typical hiccup run after a feed, in a content baby who is eating and gaining well: do nothing. They will be gone in fifteen minutes, and they will be back tomorrow, and that is exactly how it is supposed to be for the first 4–6 months.
