Yes, hiccups in newborns are completely normal and extremely common. Most newborns hiccup multiple times a day, with the average episode lasting about eight minutes. Far from being a sign of distress, hiccups actually appear to play a role in your baby’s brain development.
Why Newborns Hiccup So Much
Hiccups happen when the diaphragm, the dome-shaped muscle beneath the lungs, contracts involuntarily. In newborns, the nervous system pathways that control this muscle are still maturing. The diaphragm is more easily irritated and prone to these sudden contractions than it will be later in life.
What’s remarkable is that hiccups aren’t just a side effect of an immature system. Research from University College London found that each time a newborn hiccups, the diaphragm contraction triggers two large brainwaves followed by a third in the brain’s cortex. These electrical signals appear to help the baby’s brain learn to monitor and eventually control the breathing muscles voluntarily. The circuits that process body sensations aren’t fully developed at birth, so hiccups may serve as a kind of training exercise, helping the brain map the diaphragm and build the neural wiring needed for controlled breathing.
Hiccups Start Before Birth
Your baby was hiccupping long before delivery. Studies tracking diaphragm movements in 45 fetuses found that hiccups were actually the dominant type of diaphragm activity before 26 weeks of gestational age. If you felt rhythmic, repetitive jolts during pregnancy that were different from kicks, those were almost certainly hiccups. Their frequency drops sharply between 24 and 26 weeks of gestation as the fetus matures, with fewer episodes occurring rather than shorter ones. But they continue through the third trimester and into the first months of life.
What Triggers Hiccups in Newborns
Feeding is the most common trigger. Swallowing air during breastfeeding or bottle feeding irritates the diaphragm and sets off a hiccup spell. This happens with both breast and bottle, though it tends to be more frequent with bottle feeding, where babies can take in more air around the nipple. Eating too quickly, overfeeding, or feeding when your baby is already fussy and gulping can all increase the amount of swallowed air.
Sudden temperature changes, like undressing your baby for a diaper change, can also trigger a round of hiccups. So can excitement or crying, both of which cause irregular breathing patterns that stimulate the diaphragm.
How Long a Typical Episode Lasts
In a study measuring hiccup spells in infants, the average episode lasted about 8 minutes, though some were shorter and others stretched past 10. When researchers monitored infants continuously, babies spent roughly 2.5% of their total monitored time hiccupping. That might sound like a lot, but spread across a day it amounts to scattered short bursts that resolve on their own.
Most babies don’t seem bothered by hiccups at all. They’ll hiccup through a nap, through a feeding, even while smiling. If your baby seems content or unbothered, the hiccups are more annoying to you than to them.
What You Can Do (and What to Avoid)
The single most effective strategy is prevention. Feed your baby when they’re calm and before they become extremely hungry. A frantic, crying baby gulps more air, which makes hiccups more likely. Pausing partway through a feeding to burp your baby also helps release trapped air before it irritates the diaphragm.
If hiccups start during a feeding, stop and burp your baby, then resume once the hiccups settle. Holding your baby upright for several minutes after feeding gives air bubbles a chance to rise and escape. For bottle-fed babies, make sure the nipple flow isn’t too fast. If milk is pouring out when the bottle is tipped, your baby is swallowing extra air trying to keep up.
Equally important is knowing what not to do. Many traditional hiccup remedies used for adults are unsafe for newborns. Never give a newborn water, gripe water, sugar, or any liquid other than breast milk or formula. Don’t try to startle or scare the hiccups away. These approaches have no evidence behind them, and giving water to a young infant can be genuinely dangerous by disrupting their electrolyte balance.
When Hiccups Signal Something Else
In the vast majority of cases, newborn hiccups are harmless. But if hiccup episodes are happening constantly throughout the day, lasting 20 minutes or longer, and your baby seems uncomfortable, is spitting up excessively, or is arching their back during or after feedings, this pattern can point to gastroesophageal reflux. Stomach acid irritating the esophagus and diaphragm can trigger persistent hiccups that go beyond the normal developmental kind.
Hiccups that consistently interfere with feeding or sleeping, or that come alongside poor weight gain, are also worth bringing up with your pediatrician. These situations are uncommon, but they’re the line between normal newborn quirks and something that benefits from evaluation. For most babies, hiccups are simply the nervous system doing its job, one small contraction at a time.
