How Long Do Newborn Hiccups Last and When to Worry

A typical episode of newborn hiccups lasts 5 to 10 minutes, sometimes a bit longer. They’re extremely common in the first months of life and almost always harmless. In fact, your baby likely started hiccuping well before birth, practicing breathing movements in the womb as early as the second trimester.

How Long a Single Episode Lasts

Most newborn hiccup bouts resolve on their own within about 5 to 10 minutes. Some episodes stretch a little longer, but even a 15- or 20-minute round of hiccups is not unusual for a young infant. If hiccups happen during a feeding and don’t stop within that 5- to 10-minute window, resuming the feeding for a few minutes typically does the trick.

Unlike adult hiccups, which can feel uncomfortable or annoying, newborn hiccups don’t seem to bother most babies. You may notice your baby hiccuping contentedly or even falling asleep mid-episode. If your baby seems unbothered, there’s no need to intervene at all.

Why Newborns Hiccup So Much

Newborns hiccup frequently because their diaphragm, the dome-shaped muscle that drives breathing, is still maturing. Any minor irritation or stretching of that muscle can trigger a spasm, which produces the familiar “hic.” Feeding is the most common trigger: swallowing air, eating too quickly, or having a very full stomach can all set off a round of hiccups.

There’s also a developmental purpose behind all that hiccuping. A 2019 study from University College London found that each hiccup sends a distinct pattern of brainwaves through the newborn’s brain. The diaphragm contraction produces two large waves in the cortex, followed by a third wave that resembles the brain’s response to sound. Researchers believe this helps the baby’s brain connect the “hic” sound with the physical sensation of the diaphragm contracting, essentially building an internal map of how the breathing muscles work. The circuits that process body sensations aren’t fully developed at birth, so hiccups may play a role in teaching the brain to eventually control breathing voluntarily.

This process actually begins before birth. Babies start hiccuping in the womb during the second trimester, inhaling amniotic fluid into their developing lungs and causing the diaphragm to contract. These fetal hiccups are considered a healthy sign that the respiratory system, brain, and spinal cord are developing on schedule.

When Hiccups Become Less Frequent

Hiccups are most frequent during the newborn period and the first few months of life, then gradually taper off as the diaphragm and nervous system mature. Most babies hiccup noticeably less often by around 6 to 12 months of age. They don’t disappear entirely (adults hiccup too, of course), but the multiple-times-a-day pattern that’s so common in newborns fades as the body’s sensory circuits finish developing and the digestive system becomes more efficient at handling feedings.

How to Help During a Hiccup Episode

The simplest approach is to wait it out. Most episodes stop within minutes without any help. If hiccups start during a feeding, you have a few practical options:

  • Pause and burp. Stop the feeding, shift your baby to an upright position, and try to get a burp out. This can release trapped air that’s irritating the diaphragm.
  • Help your baby relax. Gentle rocking or a change of position can calm the diaphragm spasm.
  • Resume feeding briefly. If the hiccups don’t resolve in 5 to 10 minutes, offering the breast or bottle again for a few minutes often stops them.

Prevention works better than any remedy. Feed your baby when they’re calm and before they get extremely hungry. A frantic, crying baby swallows more air and feeds more aggressively, both of which make hiccups more likely. If you’re bottle feeding, check that the nipple flow isn’t too fast, which can cause gulping and excess air intake. Keeping feedings smaller and more frequent also reduces stomach distension, another common trigger.

What Not to Do

Many of the hiccup “cures” that work for adults are unsafe for newborns. Never try to startle your baby, cover their mouth or nose, press on their eyeballs, or give them water or other liquids to “shock” the hiccups away. These old remedies carry real risks for infants, including choking and breathing problems. Gripe water and similar over-the-counter products are also not recommended for newborns without a pediatrician’s guidance. The safest strategy remains patience: let the hiccups run their course or use the gentle feeding adjustments described above.

Signs That Hiccups Need Attention

Ordinary newborn hiccups don’t require medical evaluation. However, hiccups that last more than 30 to 60 minutes, happen with unusual frequency throughout the day, or are paired with spitting up, arching of the back, or visible distress during feedings could point to gastroesophageal reflux. In rare cases, very persistent hiccups may signal a neurological issue. If hiccup episodes are regularly interfering with feeding or sleep, or if your baby seems genuinely uncomfortable during them, it’s worth bringing up at your next pediatric visit.
