What Causes Newborn Hiccups

If your newborn hiccups after nearly every feeding, take a deep breath. There is almost certainly nothing wrong. Newborn hiccups are one of the most common things new parents notice, and the cause is almost always mechanical and completely benign. Understanding what's actually happening inside that tiny body can make the whole experience a lot less stressful.

It all starts with the diaphragm, a large sheet of muscle that sits between the chest cavity and the abdominal cavity. Think of it as the floor of your lungs. Normally, it contracts and relaxes in a smooth, steady rhythm to help your baby breathe. But when something irritates or agitates it, the diaphragm spasms suddenly. That spasm triggers a sharp, involuntary intake of breath, and the vocal cords snap shut almost instantly in response. That abrupt closing is what produces the classic "hic!" sound you hear.

Feeding is the number one trigger for newborn hiccups, by a wide margin. When babies eat too fast, swallow too much, or gulp air along with their milk, the stomach fills up quickly and starts pressing against the diaphragm from below. That pressure is enough to set off a spasm. According to WebMD's guidance on baby hiccups, overfeeding and rapid feeding are consistently cited as the most common culprits in newborns.

A secondary trigger worth knowing about is gastroesophageal reflux, or GERD, which is when stomach acid flows backward up into the esophagus instead of staying in the stomach where it belongs. Since the esophagus passes directly through the diaphragm, that acid irritation can cause the muscle to spasm and kick off a round of hiccups. GERD-related hiccups usually come with other clues, like fussiness, spitting up, or back-arching after feeds.
