Newborns are fascinating creatures, with their delicate features and seemingly endless array of quirks. Among these, hiccups are a common phenomenon that often puzzles and sometimes worries new parents. Understanding why newborns hiccup so much can help alleviate concerns and provide insight into the normal physiological processes of a baby’s early development. In this article, we will delve into the reasons behind newborn hiccups, when to be concerned, and how to manage them effectively.
What Causes Hiccups in Newborns?
Hiccups in newborns, much like in adults, are caused by the involuntary contraction of the diaphragm—a dome-shaped muscle that separates the chest cavity from the abdomen. When the diaphragm contracts suddenly, it causes a quick intake of breath that is immediately stopped by the closure of the vocal cords, producing the characteristic “hic” sound.
Immature Diaphragm Reflexes
Newborns have underdeveloped nervous systems, which means their diaphragm is more prone to sudden contractions. This immaturity is a primary reason why hiccups are more frequent in newborns compared to older children and adults. As the baby’s nervous system matures, the frequency of hiccups usually decreases.
Feeding Triggers
Hiccups can often be triggered by feeding. Newborns have small stomachs, and overfeeding can cause the stomach to stretch, leading to irritation of the diaphragm. Additionally, swallowing air while feeding can also lead to hiccups. Whether breastfed or bottle-fed, babies can swallow air during feeding, which accumulates in the stomach and creates pressure that irritates the diaphragm.
Temperature Changes
Newborns are also sensitive to temperature changes. A sudden drop in temperature, such as when a baby is undressed or experiences a draft, can cause a reflex action in the diaphragm, resulting in hiccups.
Gastroesophageal Reflux (GER)
Another common cause of hiccups in newborns is gastroesophageal reflux (GER). This condition occurs when the contents of the stomach, including stomach acid, flow back into the esophagus. The acid can irritate the diaphragm, causing it to contract and produce hiccups. GER is particularly common in newborns due to the immaturity of their lower esophageal sphincter, the muscle that closes off the stomach from the esophagus.
Are Hiccups in Newborns Harmful?
Normal and Non-Threatening
For the most part, hiccups in newborns are entirely normal and non-threatening. They are a common part of early development and typically do not cause any discomfort to the baby. Unlike adults, babies are usually not bothered by hiccups and often continue feeding, sleeping, or playing without disruption.
Sign of Development
Hiccups may even be a sign of a healthy development. The rhythmic contractions of the diaphragm involved in hiccuping could play a role in strengthening the baby’s breathing muscles and preparing them for more efficient breathing as they grow.
When to Be Concerned
While hiccups are generally harmless, there are instances when they might indicate an underlying issue. If a baby experiences very frequent or prolonged bouts of hiccups, especially if they interfere with feeding or sleep, it might be a sign of GER or other digestive issues. In such cases, it is advisable to consult a pediatrician to rule out any potential problems.

How to Manage and Prevent Hiccups in Newborns
Feeding Techniques
One of the most effective ways to manage and prevent hiccups in newborns is by paying attention to feeding techniques. Ensuring that the baby is properly latched during breastfeeding or using a bottle designed to reduce air intake can minimize the amount of air swallowed during feeding.
Burping During and After Feeding
Burping the baby during and after feeding can help release any trapped air in the stomach, thereby reducing the likelihood of hiccups. It is recommended to burp the baby midway through feeding, especially if they are bottle-fed, and again at the end of the feeding session.
Keep the Baby Upright After Feeding
Keeping the baby in an upright position for about 20 to 30 minutes after feeding can help prevent the contents of the stomach from pushing against the diaphragm. This is particularly useful for babies who experience hiccups frequently due to GER.
Slow Down Feeding
If the baby is prone to hiccups, slowing down the feeding process can be beneficial. Smaller, more frequent feedings may be less likely to cause overdistension of the stomach, which can trigger hiccups.
Use of Pacifiers
Sometimes, giving the baby a pacifier can help stop hiccups. The sucking motion helps relax the diaphragm and may ease the hiccup reflex.
When to Seek Medical Advice
Persistent or Painful Hiccups
If the hiccups are persistent, last for more than a few minutes, or seem to cause the baby discomfort, it is important to seek medical advice. Although rare, persistent hiccups could be a sign of an underlying medical condition, such as GERD (Gastroesophageal Reflux Disease) or an infection.
Hiccups with Other Symptoms
If the hiccups are accompanied by other symptoms such as vomiting, irritability, or poor weight gain, it is essential to consult a healthcare provider. These could indicate more serious digestive issues that require medical attention.
The Role of Parental Reassurance
Normalizing Hiccups
It is important for parents to understand that hiccups are a normal part of a newborn’s life. In most cases, they are not a cause for concern and do not require any special treatment. Reassuring parents about the normalcy of hiccups can help alleviate unnecessary anxiety.
Monitoring for Patterns
Parents can also monitor for patterns in their baby’s hiccuping. For instance, if hiccups consistently occur after a specific activity, such as feeding, adjustments can be made to minimize triggers. Keeping a log of when and how often the baby hiccups can also be helpful in identifying any patterns or triggers.
Conclusion
Newborns hiccup frequently due to the immaturity of their diaphragm and nervous system, feeding-related factors, and sometimes because of gastroesophageal reflux. While hiccups in newborns are usually harmless and a sign of normal development, it is important for parents to understand when hiccups might be indicative of an underlying issue. By adopting appropriate feeding techniques and being aware of when to seek medical advice, parents can manage and reduce the frequency of their baby’s hiccups. Most importantly, understanding that hiccups are a natural part of a newborn’s early development can help parents feel more at ease, knowing that their baby is growing and developing as expected.
