Newborn Smelly Farts: Causes, Prevention, And Treatment


Welcoming a newborn into your home is an exciting experience, but it can also be overwhelming, especially if you’re a first-time parent. One of the things that new parents may find surprising is the smell of their baby’s farts. Yes, you read that right – newborns can have smelly farts! In this article, we will explore the causes of smelly farts in newborns, how to prevent them, and what treatment options are available.

What Causes Newborn Smelly Farts?

Smelly farts in newborns are common and can be caused by a variety of factors. One of the main reasons is that newborns have an immature digestive system that is still developing. As a result, they may not be able to fully digest certain foods, which can lead to smelly farts. Additionally, newborns may swallow air while feeding, which can also contribute to smelly farts.

What Foods Can Cause Smelly Farts in Newborns?

Breastmilk or formula is the primary source of nutrition for newborns, and certain foods that mothers eat can contribute to smelly farts in their babies. Foods that are high in sulfur, such as broccoli, cauliflower, and eggs, can cause smelly farts. Dairy products and foods that are high in fat can also contribute to smelly farts in newborns.

How to Prevent Newborn Smelly Farts

Preventing smelly farts in newborns can be challenging, but there are a few things you can do to help reduce the odor. First, try to identify which foods may be causing the problem and eliminate them from your diet if you’re breastfeeding. If your baby is formula-fed, talk to your pediatrician about switching to a different type of formula. Additionally, make sure you’re burping your baby regularly during feedings to help reduce the amount of air they swallow.

Treatment Options for Newborn Smelly Farts

If your baby’s smelly farts are causing discomfort or other symptoms, such as bloating or diarrhea, there are a few treatment options available. One option is to try a probiotic supplement, which can help improve your baby’s digestive health. You can also try giving your baby small amounts of water to help flush out their system. If the problem persists, talk to your pediatrician about other treatment options.


Smelly farts in newborns are a common occurrence and are usually nothing to worry about. Understanding the causes of smelly farts in newborns and taking steps to prevent them can help reduce the odor and keep your baby comfortable. If you have concerns about your baby’s smelly farts or other digestive issues, talk to your pediatrician for guidance and advice.
