Newborn Sharting

Newborn Sharting


As a new parent, you might be surprised by the wide range of colors, textures, and smells that come from your newborn’s diapers. One particular phenomenon that may catch you off guard is newborn sharting. This article covers everything you need to know about sharting, including what it is, why it happens, and how it differs in breastfed and formula-fed babies.

Newborn Sharting Explained


What is Sharting?

Sharting is the combination of a small bowel movement (poop) and passing gas (fart) at the same time. It’s a common occurrence in newborns and can result in some messy diaper changes.

Why do newborns shart?

Newborn sharting is primarily due to the immaturity of a baby’s digestive tract. As your baby’s system develops, they might have explosive farts or sharting incidents in the early days of their life. This is totally normal and should lessen as they grow.

Differences between sharting and diarrhea

Although sharting can be messy, it’s important to differentiate it from diarrhea. Diarrhea in newborns is characterized by frequent, watery, and often foul-smelling poop, which can lead to dehydration. If you’re unsure whether your baby is experiencing sharting or diarrhea, consult your pediatrician.

Breastfed Babies and Sharting

Exclusively breastfed babies tend to have soft, seedy, and mustard-yellow-colored poop. It’s common for a breastfed baby to have frequent bowel movements and to shart, especially in the first few weeks of life.

How breastfeeding affects sharting

Breast milk is easily digestible, meaning that breastfed babies may pass stools more frequently than formula-fed babies. Consequently, they might experience more instances of sharting.

Formula Fed Babies and Sharting

Formula-fed babies usually have thicker and darker brown poop compared to breastfed babies. The frequency of bowel movements can vary, but they generally have fewer bowel movements than breastfed babies.

How formula feeding affects sharting

As formula takes longer to digest than breast milk, formula-fed babies may experience fewer instances of sharting. However, it is still normal for them to shart, especially during the early days.

Newborn Baby Poop: What’s Normal?


The color of your baby’s poop can range from yellow to green, brown, or even black (in the first few days after birth). As long as the color falls within this spectrum and isn’t accompanied by other concerning symptoms, it’s likely normal.


Baby poop can be runny, seedy, pasty, or slightly formed, depending on the baby’s age and diet. Sharting typically involves a small amount of poop with a loose consistency.


How often newborn poops can vary greatly. Some babies might have a bowel movement after every feeding, while others may only poop once every few days. As long as your baby is comfortable and their poop falls within the normal color and consistency range, their bowel movement frequency is likely normal.

Milk Protein Allergy and Sharting

Signs of a milk protein allergy

A milk protein allergy can cause gastrointestinal symptoms, such as frequent, watery, and mucousy stools, which can be mistaken for sharting. Other signs of a milk protein allergy include blood in the stool, irritability, skin rashes, and poor weight gain.

Managing a milk protein allergy

If you suspect your baby has a milk protein allergy, consult your pediatrician. They may recommend dietary changes, such as switching to a hypoallergenic formula or eliminating dairy from the breastfeeding mother’s diet

Other Reasons for Sharting in Newborn Babies

While the immaturity of a newborn’s digestive tract is the primary reason for sharting, there may be other contributing factors as well. Understanding these factors can help you better manage your baby’s bowel movements and ensure their health and comfort.

Gastrocolic Reflex

The gastrocolic reflex is the body’s natural response to food entering the stomach. This reflex triggers the colon to contract, often leading to bowel movements. In newborns, the gastrocolic reflex is more sensitive, resulting in more frequent bowel movements and sharting incidents, especially in the early days.

Food Sensitivities and Sharting

Some newborns may have sensitivities to certain foods consumed by their breastfeeding mothers. These sensitivities can cause increased gas and sharting in the baby. Common culprits include dairy, soy, and certain vegetables. If you suspect a food sensitivity, try eliminating the suspected food from your diet and observe if your baby’s sharting frequency decreases.

Introduction of New Foods

As your baby grows and begins to eat solid foods, their digestive system will need time to adapt to the new textures and ingredients. This adjustment period may lead to an increase in gas production and sharting as your baby’s digestive tract learns to process the new foods. Most pediatricians recommend introducing solids around six months of age. Introducing solids too early can cause digestive issues, including an increase in sharting incidents.


Dehydration can cause a newborn’s stool to become harder and more difficult to pass. In an attempt to pass the stool, the baby may experience increased gas and sharting. Ensuring your baby is well-hydrated by offering frequent feedings can help alleviate this issue.

Digestive Tract Development

A baby’s digestive tract is still developing during the first few months of life. This development process can result in gas production and sharting as the baby’s body learns to properly digest and absorb nutrients from breast milk or formula.

Anxiety and Stress

While it may seem surprising, newborns can be sensitive to the emotions of their caregivers. If a mother is experiencing stress or anxiety, this can affect her breast milk composition and lead to changes in the baby’s digestion, potentially causing increased sharting.

It is essential to monitor your newborn’s bowel movements and consult your pediatrician if you have concerns about their sharting frequency or if they exhibit other concerning symptoms. By understanding the various factors that can contribute to sharting in newborns, you can better support your baby’s digestive health and overall well-being.

Dealing with Dirty Diapers

Changing nappies

When changing a diaper after a sharting incident, use warm water and a gentle baby wipes to clean your baby’s bottom thoroughly. This helps prevent diaper rash and keeps your baby comfortable.

Preventing diaper rash

To prevent diaper rash, make sure your baby’s bottom is clean and dry before putting on a new diaper. You can also apply a diaper rash cream as a protective barrier.

Managing Newborn Baby Sharting

While sharting is a normal part of early infancy and typically does not require treatment, there are some steps you can take to help manage and alleviate sharting in your newborn baby.

Burping Your Baby

Ensuring that your baby is well-burped during and after feedings can help reduce gas buildup, which can contribute to sharting. Gently pat or rub your baby’s back to encourage the release of trapped air.

Tummy Time and Massage

Encouraging tummy time and gently massaging your baby’s belly in a clockwise motion can help relieve gas and reduce sharting. Be sure to consult your pediatrician before implementing any massage techniques, especially if your baby is showing signs of discomfort.

Adjusting Your Diet (For Breastfeeding Mothers)

If you’re breastfeeding and suspect that your baby’s sharting may be related to a food sensitivity, try eliminating common allergens such as dairy or soy from your diet. Observe if there is a decrease in sharting frequency after making dietary adjustments.

Switching Formula (For Formula-Fed Babies)

For formula-fed babies, sharting may be related to the type of formula they are consuming. Consult your pediatrician about trying a different formula, such as a hydrolyzed or lactose-free option, to see if it helps reduce sharting frequency.

Probiotic Supplements

Some studies suggest that probiotics may help support a healthy gut microbiome in newborns, potentially reducing gas and sharting. Consult your pediatrician before giving your baby any probiotic supplements.

Monitor Solid Food Introduction

As you introduce solid foods to your baby’s diet, start with small amounts and gradually increase the quantity as their digestive system adapts. Pay close attention to your baby’s reaction to new foods and consult your pediatrician if you suspect a particular food is causing increased sharting.

It is essential to remember that sharting is generally a normal part of early infancy and does not usually require treatment. However, if your baby’s sharting is accompanied by concerning symptoms or if you are worried about their digestive health, consult your pediatrician for guidance and support.

When to Consult a Pediatrician

Warning signs in baby’s stools

While sharting is a normal part of early infancy, there are certain warning signs in your baby’s stools that may indicate an underlying issue requiring medical attention. Recognizing these signs and knowing when to consult a pediatrician can ensure your baby receives the appropriate care.

Blood in the Stool

Finding blood in your baby’s stool can be alarming. Blood may appear as bright red streaks or dark, tarry stools. Blood in the stool can be a sign of a milk allergy, gastrointestinal infection, or other health issues. Consult your pediatrician if you notice blood in your baby’s diaper.

Mucus in the Stool

While a small amount of mucus in a baby’s stool can be normal, excessive mucus, especially if accompanied by other symptoms, may indicate an issue such as a milk protein allergy or an infection. Consult your pediatrician if you notice an increase in mucus in your baby’s stool.

Foul Smelling Poop

All babies have their own unique poop smell, but if your baby’s poop suddenly becomes extremely foul-smelling, it may indicate a problem such as a gastrointestinal infection or a food intolerance. Consult your pediatrician if you notice a significant change in the odor of your baby’s poop.

Persistent Diarrhea

Diarrhea in babies can lead to dehydration and other health complications. If your baby has persistent diarrhea, characterized by frequent, watery, and often foul-smelling stools, consult your pediatrician immediately.

Consistently Hard, Dry Stools

If your baby consistently passes hard, dry stools, they may be constipated. Prolonged constipation can cause discomfort and other complications. Consult your pediatrician for advice on how to alleviate your baby’s constipation.

Significant Changes in Stool Frequency

A sudden change in the frequency of your baby’s bowel movements, either more frequent or less frequent than usual, may indicate an issue with their digestion. While the frequency of bowel movements can vary greatly among babies, it is essential to consult your pediatrician if you notice a significant change in your baby’s bowel movement patterns.

Poor Weight Gain and Feeding Difficulties

If your baby is not gaining weight as expected or is experiencing difficulties with feeding, such as vomiting, excessive spit-up, or refusing to eat, these issues may be related to their digestive health. Consult your pediatrician to address these concerns.

Regular check-ups with your pediatrician are crucial in monitoring your baby’s growth and development. They can also help address any concerns you might have, including issues related to sharting and bowel movements. By keeping an eye on your baby’s stools and seeking medical advice when necessary, you can ensure your baby’s digestive health is on track.


Newborn sharting is a normal part of early infancy.
