Inside Mother’s Tummy: Do Babies Fart In The Womb?

Infants are fascinating, and people often ask questions about their development and behavior, even before they’re born. One question that people often ask is whether they pass gas before they’re born. This topic explores how unborn infants’ digestive systems work and whether they can fart in the womb. Understanding what happens inside a mother’s tummy can help us appreciate prenatal life’s miracles. Fetuses display behaviors that hint at their future personalities and their ability to adapt, including their ability to taste the flavors of their mother’s diet and their responsiveness to external stimuli. Delving into these aspects of fetal development provides us with a deeper appreciation for the wonders of life before birth.

Can Babies Pass Gas In the Womb?

Pregnant women know what their unborn infant can perform while still unborn. From kicking to eating everything you eat to just floating around, you would be surprised by how much our precious ones are capable inside before they are even born, which is an amazing thing to learn. So, just imagine what else is there to come once you let them out of this world, right? No wonder, they bring so much joy to every family. 

Some parents believe their infant farts in the mom’s belly. Some mothers swear by this because they feel bubbly sensations and may wonder if their baby is passing gas. We know they do it frequently once born, but can they do it while still inside their mommy’s tummy?

Do Babies Fart In The Womb?

If you’re wondering, our answer to your question: Do babies fart in the womb? is no. A fetus does not ingest air and pass gas while still inside. Pregnant women can usually feel all bubbly and fluttery movements inside, but it is often just a woman’s stomach gas, or it’s her amniotic fluid splashing and sloshing inside her tummy.

Our precious little ones don’t have a particularly loud digestive tract like adults. It saves all its action for when an infant is born and takes their first breath. One thing that happens is that they produce their first stool called meconium. 

Most infants hold it in their meconium and release it after birth. But about 13 percent of fetuses may let a fetus bite it out. Unfortunately, there is a possibility that they swallow it, and it’s a rare case, but it is hazardous too. It’s called meconium aspiration syndrome. Swallowing their meconium could block an infant’s airways and lead to fetal distress. 

When fetuses poop inside a mom’s tummy, it’s usually always an emergency case, and that fetus needs to get out of mommy’s tummy immediately to avoid more complications. 

When your fetus has its first bowel movement, you may notice the stool looks different. There are no air pockets in the tummy as well, so your infant does not fart. Once your newborn is outside, it passes some fart and shows everyone what a tooter it is.

So What Are Those Bubbles In The Womb?

The bubbles you feel in your tummy are due to your baby and the amniotic fluid moving, along with your digestive tract reacting to your growing belly. It’s cramped inside, and those flutters are simply pressure adjustments in the shrinking space.

While it may seem like the fetal passing of gas, these sensations are caused by the movement within the amniotic fluid and the activity of your digestive system. Fetuses don’t produce gas in the womb; gas production begins after birth. So, soon-to-be parents, prepare for your newborn’s gas once they arrive!

Unique Things Babies Do In The Womb

Now that we’ve answered that question, we should talk about some unique things a fetus does while inside the tummy. Because while they can’t fart in the tummy, they do other fun stuff. You might just be surprised by all the activities a fetus can do to keep himself busy while he is cooking nicely inside the tummy for nine months. It’s a bit of a long wait, after all. 

They Love To Float Inside You

Infants naturally float from the earliest stages of development in the womb. During the initial weeks, they move freely before evolving into an embryo. This innate ability to float explains the feasibility of water births and why teaching infants to swim is often easier—they maintain a connection to their early aquatic experience.

Around six weeks, a fetus develops a heartbeat, which can be detected via ultrasound or Doppler. However, before this milestone, it primarily floats and resides in the womb.

They Can Hear You

Fetuses can hear sounds both inside and outside the womb, including their mother’s voice, which they can recognize at birth. Expecting mothers should avoid loud noises, as they can harm the fetus’s hearing.

Instead, it’s recommended to play gentle lullabies and classical music, as fetuses begin hearing these sounds during the second trimester and may respond with movements during the third trimester.

Playing music aids fetal brain development and offers a relaxing bonding experience for the mother and fetus.

They Can See Light

Fetuses can detect light outside the womb, especially bright light, in the final trimester. They can open their eyes when awake and even blink. Experimenting with a flashlight directed at the belly may elicit fetal movements in response to the light, stimulating their development.

Recent research indicates that spending time in the sun during pregnancy allows some sunlight to reach the fetus through the mother’s skin. This exposure to sunlight can aid in the development of the fetus’s eyesight and may prevent eye problems after birth.

They Drink And Roll Around And Pee

Bear Grylls would be proud. In the first 25 weeks, infants will pee into their amniotic sac. This pee combines with the amniotic fluid, and infants then drink that mixture. Who knew that being an unborn infant was like this? Sounds super gross, right? But remember, you were once a fetus inside the tummy, too, so you have done that as well. 


They Taste Food

Infants begin developing taste buds around 11 weeks in utero and can start tasting what their mother eats through the umbilical cord. Their taste preferences may be influenced by the mother’s diet during pregnancy. For example, if a mother consumes sweet or cold items, she might feel the fetus move more actively, similar to a sugar rush.

After birth, the flavors of the mother’s diet can also be present in breast milk, influencing the baby’s taste experiences. Additionally, breastfeeding benefits the fetus by promoting healthy gut bacteria. Therefore, mothers need to maintain a healthy diet during pregnancy and breastfeeding, as this can positively affect the baby’s eating habits and health.

They Can Feel Emotional Events From The Mom

Pregnant women’s emotional health is essential during and after pregnancy. She shares her emotional being with her baby in utero. 

Any positive feelings a mom feels, the infant inside the tummy also feels it. So it’s helpful for her and for the infant to feel cared for and loved and to feel relaxed and stress-free as the pregnancy progresses. 

If a mom experiences any trauma during pregnancy, it may affect the baby. The stress hormones released into the bloodstream are partaken as well by the baby. The baby may develop PTSD later on in their lives, even if they don’t experience any traumatic events themselves. Trauma may make it harder to have a successful delivery. If a mom has a traumatic event, it could lead to more severe cases such as miscarriage or premature birth.

A mother’s emotional state and social support during pregnancy can significantly affect her baby’s health and happiness. Reduced maternal stress, due to strong social connections and positive feelings, may lead to healthier and happier newborns.

Pregnant women benefit from having a supportive social circle, including family, friends, and support groups, to share experiences and manage the changes and challenges of pregnancy.

They May Be Able To Cry Inside You

A fetus can cry while in the tummy. It’s not loud, but the fetus can still quiver, be startled, gasp, and do everything else you associate with crying. It signals an important milestone in their development in utero because to cry means the development of systems in their tiny body is synchronizing and coordinating properly. This is a fascinating piece of information often highlighted in sonogram facts.

Even outside the tummy, it’s very typical for babies to cry. It’s their most primal way of expressing themselves and communicating. 


In conclusion, the world inside a mother’s womb is a fascinating one, filled with a multitude of activities and developments that occur during the gestational period. We’ve discovered that fetuses are far from passive occupants in the womb; they actively engage in a wide range of intriguing processes.

Contrary to some misconceptions, fetuses do not pass gas while inside the womb. However, they embark on a remarkable journey of growth and sensory experiences. They can taste the food their mother eats through the amniotic fluid, respond to external stimuli, and even exhibit emotions in their unique way. Hearing sounds from the external world and reacting to light sources are just some examples of their sensory perceptions.

As the pregnancy progresses, fetuses continue to develop, and they eventually start producing urine, contributing to the amniotic fluid that surrounds them. It’s truly remarkable to think about all these captivating activities occurring within a pregnant body, highlighting the incredible journey of fetal development before they enter the world.

Frequently Asked Questions (FAQs):

Where Does A Baby’s Poop Go And Do They Release Gas?

It’s sporadic for a fetus to poop while still inside the tummy. They usually get to hold it in until they are born. During the rare case that they poop while even in utero, the baby’s meconium will stay within the amniotic sac, and most likely, the fetus will swallow it. It could lead to meconium aspiration and become an emergency case where the infant needs to be delivered immediately to keep him away from more danger.

How Would You Know If Your Baby Is Hiccupping Inside You? 

Expectant parents often wonder about the experiences and activities of their unborn child, and one intriguing question that arises is whether fetuses can experience hiccups before they are born. Detecting fetal hiccups is an interesting aspect of prenatal life. While we cannot directly observe what’s happening inside, there are subtle signs that may indicate when your baby is experiencing hiccups even before their arrival into the world.

One of the signs to look out for is a slight, constant twitching or pulsing sensation in a rhythmic pattern in the abdominal area. This sensation is often described by expectant mothers as repetitive, almost like a gentle, rhythmic tapping from the inside. It is different from the usual kicks, stretches, and movements that are common in pregnancy. Identifying this distinct pattern of movement can lead parents to believe that their little one is experiencing hiccups, providing a unique connection between the parents and their unborn child.

Can Infants Smell Food Inside You? 

All of the baby’s senses are continuously developing in utero, especially during the final month of pregnancy. This includes his sense of smell. There’s still little study on human babies being able to smell while inside the tummy, but all of them resulted in an affirming that babies can indeed smell the chemicals going through their body while floating inside their mom’s tummy. 

Does A Baby Get Bored Inside You? 

Inside the womb, a fetus is remarkably active. They can eat, pee, perform somersaults, kick and jab, listen to external sounds, and react to flashing lights. With so many activities, a fetus is unlikely to get bored while growing for nine months in the womb.

Can Fetuses Cry? How Can I Make My Baby Happy Inside Me?

They can cry while inside the womb. The fetuses also take to what the mom is feeling. A baby will feed off the emotions of his mom while inside the uterus. To keep the baby happy, the mommy needs to surround herself with positive people, experiences, and activities. These should make her feel taken care of, loved, and secure. 

Can Fetuses Sense Their Father? 

An unborn baby can hear the voices of those who are talking to them or their mom. If the mom and dad spend a lot of time talking to the infant regularly, the infant will learn to recognize their father’s voice while in the womb. 

Is A Very Active Fetus A Good Sign? 

Fetal activity is always a good sign. This means the baby is developing well and getting stronger each day. Activity and movement are preferred over silence and lethargy when monitoring a baby’s movements. 

Can My Baby Feel When I Touch My Belly? 

The baby can feel whatever the mom is feeling. They will know when you are stroking your belly and talking to them. It will give you a great sense of love and excitement to see them once they are born. Your baby will feel all of that too. 

Why Should You Talk To Your Unborn Baby? 

A baby can hear sounds and voices even while they are still inside the womb. Exposing him to audio-sensory stimuli can help strengthen their sense of hearing. It will also help them recognize your voice when they are born. 

it's never too soon to start showing affection to your little one, even if/when they fart.

Can A Fetus Hear Music Through Headphones? 

Similarly, music is also an excellent stimulus for the baby while they are cooking inside their mom’s oven. They can hear the music you are playing through the headphones if you place them on your stomach. 

Can You Hear A Baby Crying Inside You?

It is not possible to hear a baby crying in the womb. In the early stages of development, specifically during the first trimester, the baby’s digestive tract and lungs are not fully developed. Since crying is a process involving exhaling air and making vocal sounds, an unborn baby, whose lungs are filled with fluid and not air, cannot cry in the conventional sense. While many women might feel movements or hear sounds from the baby, these are not indicative of crying as experienced in the outside world.

How To Know If My Baby Is Pooping Inside Me?

Babies poop in the womb, known as passing meconium. Meconium is the first stool of babies, and it is composed of materials ingested during pregnancy, including mucus, bile, and waste products. Unborn babies start to develop a digestive system that includes the intestines and kidneys as the fetuses grow. However, most babies do not release meconium until after birth, though it can occur just before or during delivery, especially in cases of premature babies. Passing gas or fetal flatulence is not a phenomenon that occurs in the womb, as the baby’s system is not exposed to air but is filled with amniotic fluid.

What Activities Occupy Infants Inside You Daily?

During their time in the womb, babies are surprisingly active and engage in various activities throughout the day. These activities include:

  • Movement: Fetuses move around quite a bit, with activities ranging from gentle kicks and stretches to more pronounced rolling and somersaults.
  • Sucking and Swallowing: They practice sucking and swallowing, essential for their ability to feed after birth.
  • Breathing Movements: Although they don’t breathe air, they practice breathing movements that help develop their respiratory system.
  • Hearing: Fetuses can hear sounds from the outside world, including their mother’s voice, other voices, and environmental noises.
  • Reacting to Light: They may respond to external light sources by changing their position or movement.
  • Sleeping: Like newborns, fetuses spend a significant amount of time sleeping in the womb.
  • Practice Reflexes: They develop and practice reflexes like gripping, sucking their thumb, and responding to touch.

These activities are crucial for their growth and development before birth, helping them prepare for life outside the womb.

What Happens To Fetuses Inside Mothers When They Are Hungry?

When a mother experiences hunger, it primarily impacts the nutrient supply to the fetus via the placenta, which is crucial for delivering nutrients and oxygen from the mother. While the fetal body efficiently utilizes the nutrients it receives, and the body prioritizes its needs, prolonged nutritional deficiencies can potentially affect fetal development. It’s important to note that normal maternal hunger does not immediately harm the fetus, thanks to the body’s protective mechanisms for the fetus. Regular healthcare check-ups are essential to monitor fetal health and development and address any issues related to nutritional deficiencies, ensuring the well-being of both mother and fetus.

Does A Baby Like Being Touched Inside You?

Babies do respond to touch in the womb, and it’s a fascinating aspect of their development. When touched, they often react with movements, and some studies suggest that they can feel and respond to gentle stroking or pressure from the outside. However, it’s important to understand that these responses are primarily reflexive and instinctual, rather than indicating specific likes or dislikes as we understand them.

The sense of touch is one of the earliest sensory experiences for a developing fetus. It plays a crucial role in their neurological and physical development. Touch sensations can stimulate their developing nervous system and help them become familiar with different types of stimuli, preparing them for the sensory-rich world they will encounter after birth.
