Baby Poop Smells Like Vinegar – 5 Important Reasons and What to Do

Baby Poop Smells Like Vinegar – 5 Important Reasons and What to Do

As a new parent, it’s important to monitor your baby’s poop since it can change daily based on their health and diet. For instance, baby poop smells like vinegar can indicate whether or not your infant is getting enough to eat and drink and can also reveal the health of their digestive system.

Breastfed babies typically have poop with a sweet smell or no smell at all, while formula-fed babies have more solid and slightly unpleasant poop. As babies start eating solid food, their poop becomes thicker and more noticeable.

However, if your baby’s poop smells like vinegar, it could be a sign that they’re not digesting their food properly or have a disease like a cold or stomach virus. It could also be an adverse reaction to milk or food.

Some parents have even reported that their baby’s poop smells like vinegar when they’re teething. Monitoring your baby’s poop can provide important clues to their health and eating habits.

It’s important to note that this article is meant to provide information and not medical advice. If you have concerns about your baby’s poop, it’s best to consult with a healthcare provider.

Why Do I Need To Monitor My Baby’s Poop?

The appearance and smell of your baby’s poop can provide valuable insights into their digestive health. Size, consistency, frequency, and odor can give clues about your baby’s gut health.

However, it’s important to note that there is no one-size-fits-all standard for what constitutes healthy baby poop. While one baby may have small, firm stools, another may have looser, watery stools. Ultimately, what’s most important is that your baby’s poop is consistent and predictable.

It’s also worth noting that while baby poop is universally recognized as being smelly, newborns typically produce almost odorless stools. As beneficial bacteria colonize your baby’s digestive system, you can expect the smell to become stronger and more noticeable. However, it’s rare for the odor to be intolerable.

That being said, there are instances where baby poop may have an unpleasant vinegar-like smell. This can be a sign of digestive issues or other health concerns, so it’s important to monitor your baby’s poop closely and consult with a pediatrician if you have any concerns. By staying vigilant and informed, you can help ensure that your baby stays healthy and happy.

Baby Poop Smells Like Vinegar, Why?

Let’s discuss the issue of stinky baby poop. Normally, the bowel movements of a newborn baby should not produce any odor or just a faint one. As the baby’s digestive system starts to develop, bacteria will begin to grow, and with it comes a distinct smell during bowel movements.

It is typical for your baby’s feces to have an unpleasant odor; there’s no need to worry unless it becomes overpowering or acidic, such as the scent of vinegar. In such cases, it’s essential to pay attention to what you and your baby are eating, especially if you’re nursing.

Your baby’s bowel movements can provide you with important information about their overall health and help you determine whether dietary changes are needed or if a pediatrician should be consulted for further advice.

Routine Causes

There are several various causes of the odor in your baby’s poop if it smells like vinegar.

1. Bad Gut Flora

The term “gut flora” simply refers to the bacteria that live inside our intestines. Babies are supposedly nearly sterile and bacterial-free when they are born. Most likely, we need the “good” bacteria that are already there. It is already known that babies born vaginally are exposed to their mother’s germs. 

According to research, newborns delivered by C-section may have their “good” bacteria disturbed, which would cause their bodies to accumulate harmful germs more quickly. An early abundance of harmful germs may cause your baby’s excrement to smell strongly of vinegar.

2. Allergies Or Sensitivities To Food

You could experience mixed emotions when your kid achieves the exciting milestone of being ready to eat solid foods. 

Although learning about food allergies and sensitivities at this age is unpleasant, it’s a fantastic opportunity to help them develop their taste buds and learn what they prefer. As your infant experiments with new meals, start paying attention to their bowel movements.

It’s normal for their stools to change in texture, color, and odor. If anything smells worse than it should, it can be a sign that they are responding to anything they ate that their body is unable to process.

3. Intolerance Of Lactose

Your baby’s pungent poop may be caused by something that they are unable to digest, similar to food allergies and sensitivities. Lactose is a leading candidate for this. It can be problematic for a baby’s developing digestive system considering that adults can hardly digest it.

Many formulas contain dairy, so look at the list of ingredients before purchasing any to see if it could be the source of your baby’s poop’s vinegar-like smell.

4. Crohn’s  Disease

Crohn’s disease, also referred to as a chronic or long-term illness, affects the digestive tract and results in inflammation and ulcers. Babies might be difficult to diagnose, but it is still possible. Babies with this illness are unable to effectively absorb nutrients, and this improper absorption can result in excrement that smells bad.

5. Cystic Fibrosis

Mucus builds up in the lungs and digestive tract as a result of the deadly hereditary illness known as cystic fibrosis (CF). Similar to Crohn’s disease, this isn’t the first thing you’ll want to talk about when talking about your baby’s vinegar-smelling feces, but it can’t be completely ruled out. 

Greasy stools and intestinal obstructions are just two of the many symptoms your child may experience if they have CF. In addition to causing your child considerable discomfort and anguish, such issues can easily make their stool smell foul.

Other Possible Causes For Your Baby’s Sour-Smelling Poop

Intolerance to lactose Babies with sensitivities to lactose in milk or other dairy products may have abnormally sour feces. If you are breastfeeding, your baby may be sensitive to the dairy you ate and passed on to him through your breast milk or the milk you are feeding him.

Watch out for symptoms of gas, bloating, and diarrhea as they may potentially indicate lactose intolerance.

1. Malabsorption

Your baby’s excrement may have an acidic odor when the nutrients from food are not properly absorbed in the digestive system. A virus, parasite, infection, or specific conditions can all cause malabsorption. Additionally, diarrhea and weight loss may result.

2. Teething

There is no scientific evidence to support this, but some parents claim to have observed excrement that smelled like vinegar just before one of their child’s teeth came in.

3. Food Sensitivity

Some foods are harsh for your baby’s digestive system and are challenging for him or her to digest. Your baby’s excrement becomes thicker and has an acidic odor as a result, among other things. Nuts, soy, dairy products, and eggs are frequent offenders.

4. Food Allergies

Your kid may have experienced an intense reaction to anything he ate if his excrement smells bad, smells like mucus, or has blood or mucus in it. The reason for this is that some foods have the potential to irritate the lining of the digestive tract. Consult your doctor if you have a family history of food allergies.

5. Rotavirus

This extremely contagious virus can produce vomiting, loose, smelly, black feces that are also bloody or puss-filled, with a strong odor.

6. Crohn’s Illness

Poop caused by Crohn’s disease may be watery, loose, explosive, and particularly sour. There may be blood and mucus in the feces as well.

What To Look For If Your Baby’s Poop Smells Bad

It’s normal for your baby’s poop to occasionally have an unpleasant odor, especially when introducing new foods to their diet. However, a sudden and noticeable change in their stool, such as a foul smell, blood, mucus, or diarrhea, could be an indication of a medical problem that requires attention.

If you notice any changes in your baby’s poop, it’s essential to pay attention to their other symptoms of illness or discomfort. Take note of everything they’ve eaten in the past few days, especially new foods.

While one or two episodes of loose, unpleasant feces may not be a cause for concern, frequent occurrences throughout the day require medical attention. Make sure your baby is getting enough fluids as diarrhea can lead to dehydration.

In conclusion, monitoring your baby’s poop, along with their behavior and health, can provide valuable insight into their overall well-being. It’s always better to err on the side of caution and consult a pediatrician if you notice any significant changes.

Things To Watch Out For

It’s important to keep an eye out for any symptoms that could indicate a bigger issue requiring immediate attention, in addition to the vinegar-like smell in your baby’s feces.

If you suspect a more serious condition like CF may be causing the change in feces odor, your child likely underwent a newborn screening for it before leaving the hospital. If your baby tests positive, speak with the healthcare professional overseeing your child’s care to learn how to manage the condition.

Experts advise contacting your doctor or seeking immediate care if your baby exhibits any of the following symptoms:

  • Fever
  • Irritability
  • Vomiting
  • Abdominal discomfort
  • Abdominal distension
  • Ten or more bloody stools in 24 hours
  • Abdominal pain
  • Suspected dehydration (no urination in over 8 hours or dark urine)

If your baby is under three months old and has a fever, or if they are under one month old and have three or more watery stools, take them to the emergency room as soon as possible.

How To Manage Babies Whose Poop Smells Like Vinegar

If your baby’s excrement has a vinegary scent, don’t freak out. Give it a little while to settle down (but not too long), then experiment with adjusting your diet by avoiding dairy items, switching up his formula, or giving him probiotics to see if that helps. You need to call your pediatrician right away if your youngster encounters any of these.

Summary

As newborns grow and adapt to their surroundings, they undergo various physical changes, including adjustments in their intestines and bowel movements. This can result in poop that has a foul odor. In some cases, the smell can be similar to vinegar, which is more common than you might think.

However, before you panic, it’s important to consider the causes that have been mentioned and keep an eye out for other symptoms that may indicate a more serious issue. This will help you determine whether you can handle the situation on your own or if your child needs medical attention. Being vigilant and informed can help you ensure your baby’s health and well-being.
