Babies Poop Smells Like Vinegar: Why Does It Happen?

Hello, my beautiful parents! Welcome back to another blog post. I am so happy to have you here! Today we are talking about an oh glamours topic: Why your babies poop smells like vinegar. 

Yes, you read that correctly; this is a real thing! And that’s why I’m covering it in a blog post. So, you don’t freak out if this ever occurs. Don’t worry, I got you. 

So, sit back and relax, grab a snack if you wish. Maybe avoid the salt and vinegar chips tonight –you’ll thank me later. Let’s get into it, shall we!

Why Does Babies Poop Smells Like Vinegar?

If you know anything about poop, especially baby poop, you’ll see that it can vary on a day to day basis! 

This is mostly because your little one’s stomach is sensitive, and sometimes, they get tummy aches! It happens! 

But what if your baby’s poop smells like vinegar? If this is the first time this is happening, then I completely understand the anxiety. Poop is not supposed to smell like vinegar. I get it! 

And anything out of what we believe as new parents are enough to send someone crazy!

As new parents, we already understand that we are supposed to monitor your newborn’s poop as it can indicate whether or not they are getting enough to eat and drink. It again also shows us how their digestive tract is working.

Let’s take a look at a couple reasons why this vinegar smell can occur.

Reasons Behind the Vinegar Smell

Did you know that breastfed babies typically have a sweet-smelling poop, whereas bottle-fed babies have more solid poops that are a little stinky? 

I didn’t either, but this is what I found throughout my research as a new mom, so we’re going to roll with it. To me, poop smells like poop, and that’s the bottom line if you ask me!

So, if your baby’s poop smells like vinegar, it could be an indication that they are not digesting their food well enough! 

It could also mean that they are coming down with a cold or stomach bug, so keep this in mind!

Here are a couple more reasons that could explain the vinegar smell.

Allergies to Food

If you find that your little one’s poop has a foul vinegar smell, it could be an indication that your baby has an allergy to some type of food that they have eaten. 

There could be the presence of mucus and a little blood in the poop as well. If this is the case, then take your little one to the doctor and get an allergy test to narrow down what it could be.

Digestion Problems

Another reason why baby poop smells like vinegar is that they are improperly digesting their milk. 

If your little one is not absorbing the nutrients from their milk or formula, it will begin to go sour in their little tummies, which would then cause them to have stinky poops. This could be because they have a cold or flu, or it could be a medical reason. 

I suggest waiting a day or two to see if your baby’s poop is still smelling bad. If it hasn’t gone away, there is nothing wrong with taking them to your family doctor for a checkup to make sure they are okay.

They Are Teething

Teething can cause all different types of reactions in your little one, including rosy cheeks, crying, eating their toys, and of course, digestive problems!

Crohn’s Disease

There is also a chance that your baby may have Crohn’s disease. Now, before you begin to freak out, the chances of this being the case are not that high. 

Crohn’s disease occurs when the inside wall of the intestines is inflamed. It can prevent your baby from absorbing the nutrients, which will again turn into vinegar smelling poop. 

Suppose you are worried about your little one’s health. In that case, I also recommend taking them to see your family doctor as they can help you get to the bottom of why your little one may not be feeling well. 

There is nothing wrong with going in whenever you have concerns!

Cystic Fibrosis

Another more serious condition that could be causing your child to have vinegar smelling poops is the genetic conditions Cystic Fibrosis. 

Suppose your child has already been diagnosed with the disorder at birth. In that case, vinegar poop is a common symptom associated with the condition. 

Again, if your baby already suffers from this disorder, it is always best to check in with your doctor. Keep an eye on how they are feeling, and use your parent’s intuition! 

Trust me, it is stronger than you may think it is!

When You Should Really Begin to Worry About Vinegar Smelling Poop

Here are some red flag symptoms to keep in mind if your little one’s poop starts to smell like vinegar:

  • They have more than 6 bowel movements within 6 hours.
  • They are experiencing shortness of breath.
  • You cannot soothe them.
  • They are vomiting
  • There is blood mixed in with their poop.

Again, while vinegar smelling poops aren’t necessarily any cause for immediate concern, it is always better to be safe than sorry!

Final Thoughts

At the end of the day, babies go through an enormous amount of changes within the first year, and it is common for them to have changes in their poop as a result of it! 

Before panicking, consider the factors that I laid out above when determining if it is worth the need to go to the doctor. As a parent, you will know when your child is feeling well and under the weather. 

So, pay attention to how they react and respond to you and make your decision as you think best.

Thank you again for tuning in! Until next time parents –it’s been a blast!
