Color of Baby Poop

The color of the stool depends a lot on what your baby is eating. In the first few days after birth, the baby’s bowels are sterile. But as some days pass by, a wide range of bacteria tend to grow in the bowel. And poop too!

So, the poop of a baby exclusively on breast milk would be different than a formula-fed tot. Also, the breastfed baby would also have a changing color of poop. Depending on what mummy eats!

Poop Consistency

The consistency of baby poop is also variable. And yup, the dietary factors are in play here too! So, the poop can be mushy and soft, filling the whole diaper. Or there can be small pellets. Or even a single hard stool.

The odor of Baby Poop

The odor of the poop tells how long the poop was in the baby’s gut. The longer the poop stays inside, the more the bacteria and hence foul smell.

In general, babies on breast milk tend to have odorless poops. And those on formula feeds have a slight odor. This definitely changes as solid food is added to the baby’s diet.

Babies’ Poop Smells Like Vinegar?

With the basics covered, we move on to the smelly problem; that is, why my baby’s poop smells like vinegar?

So, one day you decided to change your babies’ diaper. You noticed a strange acidic odor, like vinegar or sour cream from the diaper! And yup, apart from that horrible smell putting you off, you immediately start wondering if your baby is okay?

What Causes Poop to Smell Like Vinegar?

Baby poop normally does not smell like vinegar or sour cream. The acidic odor may indicate that your baby is having a hard time digesting their food.

It can also point to a bug in the tummy or some other tummy trouble. Some of which are given below:

Malabsorption of Food?

When the baby’s tummy is not able to properly absorb nutrients from the food, the resultant product is that babies’ poop smells like vinegar. Or gives off a sour, acidic smell.

Malabsorption is a problem that needs prompt care. Because not only does the baby’s poop smell like vinegar. The baby often has diarrhea and weight loss. With stunted growth!

Lactose Intolerance and Vinegar Poop!

One of the reasons babies’ poop smells like vinegar is that the baby’s tummy is sensitive to lactose present in the milk. Or other dairy products that you feed them.

In case you are breastfeeding your baby, lactose may enter the milk from lactose-containing products (mostly dairy) that you are consuming.

Keep an eye out for lactose intolerance as it presents with other symptoms too, such as bloating, baby passing too much gas, and even diarrhea or loose stools.
