The color and smell of the little one’s poop help reflect the health of a baby. Poop checking is a very essential step for parents because the poop color will suggest whether the baby’s health is normal or not.
Parents’ job is very challenging right after the addition of a new member in the family. According to pediatric experts, the digestive system of young children is still very immature, incapable to absorb nutrients entirely.
Baby poop alters almost every day based on the little one’s condition of health and food consumption. Therefore, the state of infant stools with a mild sour smell is a normal sign that parents can bear at home without being too anxious.
An infant’s poop varies in color and texture during their first few days, weeks, and months of life.
Why Do Babies Poop Smells Sour?
If your baby’s poop is smelling sour, it could be caused by lactose intolerance, malabsorption, teething, Crohn’s disease, food allergies, rotaviruses, or cystic fibrosis.
Your baby’s poop smell may be sour or acidic if he is not digesting his solid foods properly or whenever bacteria have entered your infant’s gut, that’s why smells begin to form. Due to these bacteria, babies start emitting odor when they poop.
It is usually normal so you don’t need to worry when your baby’s poop has a smell. But it is important to pay more attention if the smell is too pungent or acidic. Sometimes the poop smells like vinegar.

Types of Baby Poop Smells
There are a few types of baby poop smells that occur commonly.
1. Newborn’s First Poop (Meconium)
A newborn’s first bowel movement is meconium. In the first 24 hours of life, almost every newborn passes a meconium stool. This black-green substance is extremely sticky, more like tar than a turd.
You may find it difficult to wipe it clean at all. According to Robin Williams, meconium looks like a cross between Velcro and toxic waste. However, it is completely normal.
Newborns have nearly no gut bacteria that causes smelly poop. Meconium begins changing color and texture after two to four days, indicating that it is now a transitional stool.
You can expect a lighter color (think army green) and a less sticky texture. Your child’s poop shows that her/his intestinal tract is working, and she/he is digesting breast milk or formula milk.
Many babies struggle to pass meconium even after birth due to blockages. Your doctor will look for problems if your baby doesn’t have its first bowel movement within 24 hours.
Some of these include a poorly developed anus, intestinal blockages, and meconium plugs (stuck stools).
2. BreastFed Baby’s Poop Smell
It is normal for breastfed babies to have loose poop that is sometimes grainy or seedy. “Seeds” are undigested milk fats, which is normal.
Breastfed babies usually have light-to-medium brown, green, or yellow poop. It is common for newborns to pass whitish, yellow, or pale seeds in their poop.
Breastfed babies’ poop smells quite mild but for babies who have breast milk and formula, the smell may be more strong.
There is no threat to your baby when he/she has a sweet-smelling poop. The sugar that your body produces during the process is called stercobilin, which is responsible for the sweet smell during the feeding of your baby.
However, if the smell of your baby’s poop is very strong and sour, it may be due to some other reason like lactose intolerance. Poop may smell stronger and more unpleasant when a baby shifts to solids.
3. Formula-Fed Baby’s Poop Smell
Formula-fed poop is different than breastfeeding poop. Formula-fed infants have more solid poop in comparison to those who are breastfed.
They smell a bit. This is because Formula milk has larger particles than breast milk, so it takes longer to process. The poop stays longer in the gut and passes more slowly.
These are typically browner in color and have a denser texture – they may have a yellow-brown, tan-brown, or greenish-brown shade. Many people compare it to peanut butter.
Additionally, formula-fed babies pass fewer bowel movements, sometimes only every two to three days, but they’re significantly larger.
Your baby’s health is very dependent on the food they consume.
5 Different Smells and What They Might Mean
1. Babies poop Smells Like Rotten Eggs

How often should baby poop?
The pooping patterns of babies differ widely. Some poop after every meal, while others only do so once or twice a week. You should make sure that your baby poop comes out reasonably soft.
It is normal for breastfed newborns to poop after every feeding (roughly 6 to 10 times a day), but after three to six weeks, they usually slow down and do not have bowel movements as frequently.
A breastfed baby may only have one bowel movement each week. It works in this way because breast milk passes without leaving much solid waste.
Formula-fed babies usually poop three to four times daily, but some go as long as three or four days without doing so.
You need not worry if your baby’s pooping pattern stays reasonably consistent and he behaves normally.
