Consequently, during the first few days of life, the infant no longer depends on the umbilical cord to carry nutrients from the mother to them. The infant must now eat and digest food reasonably autonomously.

The organs of a newborn baby are still figuring out how to work, and they need several probiotics for proper digestion which is another reason why newborn farts smell so bad.

In other words, some proteins, carbohydrates, and lipids included in your breast milk or their formula may be more challenging for your newborn to digest adequately.

Due to fast digestion during the first month, food typically slips through your newborn’s system without completely breaking down.

Gas can then become stuck in the bowels and make babies fart much more frequently.

Additionally, newborns lack the intestinal flora required for breast milk digestion. This is another reason why your newborn farts smell really bad.

In the digestive tract of adults, bacteria assemble to facilitate easier food digestion. And, since newborns have a clean gut, it will take some time for the bacteria to grow in their bodies.

Instead, newborns have pro-bacteria in their bodies, which can produce gas and cause your baby to fart frequently and smell bad.
