Baby Poop Smells Acidic: Causes, Treatment, And Prevention


Having a baby is one of the most exciting experiences for parents. However, taking care of a newborn baby can also be challenging, especially when it comes to their poop. It is normal for babies to produce different types of poop, but what if you notice that your baby’s poop smells acidic? In this article, we will discuss the causes, treatment, and prevention of acidic-smelling baby poop.

What is Acidic-Smelling Baby Poop?

Acidic-smelling baby poop is when your baby’s stool has a sour or acidic odor. It is often associated with green or yellowish color and a loose or watery consistency. Some parents might also notice that their baby’s skin around the diaper area is red or irritated.

Causes of Acidic-Smelling Baby Poop

1. Formula intolerance: If your baby is formula-fed, they may have an intolerance to the type of formula they are consuming. This can cause digestive issues, including acidic-smelling poop. 2. Breast milk imbalance: Breastfed babies can have acidic-smelling poop if there is an imbalance in their mother’s diet. Consuming acidic foods or drinks can affect the pH balance of breast milk, resulting in acidic-smelling poop. 3. Teething: Teething can cause digestive issues in babies, including acidic-smelling poop. This is because teething can cause excess saliva production, which can affect the pH balance in the digestive system. 4. Viral or bacterial infection: In some cases, acidic-smelling poop can be a sign of a viral or bacterial infection. This can cause other symptoms, such as fever, vomiting, and diarrhea.

Treatment for Acidic-Smelling Baby Poop

1. Formula changes: If your baby is formula-fed and has acidic-smelling poop, switching to a different type of formula may help. Consult with your pediatrician before making any changes. 2. Dietary changes: If your baby is breastfed, you can try making changes to your diet to balance the pH levels in your breast milk. Avoid consuming acidic foods or drinks, such as citrus fruits or coffee. 3. Teething remedies: If your baby is teething, you can provide teething toys or a cold washcloth to help soothe their gums. This can help reduce excess saliva production and improve digestion. 4. Medication: If your baby has a viral or bacterial infection, your pediatrician may prescribe medication to help treat the infection and alleviate symptoms.

Prevention of Acidic-Smelling Baby Poop

1. Proper hygiene: Keeping your baby’s diaper area clean and dry can help prevent irritation and infection, which can cause acidic-smelling poop. 2. Balanced diet: If you are breastfeeding, maintaining a balanced diet can help prevent imbalances in breast milk pH levels. 3. Regular check-ups: Regular check-ups with your pediatrician can help identify and treat any digestive issues before they become severe.


Acidic-smelling baby poop can be a sign of various digestive issues, from formula intolerance to viral or bacterial infections. If you notice that your baby’s poop smells acidic, it is essential to consult with your pediatrician to identify the underlying cause and provide proper treatment. By maintaining proper hygiene, a balanced diet, and regular check-ups, you can help prevent acidic-smelling baby poop and ensure your baby’s overall health and well-being.
