Breast Milk Diarrhea In Infants – What To Do And When To Seek Help

Breast milk is considered the best source of nutrition for infants, which is why healthcare professionals often recommend exclusive breastfeeding for the first six months. After that, solid foods can be gradually introduced. However, some exclusively breastfed babies may experience frequent loose stools, a condition commonly referred to as breast milk diarrhea. This type of diarrhea typically occurs in infants under six months old and often begins shortly after birth.

Babies with breast milk diarrhea usually pass stools that are foamy, watery, or contain small curds of milk. The stool may sometimes appear green and include clear mucus threads. It also tends to have a distinct sour smell. Bowel movements can range from 3 to 20 times a day. Despite this, affected infants generally remain active, feed well, and continue to gain weight normally. They often display the classic pattern of "eating, passing stool, and growing" without showing signs like poor weight gain, choking on milk, spitting up, abdominal bloating, pain, or excessive crying.

In most cases, breast milk diarrhea doesn't require medical treatment if the baby is otherwise healthy and shows no signs of illness. Parents should continue breastfeeding as usual, and the condition often improves once solid foods are introduced around the six-month mark. However, if the diarrhea starts to interfere with the infant's growth — such as causing poor weight gain, reduced urine output, or frequent diaper rash — it might help to give the baby lactase enzyme drops before breastfeeding. These drops assist in breaking down lactose in breast milk, potentially reducing digestive discomfort and diarrhea.

It's important to note that if your baby suddenly develops severe diarrhea with an increase in frequency, presence of blood or pus in the stool, fever, rash, persistent crying, vomiting, or decreased appetite, you should seek immediate medical attention. These symptoms could indicate an infection or another underlying condition that requires professional diagnosis and treatment.

Understanding the difference between normal breast milk diarrhea and more serious causes of diarrhea is key to ensuring your baby receives the right care at the right time. Always consult with a pediatrician if you're concerned about your infant's health or development.
