Introduction
If your baby’s stool contains foam, it may be due to overfeeding or consumption of indigestible foods. In such cases, reduce the feeding volume and offer easily digestible foods. You may also administer probiotics to help regulate the gastrointestinal microbiota. However, if your baby has enteritis—accompanied by abdominal pain—prompt medical evaluation is essential; a routine stool examination should be performed at the hospital. Additionally, check whether your baby’s umbilical area has been exposed to cold.

Whether a baby’s stool is normal directly reflects the baby’s health status. For instance, green stools may indicate abdominal chilling; curdled milk particles (“milk curds”) in the stool often suggest indigestion. So, what causes foamy stools in babies? Below, we provide answers to this question.

What Causes Foamy Stools in Babies?

Foamy stools in babies may result from overfeeding or consuming foods that are difficult to digest. In such cases, reduce feeding volume and offer easily digestible foods. Probiotics that help regulate intestinal flora may also be administered. If the baby has enteritis accompanied by abdominal pain, prompt medical evaluation—including routine stool analysis—is essential. Additionally, maternal diet may influence the baby’s stool characteristics. Mothers should review their own dietary habits: excessively oily, cold, sweet, salty, or greasy foods can all contribute to foamy stools in breastfed infants. Therefore, mothers should avoid such foods. Also check whether the baby’s umbilical area or feet are chilled—especially during summer air conditioning use—since inadequate warmth in these areas may likewise trigger foamy stools. Because infants’ gastrointestinal systems are still immature, medications—particularly antibiotics—should be avoided unless absolutely necessary and always under physician guidance, as inappropriate drug use may adversely affect the baby’s health.

Knowledge Extension: How to Care for a Baby with Foamy Stools

1. Breastfeeding is strongly recommended; avoid introducing other foods. If the mother’s breast milk is unusually thin or watery, ensure thorough sterilization of bottles and nipples when supplementing with formula.

2. Once the baby shows improvement, gradually introduce semi-liquid foods. Foamy stools may occur following abdominal chilling, so maintaining adequate warmth—and offering extra fluids—is important.
