What causes foam in a baby's stool?

Possible causes of foamy stool in infants include a cold abdomen, lactose intolerance, indigestion, and intestinal infections. A cold abdomen may lead to digestive issues, while lactose intolerance results from the inability to fully digest lactose. Indigestion may occur because the baby's gastrointestinal system has not yet fully developed. In addition, intestinal infections such as enteritis can also cause foamy stools. If symptoms persist or worsen, prompt medical attention is recommended.
