Why is my baby's stool loose and frothy?

Loose, frothy stools in infants may be caused by several factors, mainly including: 1. Physiological diarrhea: In breastfed infants, if the breast milk contains excessive lactose, it may lead to diarrhea-like, frothy stools. Parents should provide proper care, promptly change diapers, and clean the buttocks regularly. 2. Abdominal cold exposure: Failure to keep the infant's abdomen warm enough may cause excessive gastrointestinal motility, leading to diarrhea and frothy stools. Parents may apply a warm towel compress locally, making sure the temperature is appropriate. 3. Lactose intolerance: Some infants may lack lactase, an enzyme necessary for digesting lactose, which may result in frothy loose stools and bloating. Parents may feed the infant with lactose-free formula under medical guidance. 4. Indigestion: An infant's gastrointestinal system is not fully developed, and improper feeding or eating too quickly may result in indigestion with frothy stools. Parents may use pro-digestive medications as instructed by a physician and ensure appropriate feeding amounts. Parents should closely monitor the infant's symptoms and seek timely medical attention if symptoms persist or worsen.
