In cases where a child's diarrhea is watery, it is generally considered that a viral infection could be the cause, such as rotavirus enteritis, which can produce yellow, watery stools. Exposure to cold leading to diarrhea can also result in watery stools; additionally, some intestinal bacterial infections may present with watery diarrhea. Therefore, it is important to analyze each specific situation. Using probiotics to regulate intestinal flora, and employing montmorillonite powder to protect the gastrointestinal mucosa can be considered. It is also advisable to visit a hospital to conduct routine stool tests, and if necessary, complete stool culture to guide further medication and treatment. (Medications should be used under the guidance of a doctor.)
