Due to the underdeveloped gastrointestinal function in children, there may be gastrointestinal dysfunction. The child’s belly may rumble and produce white, slimy mucus resembling snot. It is recommended to take Montmorillonite powder on an empty stomach to protect the intestinal mucosa, and to take probiotics to regulate the normal intestinal flora. No other medication is needed at this time, but oral hygiene should be maintained. If necessary, a stool routine examination can be conducted at the hospital to clarify the condition. Wishing the child good health.
