Diarrhea in babies after fever reduction is considered to be a gastrointestinal disorder caused by indigestion and also related to diarrhea caused by cold. You can give your baby some oral medications for treatment, such as mamethoxazole, montelukast, infant spleen-healthy powder, and pediatric anti-colic oral liquid. Massage your baby’s abdomen clockwise with your hand every day to promote gastrointestinal peristalsis and digestion, eat less cold, spicy and stimulating food, eat more easily digestible food to prevent aggravation, and pay attention to increasing and decreasing clothing to prevent the abdomen from getting cold.
