Based on your description, your baby’s diarrhea may be caused by indigestion. It is recommended to use traditional Chinese medicine ‘Xingpi Yang’er Granules’ for adjustment, and to provide easy-to-digest and absorbable food, maintain a regular lifestyle, and avoid any potential adverse stimuli. Additionally, if your baby’s diarrhea does not improve, it is advisable to take your baby to the hospital for a check-up to determine the cause and receive appropriate treatment.
