Question
A four-month-old male infant developed diarrhea symptoms the night before yesterday, which continued for several days. Each bowel movement was small in quantity, accompanied by a slight swelling of the belly. After taking Lactobacillus casei and Bifidobacterium infantis powder for one day, the baby’s bowel movements increased in volume by noon today, with particles present and a feeling of belly swelling. Over the past few days, there has been a lack of appetite, with whatever is eaten resulting in diarrhea.
