From Shandong,
Thank you to the doctor for answering my question quickly – how to treat and prevent it.

Doctor's answer:

Hello, considering your child's condition of poor digestion, using some Ji Nei Jin San and combining it with Mimi Ai treatment has been very helpful. For diarrhea, oral Er Xie Ting Granules can be used. Additionally, applying heat to the lower abdomen can also be beneficial.
