Can a 19-month-old baby take lactobacillus and what should be done?

Patient's question:

19-month-old baby, vomiting and diarrhea, mixed with undigested food

Doctor's answer:

Consider whether the child with diarrhea has indigestion. If the routine stool test is normal, consider that it may be due to a cold or indigestion. In such cases, it is recommended to take Mamikai, Smecta, and Cardu Granules for treatment. Additionally, use Baobao Yitie Ling patch on the navel for symptomatic treatment. If dehydration occurs, further treatment with oral rehydration solution or intravenous infusion may be necessary.
