Hello and Welcome to 'Ask a Doctor' service.
I appreciate your concern. No need to worry about this as most of the diarrhea
are self limiting in pediatric age group, and no need to give any medicine for this even you have to stop all the medicines.
At the most you can try the "lyophilized Bacillus" powder form. This could help in natural course of disease, watch for the dehydration
keep the kid well hydrated.
Hope this information helps you. Have a nice day.
