Hi,I had gone through your query and understand your concern.
I see similar cases in my clinic.Like your grandson,most of the children suffer from acute watery
diarrhea due to rota virus.This type of diarrhea is self limiting and I often advise as follows:
>Breast feed frequenly
>Give oral rehydration solution(
ORS) according to age and weight.
>Zinc tablet 20mg once daily for 10 days
>
Paracetamol syrup if
fever present
and request parents to keep patience as this type of diarrhea may take 3 to days to cure.
If your grandson's stool is mixed with blood and /or mucus,then I would suggest of taking antibiotic after getting positive stool R/M/E report.
Hope this helps you.If you have additional questions ,please do not hesitate to write us.
Wish your grandson good health.
