Hi
Thanks for your query.
Diarrhea can be viral or bacterial in nature,
Antibiotic is given when it is bacterial infection
Most important is to maintain hydration.
Give oral rehydration solution sip by sip after each
loose stool,continue with zinc and prebiotic
Also give coconut water,curd,banana,boiled potato,rice porridge.
Watch for any signs of dehydration;
lethargy,decreased urine output,increased thirst.
I suggest you to get him examined by
pediatrician to rule out infection.he may need a stool examination.
Wishing your child good health.
God bless.
