Thanks for your query.
Your child is having diarrhea
which is mostly viral in nature and takes few days to settle.
You are doing good job,continue.
Continue with oral rehydration solution sip by sip after each loose stools,coconut water,curd.
Add zinc for 14 days.
Observe him for signs of dehydration
,decrease in urine output,increase thirst,dry tongue.sunken eyes.
In case you find any get him evaluated by pediatrician
for proper evaluation and management.
