Thanks for your query,
your child is having diarrhea
which is usually viral in origin,
i advise you to maintain proper hydration, give him oral rehydration solution sip by sip after each loose stools.you can also give coconut water,buttermilk,curd ,mashed banana,mashed potato.also five him lactobaccilus sachet for 2 to 3 days.
In case diarrhea persist i advise you to take him to pediatrician
so that his stool gets tested and in case of any infection he will be treated accordingly.
Your child will be soon
