Thank you for your query,
As he is having loose mpotions, try to maintain his hydration.
Hydration is maintained by giving sips of oral rehydration solutions like Pedialyte
, coconut water, and lemon water.
At home you can give curd and yogurt as they contain probiotic
which restores normal intestinal flora.
Consult your Pediatrician
for the asessment of your child hydration status and for treatment like probiotic and any antibiotic if neccessary.
For feeding try to give solid feeds and restrct milk as there may be indigestion
Hope I have answered ypour query.
