Please always give information about nutrition. What are you feeding? Did you go out to eat. How many motions he passed during last 24 hrs? Anyway I start ORS first. Feed the child every now and then to avoid dehydration. It has zinc also. It is beneficial.Feed Banana2at least in next 6 hrs. Give NutrolinB syrup 1tsf twice a day. I am sure he will be alright. In case you feel , he is not improving, start Furoxone syrup 1tsf twica day. Light diet like khichri with curds. He will love it. No beverages. You can feed coconut water.
Next Steps
Follow hygiene. Wash hands and his toys . He may be putting toys in mouth
