No, this is not the correct way. Two cups means approx. 200 gms. Give him just straight from bag. If you want to add a little milk or water, its up to u. Let it be for 5 minutes and serve in a bowl that is placed on a raised platform (say around on a wooden stool of around 10-12 inches height). By doing this, he will not be putting stress on his toes (pasterns) and not loosing their strength/shape.
