My baby always liked the cereal mixed with breastmilk or fruit juice more than when I mixed it with water.I also would mix the stage one fruits(they are so runny and thin) with the rice cereal and my little boy loved it! He also has always liked plain water to drink, I dont think it will hurt them, the doctors say we have enough water in our breastmilk that is enough for them too.But if you mix it with food, it is fine too.
