1. too much water will take the place of formula, babies need calorie.
2. too much water in an already small circulating system can overload the cns. not good.
3. why are you wanting to give water and not formula. the baby needs nutrition. breast milk or formula will give them plenty of water.
I agree. I never gave water until they were able to drink from a sippy cup.
