Re: Humid, Hot Weather and Decreased Nursing
Nursing is enough to provide for all your child's fluid needs. No need for water, unless you want to use it on the outside, wiping her down with a cool damp cloth when she seems to be really hot.
If your baby is not nursing enough to stay hydrated, then expressed milk, formula, or oral rehydration solution (e.g. Pedialyte) would be your options, in that order of preference. Water in excessive amounts can throw off a baby's electrolyte balance, and that can make her sick. A sip or two isn't going to hurt, but you would never give a baby a bottle of water.
