Since most of the country is sweltering with summer heat and temperatures well into the upper 90’s and even over 100 degrees, I guess I can understand parents’ concerns about giving their babies water. It seemed like a strange question to me when I first started hearing, “Dr. Sue, how much water does my baby need to drink every day?”  I know I am continuing to talk about staying hydrated during the heat wave, but we are really talking about those children and adults who are spending time outdoors, especially when involved in physical activity.

I have actually been telling parents with newborns that there is really no reason to take that sweet new baby outside for any length of time. I think it is too hot to enjoy being outside, and an infant doesn’t miss going to the playground like a 2 or 3 year old would.

But, when you have young children you have to get out (or go crazy inside everyday), so everyone just suffers through the heat. Remember to take your sunscreen and fluids and head out for an hour or two, in the morning or later afternoon if at all possible. These children need lots of water breaks, as do their parents and caregivers.

So, back to the water and baby question. Infants in the first 6 months are getting fed breast milk or formula which is made up of free water, so therefore a baby is staying hydrated by eating every  2 -3 hours. A baby doesn’t “need” water every day for any particular reason.

With that being said, it does not mean that your baby cannot have a bottle of water. This is especially true for a breast fed infant whose mother may have run out for an hour but is coming back to breast feed.  But what if the baby awakens or gets hungry 30 min or so prior to mother getting home.  This might be a good time to “stall” by giving the baby a bottle of water, rather than formula. In this case it is fine to use tap water (yes bottled water is not necessary, unless you have a well or something) in a bottle and see if the baby will even take it. Most babies don’t just gulp down 8 ounces of water!

If you are out in the heat with an infant, just remember to feed them every 2 – 3 hours and make sure they have nice drool in their mouths and wet diapers. If you are concerned about hydration take along a bottle of water for both you and your baby. You will probably need it more than your baby!

That’s your daily dose for today.  We’ll chat again tomorrow.
