Why Babies Can’t Drink Water

By Brian Lemay 100 comments

There is a time in every person’s life when drinking water is deadly. Even as much as a few
ounces is enough to kill. The average healthy adult is
made up of 55 to 60% water. The average baby, on the other
hand, is roughly 75% water. And that difference is why
babies shouldn’t drink water before they’re at least six months old. Not from the tap or a well or a spring. Plain water is just plain off limits. You see, everyone’s kidneys have a limit to how much water they can handle. Break that limit, and the excess water will back up into your bloodstream, where it dilutes the salt,
or sodium, in your blood. Once your blood dips below 0.4
ounces of sodium per gallon, you’re at risk of a condition
called Hyponatremia. It happens when your cells
try to return sodium levels to normal by absorbing the extra water and swell up like a water
balloon in the process, causing complications like confusion, vomiting and muscle spasms. Hyponatremia is common in marathon runners who drink too much too fast during a race without also providing enough sodium to balance out their blood. And if you keep drinking,
that excess water will eventually reach
the cells in your brain. By this point, you have a dangerous case of water intoxication, which affects roughly 200,000 Americans each year. It occurs when your brain cells swell, which builds up pressure inside your skull that can lead to seizures, brain damage, and, in sever cases, death. But don’t worry, dying from
water intoxication is extremely hard for
a fully-grown human. An adult would have to
drink 2.5 to 5 gallons every few hours to reach that point. But for newborns, it’s a different story. Their kidneys are about
half the size of an adult’s, so they can’t hold much
water to begin with. And it takes just a few
ounces to cause problems. On top of that, their kidneys
aren’t developed enough yet to properly filter water, so any water that enters their body ends
up in the circulatory system, where it dilutes their blood and increases their
water content by 7 to 8%. But it’s not just drinking straight H2O that poses a threat. In fact, most cases of water
intoxication in infants don’t even involve a glass of water. A common mistake is when
people dilute baby formula too much by accident, or when parents dunk their infants up and
down in a swimming pool, and in the process the infant
gulps in too much water. It’s important that if your baby is showing signs of water intoxication that you take them to
the hospital immediately, where a doctor will likely
provide some form of fluids like intravenous saline solution to bring the infant’s
sodium levels up to normal.

The title is kind of misleading.. Babies should be drinking water in limited quantities of course not like an adult.. Also breastfeeding is the best to feed the baby for the first six months.. Most countries practice this instead of feeding water or formula….

Well here ( west Africa) the nurses instructed my niece to give her newborn a bit of water (a bottle cover's worth) a couple times a week. Baby is 2 months in a few days and looking perfectly healthy. Saying babies "can't" drink water is just wrong. They really mean babies shouldn't drink a lot of water.

We have gave my little cousin plenty of water before he was 6 moths and he is doing completely fine. I mean, we live in the Caribbean and that was such a delightful moment whenever he drank water, he used to get happy. Of course you’re not gonna choke them with a full cup of water but moderately it’s actually okay for them.

Babies can drink water but as a responsible mother, you should exclusively breastfeed your baby upto six months of age.

What nonsense. In hot climates, babies need water. My son wouldn't settle when he was born, and he was being given glucose water by the nursing staff – and lots of it! -in between feeds. He eventually settled on a pacifier, but that's beside the point. He was perfectly healthy and many babies drink lots of water safely. In hot climates it's a necessity.

This is ridiculous. The only reason it's not recommended is because it has no nutritional value and your baby needs to grow. Water is mixed with formula.

This is absolute BS, I have had 3 kids, and I gave them water, perhaps not from the 1st day,but certainly as newborns!

There was many a time my babies would be screaming the house down, and I would go through the whole kit and caboodle of hunger, dirty nappy, and so on, only to find that they were asking for water.

An ounce, or 2, and they would settle right back down straight away.

This wasn’t everyday, but it was retry clear that my babies were thirsty, and at the end of the day of the day, every other mom,at the time, gave their babies water, and I never heard of one becoming ill through drinking water.

And if a baby had died from drinking water it would have been known by most members of our community within a few days – no mobile phones getting in the way back then.

Nope cannot and will not accept this absolute crap, if a baby took 1ounce less of formula food at a feed, why couldn’t you replace this 1ounce of formula for drinking water.

After all, ain’t formula made up with water?
