The World Health Organization and most pediatricians say: use tap water if it’s safe in your area. Boil it for a minute, let it cool, and you’re golden. Boiling kills the bad guys without stripping away the good minerals. That’s the sweet spot—safe and nutritious.
But here’s where it gets fun: if your tap water is sketchy (hello, Flint, Michigan), experts recommend using low-fluoride bottled water or nursery water—not distilled. Nursery water is basically tap water that’s been purified with a bit of fluoride added. It’s the lazy parent’s best friend. “But I’m already lazy at 2 AM—just tell me what to buy!” I hear you. So buy nursery water or a simple filter pitcher for your tap.
The one scenario where distilled water wins
Alright, let’s give distilled water its moment in the spotlight. If you’re traveling to a country where the water gives you the runs just brushing your teeth, use distilled. It’s sterile and predictable. Also, for the first few weeks of a newborn’s life—especially if they were premature—some doctors recommend distilled water to avoid any risk of infection. But that’s a temporary, medical judgment call, not a lifestyle choice.

Otherwise, distilled water is like wearing a suit to mow the lawn: it works, but it’s weird. Stick to what’s practical. Your baby doesn’t need water straight from a cloud; they need consistency and minerals. Fun fact: Distilled water can even taste flat and weird to adults, so imagine that for a baby’s developing palate. Not cool, distilled. Not cool.
