Why Babies Under 6 Months Shouldn't Drink Water

For new parents, hydration is often top of mind — especially during warmer months in Georgia. It’s natural to wonder whether your baby needs a little extra water between feedings. But here’s the surprising truth: babies under 6 months should not be given water, and doing so can actually be harmful to their health.

🧠 The Science Behind It: Tiny Kidneys, Big Risks

Infants have developing kidneys that aren’t equipped to process water the way older children or adults can. When a baby drinks water before their body is ready, it can dilute the sodium levels in their bloodstream. This condition, known as water intoxication, can lead to:

• Seizures

• Brain swelling

• Low body temperature

• Irritability or drowsiness

Even small amounts — just a few ounces — can disrupt the delicate balance their body relies on.

🍼 What Babies Really Need for Hydration

Breastmilk and infant formula are perfectly designed to meet all of a baby’s nutritional and hydration needs. These fluids contain the right balance of water, electrolytes, and nutrients to support healthy development. No additional water is necessary — even in hot climates.

If your baby seems thirsty or fussy, offering more frequent feedings is the safest and most effective way to keep them hydrated.

👵 But Grandma Said It Was Fine…

It’s common for well-meaning family members to suggest giving water to soothe or hydrate a baby. While this advice may have been passed down through generations, pediatric guidelines have evolved with research and evidence. Today, experts agree: wait until your baby is at least 6 months old before introducing water, and even then, only in small amounts alongside solid foods.
