Can we give water to one month old baby?

So, you have a one month old baby and you’re wondering if it’s safe to give them water. After all, hydration is important, but is it really necessary for such a young infant? Let’s dive in and explore the answer.


As your little bundle of joy grows day by day, their dietary needs are going to change quite rapidly. It can be overwhelming trying to keep up with what they should or shouldn’t consume! While as adults we know that drinking enough liquids each day is essential for our overall wellness—can the same apply to babies who are only 30 days into this world?

Why is Water Important for Infants?

Before jumping on any conclusions let’s first understand why water consumption can be important especially during infancy when dehydration levels could rise quickly. Unlike adults, infants have incredibly small bodies that do not retain fluids in the way that an adult body does; therefore staying hydrated throughout the day can help flush out toxins from their tiny systems.

In addition to flushing out unwanted wastes from an infant’s digestive tract (quitters never win!), consuming adequate amounts of fluids also helps bolster other critical bodily functions including enabling blood circulation which further supports brain function and enables healthy cell turnover—how cool!

Babies get nearly everything they need nutritionally speaking through breastmilk or formula (a convenient fact considering milk gives us strong bones!). Both breastmilk and formula offer ample forms of vitamins and nutrients perfect for optimal growth—but still may leave some parents wondering at times when “nature” isn’t enough,” ahem…We hear ya’ folks.

When Can Babies Start Drinking Water?

There’s no straight answer since every child develops differently but just like most things else associated with raising tiny humans—it depends! However children could start drinking water after four months once digestion patterns mature (believe it or not even developmental milestones come with prerequisites 🤯).

Until the four-month mark, giving water to babies is generally not recommended (let’s save the uphill battle of digestion till next year kiddo!). This is because newborns get all the fluids they need from breastmilk or formula. Beyond that four month “mouthstone,” introducing small amounts of water could help keep kids adequately hydrated while also helping improve their digestive systems.

Not All Water Is Created Equal

Just like with adults, not all water is created equal for your little one! Unfortunately, tap water isn’t sufficient when it comes to infants under six months old. Pediatricians recommend using sterilized bottled drinkable water or boiled/filtered room-temperature H2O should you decide on offering some much-needed non-milk beverage during this latter stage of infancy.

It might be tempting to give them soda but we promise that’s just a lose-lose option (zero nutritional value and it sure leaves a bad after taste—just kidding).

Remember though: What gives life can take life away too! Giving an infant water in large amounts especially colder versions increases risks associated with unexpected drops in body temperatures which can lead drastic complications such hypothermia—for balance let’s also sing praises high enough for skin-to-skin contact!

How Much Water Is Enough?

As mentioned earlier, infants younger than 6 months do not require additional H20 beyond the breast milk/formula being consumed daily so there shouldn’t really even be a definitive answer until sometime around month number-seven at least!

The choice to introduce small doses (<0.5oz) shouldn’t depend solely on speculation either; always check-in first with your pediatrician who’ll have intimate knowledge around factors tied including appropriate food allergies & intolerance, feeding patterns—and more importantly what specific amount fits safely within his/her system as all cases are unique.

Signs Of Dehydration In Infants

While dehydration and related medical issues rarely occur in healthy newborns, it’s always good to keep an eye out for certain signs particularly during periods of illness or high temperatures around the house.

These Signs Could Include:

  • Decreased urination (no wet diapers for 4 hours or more)

  • Dark yellow pee

  • Dryness of mouth and/or lips

  • Crying without tears.

Remember above tips can also be important nuance alerts that point towards other illnesses like urinary tract infections (usually found on Google page-result no.3—don’t ask us how we know 😉)


The general consensus among most pediatricians is not to give water to infants under four months old since they’re acquiring all their fluids from breastmilk or formula but at about 6-month infants may start getting thirsty enough which “life-water” might adequately quench.

Hydration is key when it comes down to taking care of our tiny humans! Always look out for any changes if alternate drinks are added into a neonate’s diet; never hesitate reaching out your family doctor should any questions arise—they did go through college afterall!

May the liquids forever flow—in reasonable amounts 🙂
