Drinking enough water is essential for optimal health and well-being. In fact, roughly 60% of the human body is made up of water. But what does this mean for babies? Should they be drinking water throughout the day like the rest of us? The answer is -- it depends! Keep reading to find out when it is appropriate to start offering baby water and how much they need.

Why is it important for babies to drink water?
Drinking water is important for everyone, including babies, since it has so many vital functions in the body. Water helps to carry nutrients through the body, lubricate joints as well as helps to regulate digestion and body temperature. As adults, we usually think of meeting our water needs by checking in on the water we drink each day. However, babies meet their needs a little bit differently. More on that below!
The American Academy of Pediatrics recommends water for babies as a best-choice beverage alongside breastmilk, formula, and plain milk (for babies older than 12 months).
When can I introduce water to baby?
Babies can begin to have small amounts of water when they start solids around 6 months of age. Offer a few sips of water from an open cup or straw cup at mealtimes. Any water baby drinks at this age is meant to get them used to the taste of plain water and to introduce the skills needed for cup drinking. It is not intended to replace breastmilk or formula which still provide all the fluid your baby needs.
Babies younger than 6 months should not be offered water or any other fluids besides breastmilk or formula. These provide all the fluid they need, even on hot days. Introducing water too early or diluting formula or breastmilk with water can be dangerous for your baby.
How much water should babies drink?
Water needs may vary quite a bit from baby to baby as well as from day to day. Factors such as the weather and activity level can impact needs. Additionally, high-water containing foods such as fruit, vegetables, and soup can contribute to water intake as well.
The best way to know if your baby is adequately hydrated is to watch their diapers. Babies should have about 6 wet diapers a day to indicate they are adequately hydrated. If you aren’t seeing that, watch for other signs of dehydration and talk to your pediatrician.

How should I offer water to baby?
At meals and snacks
Start by offering your baby small amounts of water at meals and snacks. This allows your baby to get used to the taste of plain water and start developing cup drinking skills. It’s best to keep water to about 1-2oz at a time so it doesn’t displace breastmilk or formula.
In a cup
Offering water in a cup helps babies build lifelong skills such as drinking from a cup or straw. Make sure to choose appropriately-sized cups -- they need to fit in their small hands -- and don’t be afraid to help them! Start with small amounts of water and work your way up as baby masters drinking from a cup.
Consider foods
Fruits, vegetables, and anything that is liquid at room temperature, like soup or popsicles, may contribute to your baby’s overall water intake. Sometimes it may feel like your baby isn’t consuming a lot of liquid, but when you take a look at their food intake it may even out a bit.
In a smoothie or popsicle
Making smoothies or popsicles at home is a fun way to offer water as well as to try new fruits and vegetables. They can be especially useful for babies who need extra calories or nutrients because you can pack a lot in a small amount of volume.
Throughout the day
When your baby turns 1 year old, you can begin to have water available more frequently throughout the day. Place a cup out in the kitchen or playroom and let them know they can drink as needed.
What are signs of dehydration in babies?
Dehydration can be dangerous for a baby and severe cases may require hospitalization. If you suspect your baby might be showing signs of dehydration, it’s best to call your pediatrician right away so they can guide you on what’s best to do.
Note: conditions such as vomiting and diarrhea put your baby at increased risk for dehydration.
According to the American Academy of Pediatrics, the following are signs of dehydration:
Mild to moderate dehydration:
Plays less than usual
Less than six wet diapers a day
Dry mouth or cracked lips
Fewer or no tears when crying
Sunken soft spot on head
Severe dehydration (all the symptoms listed above plus):
Very fussy
Excessively sleepy
Sunken eyes
Cool, discolored hands and feet
Wrinkled skin
Only 1 or 2 wet diapers a day
When should I introduce a cup?
Babies can use a cup at about 6 months when they start to eat solids. Most feeding experts recommend starting with an open cup or a straw cup as these cups help to strengthen muscles that are used for eating and chewing. Babies will continue to develop their cup drinking skills through to toddlerhood.

A:
It’s best to offer baby water from a cup if possible. This allows your baby to build important cup drinking skills and helps avoid your baby from consuming too much water. It’s easier to drink from a bottle which may cause them to displace breastmilk, formula, or food with water unintentionally.
