Key Points

✔ Toddlers need around 8 fluid ounces (240 mL) of water per day

Toddlers often need to drink more when they’re active or warm. They can safely drink up to 32 fluid ounces (960 mL) daily after 12 months of age.

✔ Water should be offered on its own in addition to milk feeds

Breast milk and formula can continue to support a toddler’s hydration, but it is important to offer water on its own so they can get into the habit of regularly drinking it as they gradually wean.

✔ Keep water easily accessible to your toddler

Easy access to water helps build the habit of drinking it and fosters their independence, letting them quench their thirst when they need a drink. 

How Much Water Should Toddlers Drink

Water is essential for toddlers after their first birthday. Breast milk and formula still count as sources of hydration, but toddlers need to get into the habit of drinking water daily to help meet their hydration needs at this age. At minimum, toddlers need 8 fluid ounces (240 mL) of water per day, which is equal to one cup, in addition to any breast milk and formula they are drinking. On days when they are very active or the weather is warm, you can offer up to 32 ounces (about 960 mL). Some children may drink slightly more or less based on their individual needs.

At 12 months of age, toddlers often need to slowly work toward consuming the minimum 8 fluid ounces per day. We recommend keeping water easily accessible during the day, and always offering water with meals and snacks. Easy access to water helps build the habit of drinking it and fosters their independence, letting them quench their thirst when they need a drink. 

There are many other ways to get toddlers to drink more water, and you can experiment to see what works for your child. 

How to Get Toddlers to Drink More Water

There are lots of different strategies to get your toddler into a routine of drinking water daily, but one of the best ways is to model how it’s done. Toddlers build habits through repetition and imitation of their caregivers. When they see you regularly drinking water each day, they are more likely to follow your lead. 

Remember: it is normal for some toddlers to drink more water each day, while others drink less. Honor their thirst cues and do not pressure them to drink more than they are interested in drinking.

Toddlers should drink at least 8 fluid ounces (240 mL) of water each day. When they are thirsty for more, offer more. Toddlers can safely drink up to 32 fluid ounces (960 mL) per day. 

Does breast milk count as water intake? 

Yes, but ideally, they are drinking water in addition to breast milk each day. This gets them into the habit of drinking water when they are thirsty. To help them get there, regularly offer water with meals and snacks. You can help them slowly work toward drinking more water as they eat more solid foods and drink less breast milk. 

If I am breastfeeding, does my toddler still need water?

Yes. A breastfed toddler needs to be offered water daily to help them build the habit of drinking water daily. 

After 12 months, should I have water available throughout the day?

Yes. Keep water available throughout the day so it’s readily available for your toddler to quench their thirst. One way to help build the habit is to let your toddler choose a special water bottle that they can keep nearby all day. For older toddlers, you can also tap into their natural desire to “help” by letting them fill up the water by themselves in the morning and when it is empty.

Why won’t my toddler drink water? 

Sometimes toddlers need a little nudge to drink more water. To get them interested, try engaging them in different ways. You can let them pick a favorite cup to put on the table at meal or snack time. You can let them pour water on their own or with a little help from you. You can let them choose mix-ins like berries, lime juice, or mint leaves. You can offer a straw—or let them drink from your straw. The more choice and control you give them, the more likely they are to explore, touch, and hopefully, drink. Check out more ideas to get toddlers to drink more water.
