Water for Toddlers and Babies
Do babies need water? When can babies start drinking water? How much should they drink? Here’s everything you need to know about offering water to babies and toddlers.

When can babies drink water?
Most medical organizations recommend introducing small amounts of water to babies at around 6 months of age. Before 6 months, giving water can disrupt essential nutrient intake and cause life-threatening electrolyte imbalances. The American Academy of Pediatrics agrees that small amounts of water are okay once your baby is growing appropriately. Prior to 12 months, water is optional since breast milk or formula provides the hydration needed. When introducing water, it’s important to use an open or straw cup, not a bottle.
How much water can babies have?
At 6 months, the American Academy of Pediatrics suggests offering up to 8 ounces (227 ml) of water per day. However, we recommend limiting intake to 2-4 ounces (59-118 ml) to prevent water from displacing valuable nutrition from breast milk or formula. Check your baby’s hydration status by monitoring wet diapers (4-6 per day) and energy levels. If you’re concerned, contact your pediatrician.

How should water be offered?
The best way to introduce water is through an open cup or straw cup, which helps your baby develop essential cup-drinking skills. Water is tricky for babies to drink because it’s thin and flows quickly, which means they need to develop fast tongue and swallowing muscles. Don’t worry if your baby coughs or sputters at first—this is a sign they’re learning. If coughing continues after several months, consult your pediatrician.
Avoid using a bottle to offer water. Bottles can lead to overhydration and do not encourage oral-motor skills development. Instead, using a small open or straw cup allows your baby to learn how to swallow water safely.
What kind of water can babies drink?
Babies can drink the same water as the rest of the family. Always ensure that the water quality in your area is safe for drinking. If you live in a location with poor water quality, check with your local health department.

Can babies drink sparkling water?
A sip of sparkling water is generally fine, but carbonated drinks can sometimes cause bloating, gas, and reflux. It’s best to limit sparkling water consumption in babies.

If I’m breastfeeding, does my baby need water?
If your baby is under 12 months old, they don’t need extra water. Breast milk is made up of about 87% water, providing all the hydration they need. Once your baby is 12 months or older, water should be offered alongside milk, with a minimum of 8 ounces (237 ml) per day.
How do I know if my child is getting enough water?
For babies under 12 months, water intake isn't usually necessary. To check hydration, observe your baby’s wet diapers (4-6 per day) and their overall energy level. Dehydration signs include chapped lips, few tears when crying, dark urine, sunken eyes, or a sunken soft spot on the head. If you notice any of these signs, contact your pediatrician immediately.
Can I give my baby water from a bottle?
It’s best to avoid giving water in a bottle as it can lead to overhydration, which displaces nutrients. Instead, offer water in an open or straw cup to encourage proper drinking skills and avoid consuming too much water at once.
When should I introduce a cup?
Introduce an open cup or straw cup at 6 months of age with meals. Giving your baby the chance to hold the cup themselves helps foster independence. At first, expect spills and some mess!
Is it okay to give water to a constipated baby?
Yes, offering small amounts of water (less than 4 ounces for babies 6-9 months old and less than 8 ounces for babies 9-12 months old) can help relieve constipation. Along with water, foods like avocado, beans, and prunes can also assist. Always check with your pediatrician if you’re concerned.
Are sippy cups okay?
We recommend avoiding sippy cups and 360-degree cups because they don’t promote oral-motor skill development. Open and straw cups are better choices for helping your baby develop lifelong drinking skills.
Should I offer water throughout the day after 12 months?
Yes, having water available throughout the day, in addition to mealtime, helps maintain hydration and promotes independence in toddlers. The amount of water a toddler needs can vary, depending on their activity level, health status, and the weather. As a caregiver, you can model drinking water throughout the day to encourage healthy habits.
My child is obsessed with water. How do I know if they are drinking too much?
For babies under 12 months, monitor their daily water intake to ensure it doesn’t exceed 8 ounces. Drinking too much water can cause water intoxication, which leads to electrolyte imbalances. Signs of water intoxication include nausea, vomiting, excessive wet diapers, and confusion. If you’re concerned, contact your pediatrician.
