Water is essential for adults, playing a vital role in keeping us hydrated and healthy. We’re often told to drink plenty of water throughout the day, and for good reason. However, when it comes to babies, especially newborns and infants under six months old, the rules are completely different. A question many new parents ask is: why can’t babies drink water? It seems counterintuitive, given its importance for adults, but giving water to young babies can actually be harmful.
Breast milk and infant formula are perfectly designed to meet all of a young baby’s nutritional and hydration needs. Paediatricians emphasize that for the first six months of life, babies generally don’t need anything else besides these. Let’s delve into the reasons why water is off-limits for young babies and how to ensure they stay properly hydrated.
Dangers of Water for Babies Under 6 Months
There are several compelling reasons why introducing water to babies younger than six months old is not recommended and can even be dangerous:
Nutrient Displacement and Tiny Stomachs
Babies have very small stomachs, especially in the first few months of life. Every ounce of space in their stomach needs to be filled with nutrient-rich food to support their rapid growth and development. Breast milk and formula are packed with essential calories, vitamins, minerals, and antibodies that babies need.
If a baby’s tiny stomach is filled with water, it leaves less room for breast milk or formula. This can lead to them not getting enough calories and nutrients, potentially hindering their growth and development. Water provides no nutritional value and essentially “fills them up” without providing any benefit.
Risk of Water Intoxication
Perhaps the most serious risk of giving water to young babies is water intoxication, also known as hyponatremia. This condition occurs when there is an excess of water in the body, diluting the concentration of sodium in the bloodstream. Sodium is a crucial electrolyte that plays a vital role in body functions, including nerve and muscle function balance.
Young babies’ kidneys are still immature and not as efficient at processing fluids as adult kidneys. When babies drink too much water, their kidneys can’t get rid of the excess water quickly enough. This leads to a dilution of sodium levels in their body, causing hyponatremia.
Symptoms of water intoxication in babies can include:
- Irritability
- Drowsiness or excessive sleepiness
- Confusion
- Changes in behavior
- Low body temperature (hypothermia)
- Swelling in the face, hands, and feet
- Seizures in severe cases
In rare but severe cases, water intoxication can lead to brain damage and even be fatal. It’s crucial to understand that even a small amount of water can be dangerous for babies under six months because of their size and immature systems.
Sufficient Hydration from Breast Milk and Formula
It’s a common misconception that babies need water in addition to breast milk or formula to stay hydrated. In reality, breast milk and formula are composed of approximately 88% water. This high water content ensures that babies receive all the hydration they need, along with essential nutrients, in the perfect balance.

Therefore, unless specifically advised by a pediatrician in exceptional circumstances, there is absolutely no need to give water to babies under six months old. Breast milk or formula is sufficient to keep them perfectly hydrated and nourished.
Keeping Babies Hydrated in Hot Weather
During hot weather, parents naturally worry about their babies getting dehydrated. However, the solution is not to offer water. Instead, the recommendation remains the same: offer more breast milk or formula. These provide both hydration and the necessary nutrients, even on warmer days.
Breast Milk and Formula are Key
Increasing the frequency of breastfeeding or formula feeding is the best way to ensure your baby stays hydrated during hot weather. Babies will naturally regulate their intake based on their thirst. Offering more feeds throughout the day will help them stay well-hydrated without the risks associated with water consumption.
Signs of Proper Hydration
Instead of worrying about giving water, focus on monitoring your baby for signs of good hydration. The most reliable indicator is the number of wet diapers.
A well-hydrated baby typically:
- Produces 6 to 8 wet diapers in a 24-hour period, even in hot weather.
- Has pale yellow or clear urine.
Other signs of good hydration include moist mucous membranes (lips and gums) and soft skin. If you notice signs of dehydration, such as fewer wet diapers than usual, dark urine, dry mouth, sunken fontanelle (soft spot on the baby’s head), or lethargy, consult your pediatrician immediately.
Introducing Water to Older Babies (6+ Months)
Once your baby reaches six months of age, you can start to introduce small amounts of water. By this age, their kidneys are more developed, and they are also typically starting to eat solid foods, which changes their hydration needs slightly. However, even then, water should be offered in limited quantities and should not replace breast milk or formula as the primary source of nutrition and hydration.
AAP Recommendations
The American Academy of Pediatrics (AAP) provides guidelines for water intake for babies and young children:
- 6-12 months: ½ to 1 cup (4 to 8 ounces) of water per day is acceptable, in addition to breast milk or formula.
- 12-24 months: 1 to 4 cups (8 to 32 ounces) of water per day.
These recommendations are for total daily intake and should be spread throughout the day, not given all at once.
How to Introduce Water
When introducing water to babies around six months old, start with very small amounts, such as 1-2 ounces at a time. Offer water in between meals, not before, to avoid filling them up and interfering with their appetite for breast milk or formula and solid foods.

Sippy Cups vs. Bottles
Consider offering water in a sippy cup rather than a bottle. This helps babies develop new drinking skills and encourages them to sip water slowly, rather than gulping it down as they might from a bottle. Sippy cups also help with the transition away from bottles and can minimize messes as babies learn to drink from them.
Conclusion
In summary, water is not suitable for babies under six months old and can even be dangerous due to the risk of water intoxication and nutrient displacement. Breast milk or formula provides all the hydration and nutrition a young baby needs. For babies six months and older, water can be introduced in small, limited amounts, but breast milk or formula should remain the primary beverage until at least 12 months of age. Always consult with your pediatrician if you have any concerns about your baby’s hydration or feeding. They can provide personalized advice based on your baby’s specific needs and health.
