Why Babies Don’t Need Water Before Six Months:

For the first six months of life, breast milk or formula provides all the hydration a baby needs. Breast milk is especially rich in water content, offering just the right balance of nutrients and fluids. Even in hot weather, babies are generally hydrated adequately by breast milk or formula alone. Adding water too early can interfere with this balance, reducing the intake of essential nutrients, and in rare cases, lead to a dangerous condition known as water intoxication.

Water Intoxication in Babies:

Introducing water too early can lead to a dilution of sodium levels in the baby’s blood, which can disrupt normal body functions and, in extreme cases, cause seizures or even death. This is rare but underscores the importance of waiting for the right time to give water.

When to Start Giving Babies Water:

Around six months of age, babies begin transitioning to solid foods. This is also the time when they can start having small amounts of water. But even at this age, water intake should be kept minimal, as breast milk or formula will still be their main source of hydration. Offering a few sips of water during meals or after meals is enough to help them get used to drinking water without filling up.

How Much Water Should a Baby Have?

• 6–12 Months: At this stage, babies can have a few sips of water with meals, especially if they are eating solid foods. However, they still don’t need much – around 60–120 ml (2–4 ounces) a day is sufficient. Too much water can interfere with nutrient absorption from breast milk or formula, so keep it to small, occasional sips.
• 12 Months and Beyond: Once a baby turns one, they can start drinking water more freely. This is the time to introduce water as a regular part of their diet, as they begin to eat a wider variety of foods and rely less on breast milk or formula. Aiming for around 1–1.5 cups (240–360 ml) per day is ideal, but be mindful of their individual needs and preferences.

Tips for Introducing Water to Your Baby: 

• Use a Cup: At six months, introduce a small, open cup or a sippy cup to help them learn to drink independently. This is a great way to encourage motor skills and avoid reliance on bottles.
• Choose the Right Temperature: Some babies may prefer room-temperature water, while others might like it slightly warm, especially if they’re used to warm milk.
• Avoid Sugary Drinks: Introducing water alongside solid foods helps avoid the habit of sugary drinks. Always avoid juices and sugary drinks for babies under one year and keep them limited even after that, as they can contribute to tooth decay and unhealthy weight gain.
• Make It a Routine: Offer small sips during meals or after a meal, making water a natural part of mealtime. This can help prevent them from filling up on water, which could reduce their intake of milk and food.

Signs of Dehydration in Babies: 

Though it’s rare for babies to become dehydrated if they’re being breastfed or formula-fed properly, it’s still good to be aware of signs of dehydration, especially when they’re sick or during hot weather. Look out for:

• Fewer wet nappies (fewer than six a day)
• Dark yellow urine
• Lethargy or irritability
• Dry lips and mouth
• Sunken eyes

If you’re concerned, consult your paediatrician for advice on how best to keep your baby hydrated.

Final Thoughts:

Introducing water to babies is an exciting step in their development, but timing is essential. Wait until six months before giving water, and even then, keep it to small sips until they’re over a year old. Starting healthy drinking habits early on sets the stage for a lifetime of good hydration and health. As always, speak to your healthcare provider if you have questions or concerns about your baby’s diet or hydration needs.
