In our quest for parenting knowledge, we often come across age-old practices and advice from our elders. While some of these traditional remedies and suggestions can be incredibly beneficial, not all of them stand up to modern medical scrutiny. One such piece of advice that has been passed down through generations is the idea of giving water to infants under the age of six months.

Small Stomachs & Nutritional Value:

Babies have small stomachs, and every ounce of nourishment counts. Water offers no nutritional value to young infants. It lacks essential nutrients and calories that are crucial for their growth and development. By providing water, you’re essentially taking up valuable space in their tiny tummies that should be reserved for breast milk or formula, hindering their intake of the nutrients they truly need.

Breast Milk & Formula Hydration:

Breast milk is a remarkable source of hydration, containing approximately 88% water. This high water content is designed to keep your baby properly hydrated during the crucial first six months of life. Formula milk is similarly formulated to provide adequate hydration without the need for additional water. Diluting formula with water not only reduces its nutritional value but also poses health risks.

Water’s Impact on Kidneys:

The kidneys of young infants are still developing and are not equipped to handle excess water. Giving water to babies under 6 months old can strain their immature kidneys and disrupt their delicate electrolyte balance. This disruption can lead to a condition called hyponatremia or water intoxication. Hyponatremia occurs when there’s an imbalance of sodium levels in the blood due to excessive water consumption. This condition can lead to brain swelling, seizures, and in severe cases, even death.

Water Toxicity & Hyponatremia:

Water toxicity, also known as water poisoning, is a serious concern when it comes to infants. When a baby’s kidneys are not fully developed, their ability to process and excrete excess water is limited. This can lead to an accumulation of water in the body, diluting essential electrolytes and causing dangerous imbalances. The consequences of water toxicity can be severe, highlighting the importance of adhering to the no-water guideline.

While it might seem harmless to offer water to a young infant, the reality is that it can have serious consequences for their health and development. Babies are designed to obtain the hydration they need from breast milk or formula, both of which provide the necessary nutrients and water content. Giving water not only displaces valuable nutrients but can also put their delicate kidneys and electrolyte balance at risk.


In summary, the recommendation to avoid giving water to infants under the age of six months is not a baseless tradition but a well-founded piece of advice rooted in the science of infant development. Trusting your doctor’s guidance and staying informed about modern pediatric recommendations is the best way to ensure your child’s health and safety.
