Hello: Under normal dietary conditions, it is advisable to provide plain water in moderation to replenish fluids.
However, if normal eating is not possible and only plain water is given, there is a risk of hypoglycemia and electrolyte imbalance, potentially leading to water intoxication after some time.
Additionally, you may consider using electrolyte solutions suitable for children, which are generally available at pharmacies.
What you mentioned may be a matter of semantics; perhaps you have overthought it.
Foods, formula, fruit juices, and vegetable juices all contain water and electrolytes.
I hope this clarifies your concerns.
Thank you for your message!

The question of whether babies under one year can drink water is a common concern among new parents, often surrounded by myths and misconceptions. The idea that infants should not drink water at all stems from the understanding of their nutritional needs and the potential risks associated with excessive water intake.

Firstly, it is important to note that infants receive the majority of their hydration from breast milk or formula, which are designed to meet their nutritional and hydration needs. For babies under six months, exclusive breastfeeding or formula feeding is recommended, as these provide adequate hydration and nutrition without the need for additional water. Introducing water before six months can lead to water intoxication, a condition that occurs when excessive water dilutes the sodium levels in the body, potentially leading to serious health issues, including seizures and even death.

As babies grow and begin to eat solid foods, typically around six months, small amounts of water can be introduced. The general guideline is that once a baby starts consuming solid foods, small sips of water can be offered to help with hydration, especially in hot weather or if the baby is ill. However, it is crucial to ensure that water intake does not replace breast milk or formula, which are still essential for their growth and development.

The concern about water intoxication is valid, particularly in infants under six months. Their kidneys are not fully developed, making them less capable of handling excess water. Symptoms of water intoxication can include irritability, drowsiness, and swelling. Therefore, it is essential to monitor the amount of water given to infants and to prioritize breast milk or formula as their primary source of hydration.

For parents wondering how to ensure their child is adequately hydrated, the best approach is to focus on their milk intake. If a baby is feeding well and producing an adequate number of wet diapers (typically six or more per day), they are likely getting enough hydration. Once the baby reaches six months, parents can start introducing small amounts of water, but it should not exceed a few ounces per day.

In summary, while it is not accurate to say that babies under one year cannot drink any water at all, it is essential to approach this with caution. For infants under six months, exclusive breastfeeding or formula feeding is crucial, and water should be avoided to prevent the risk of water intoxication. After six months, small amounts of water can be introduced alongside solid foods, but breast milk or formula should remain the primary source of nutrition and hydration. Always consult with a pediatrician if there are concerns about hydration or nutrition for your baby.
