What is an important safety measure regarding water for infants and preschoolers?

An important safety measure regarding water for infants and preschoolers is to never leave them unattended anywhere. This approach is crucial because young children can quickly get into dangerous situations, especially around water. They can accidentally fall in or find ways to access water sources that may not be safe, such as bathtubs, swimming pools, or even buckets of water.

Inattention, even for a short period, can lead to tragic accidents due to their limited understanding of danger and their physical capabilities. It is vital to create a safe environment by being vigilant and ensuring that a responsible adult is always supervising young children when they are near any body of water. This proactive measure is fundamental for preventing drowning, which is a leading cause of injury-related death in young children.

Other options may seem relevant, but they do not address the critical need for constant supervision. For instance, leaving children attended near water sources is dangerous; floaties can provide a false sense of security, and having a lifeguard is not always feasible in many environments.
