What is the primary reason children aged 3 months to 3 years must wear swim diapers or tight-fitting pants?

The primary reason children aged 3 months to 3 years must wear swim diapers or tight-fitting pants is to prevent pool contamination. Young children, especially those who are not fully potty trained, may have accidents in the water that can introduce bacteria, viruses, or other contaminants into the pool. Swim diapers are designed to contain fecal matter and prevent it from escaping into the pool water, which helps maintain hygiene and ensures a safe swimming environment for all pool users. Keeping the pool clean is crucial for the health of swimmers, as it helps reduce the risk of waterborne illnesses and maintains the overall quality of the pool water.
