Why is weighing diapers a preferred method for evaluating fluid volume in infants?

Weighing diapers is a preferred method for evaluating fluid volume in infants because it provides a reliable and direct measurement of urinary output. By weighing a used diaper before and after use, healthcare providers can quantify the amount of urine produced, allowing for an accurate assessment of hydration status and renal function. This method offers a clear indication of fluid balance, which is critical in the management of infants, particularly those who might be at risk for dehydration or fluid overload.

While other methods of assessing fluid volume could be considered, they might not yield the same level of precision when it comes to measuring urine output directly. Consequently, measuring output through this method is essential in making informed clinical decisions regarding an infant's health.
