What is a possible indication that a baby may be dehydrated?

A dry mouth is a significant indication that a baby may be dehydrated. In infants, adequate hydration typically results in saliva production; thus, a dry mouth can signal that the baby is not receiving enough fluids. When a baby is dehydrated, the body conserves water, leading to decreased saliva and potentially altering the mucous membranes, making them appear dry. This symptom is critical to recognize, as dehydration can lead to more severe complications if not addressed promptly.

In contrast, an increased appetite may actually suggest adequate hydration, while the presence of tears is a sign that the baby is hydrated, as tears are produced through normal hydration levels. Excessive urination can also suggest adequate hydration, as it is a result of fluid intake rather than a sign of dehydration. Therefore, recognizing dry mouth is crucial in assessing an infant's hydration status.
