What is a common symptom of dehydration in infants?

A common symptom of dehydration in infants is dry, cracked lips. Infants are particularly susceptible to dehydration due to their higher body water content and the fact that they can lose fluids more quickly than older children and adults. When an infant is dehydrated, their body will show visible signs of fluid loss, particularly in areas like the lips, which can become dry and chapped as there is insufficient moisture. This symptom serves as an important indicator for caregivers to assess the hydration status of the infant.

Increased urination is typically a sign of adequate hydration rather than dehydration, as the body's response to excess fluid is to eliminate it. Cold hands and feet may occur in various conditions but are not specific indicators of dehydration; they might indicate poor circulation or other issues. A high fever can be a sign of infection or illness but does not directly signify dehydration, although it can contribute to an increased risk of fluid loss.
