What is a common sign of dehydration in children?

A sunken fontanelle is a common sign of dehydration in children, particularly infants. This sign occurs because, when the body loses fluids, the soft spots on a baby’s skull (the fontanelles) can become less prominent and appear to be recessed. This is a clear indicator that the child may be experiencing significant fluid loss and requires prompt attention to hydration status.

The other signs mentioned do not indicate dehydration. Normal skin turgor suggests that the skin is well-hydrated, frequent urination often indicates adequate fluid intake rather than dehydration, and a dry cough is typically associated with respiratory issues rather than fluid deficiency. Understanding these signs helps caregivers and healthcare providers identify dehydration early and address it effectively.
