SIGNS OF DEHYDRATION - In mild dehydration, the mouth may get slightly dry, and urine output may decrease slightly, but a child should still have non-sunken eyes, warm pink fingers and be responsiveness to you. Behavior can range from fussiness irritability to mild decreased activity. In moderate or severe dehydration, the mouth will get dry, urine output will drop (urination less often than every 8 hours), the eyes become sunken and tears may stop. In the infant, the soft spot on the scalp may appear to be sunken in. The fingers often become cool or mottled in appearance. The moderately dehydrated child is often excessively sleepy and is less responsive to normal stimulation. Severe dehydration may be accompanied by complete unresponsiveness. See capillary refill.
