Davy the dog is a sleep trainer with alarm clock and nightlight in one. It helps children to understand when to stay in bed and when it is OK to get up. When Davy's eyes are closed and the clock is red it means bedtime. An orange screen with Davy's eyes still closed means your little one has to wait only half an hour before. Davy's eyes open and the screen turns green. That means time to get up!, You can also set a naptime for the ones that sleep during the day. Optional is to choose from 3 alarm sounds with adjustable volume. Davy's nightlight is dimmable and could stay lit continuously or switch off automatically after 5, 15, 30 or 60 minutes. Powered by 4x AA (not included) or USB cable (included). Input 5V, 500mA.
