How do you get your children to understand when it's time to get up? SIMPLE "'stay in bed until you see the sun!" This updated version of the Gro-clock uses fun images of the stars and sun to communicate when to go back to sleep and when it's time to get up. Due to popular request, this version of the Gro-Clock has a new feature allowing parents to choose whether or not to display the digital clock during the usual stars to sun' countdown. So for older children, they can now start to learn digital time, as well as look for the arrival of the sun!
