The Gro Clock is an amazing and a fun way to let your child know when it is time to go to bed and when they have to wake up. You can activate the clock using the buttons on it. When its time to sleep, the stars would come up which disappear over time and then sleeping until the sun shows up. This new version of clock uses fun images of stars and the sun to communicate to your child. Visit: https://www.homehealthcareshoppe.com/gro-clock
