You will love this if... You're trying to teach your child to understand when it's time to get up? 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. A little bit more info... Glowing screen shows images of stars and sun to communicate 'sleep' and 'wake-up' time. As the child gets older there's an educational option of showing a digital clock during the stars to sun countdown. A great way to start to teach them how to tell the time. Includes fun bedtime story book. Stars go out one-by-one during the night to show the passing of time. Option to set two separate wake-up times (weekday/weekend or night-time/day-time nap). Adjustable screen brightness. Silent operation or optional audible alarm feature. Mains powered (adapter not included) Power cable with USB end is included. Suitable from age 2+ years.
