Help Kids Establish Sleep Routine Habits: Younger children cannot fully understand time, the Meteor Routine Helper Sleep Trainer will teach children when it's time to sleep and when it's time to wake up. No more 5 AM morning calls, parents can sleep longer in the morning. HOW IT WORKS Sun, moon, stars, and bright colors will teach children when it's time to sleep or wake up: In the morning, it shows sun and green light when it's OK for children to get out of bed! At night, the clock shows moon and stars, so it's time to go to bed and sleep! Option to turn off the alarm sound and just use red/green light for sleep training. Nursery Night Light & Nap Timer 11 colored lights and 3 warm lights to help children feel safe when sleeping in the dark. The light timer automatically turns off after a certain time. The nap timer function allows you to set a timed countdown for naps or other activities - add a silent alarm! Nursery Sound Machine 17 sleep-promoting sounds to soothe children. Both lights and sounds are fully adjustable and the automatic shut-off timer function (15, 30, 60, constant on) allows you to turn off this toddler alarm clock for a quiet night's sleep.
