It automatically teaches your child the sleep moment and the time when your child can get up. As a parent, you set the sleep and wake times once. During sleep time, the display turns blue and the monkey closes its eyes. At wake time, the display turns orange and the monkey opens its eyes. Your child will immediately know when it's time to sleep or to get up. Even if your child wakes up too early, they will know that they need to stay in bed for a while. This naturally benefits the sleep of mom and dad greatly.
