"Stay in bed until you see the sun!" This clock displays a sleepy star during nighttime hours, and a cheerful sun during the day. Parents choose what time the sun appears, so the child knows when it's ok to get out of bed.
"Stay in bed until you see the sun!" Parents set the clock to display a cheerful smiley sun at progressively later times of morning, training the child to get up only once they “see the sun” This is great!
