An OK to wake clock uses colors, faces or a sun and moon to show a child when it is time to stay in bed and when it is time to get up. Most also work as a night light, and some add sound machines and two alarms. They are designed for younger children who cannot read a clock yet.
The six clocks below range from a color-light clock to character-style models. Features, sizes and power come from each product’s listing page. We have not used these clocks with children ourselves, and we make no claims about sleep results; the listings include sleep-training promises that we leave out.
