This Zazu Sarah sleep trainer helps children learn when to sleep and when to wake using color-changing LED lights and animated open/closed eyes. This uses red for bedtime, orange for an optional 15-minute almost-morning warning, and green to signal go-time, creating clear visual cues that support calmer routines. This also functions as a rechargeable night light, sound machine and alarm clock with five LED colors (30-minute auto shut-off), six soothing melodies, six wake-up tones, and adjustable brightness and volume. This 100% silicone design with an LCD screen and included USB cable is compact for nurseries, toddler rooms and travel while making evenings smoother and mornings brighter.
