The VTech Safe & Sound Myla the Monkey Portable Sound Machine Baby Soother's chubby cheeks light up, doing double duty as a soft glow night light to soothe your little one after dark. Plus, a rechargeable battery means no matter how many times you use the sound machine, you won't have to worry about replacing the batteries. Auto shut-off turns the soother off after 60 minutes, so you don't have to slink into the nursery as baby snoozes to hit stop, either.
