The original Baby Shusher sleep aid device. Ideal for soothing babies to sleep. Perfect compact size for on-the-go or home sleep support. Includes strap. Designed with babies (and parents) in mind, the Baby Shusher uses a real human "shhh" sound to calm fussiness and help little ones fall asleep faster. Different from white noise, the rhythmic shushing sound mimics the womb, easing newborn cries and creating a soothing sleep environment.
