Shockingly, babies don't need silence to sleep! A mother's womb is actually a loud place, and is comforting to babies. When dealing with a cranky or colicky baby, loud, constant noise can quickly help calm them down, especially when the noise is louder than their own crying.The Shhh...™ was made to give parents a break and designed with science in mind. It features three specific sounds to first calm down an upset baby (shushing noise), lull them into a calm state (heartbeat noise), and eventually keep them asleep (white noise). This portable, battery powered gadget, is a life-saver when baby is away from home, but needs to get some rest.It also features a timer, and nightlight which can even pulse in sync with the noise. Hopefully this soother saves a few parents from running laundry or riding in the car in the middle of the night just to keep their sanity!
