Munchkin Shhh Portable Soothing Sound and Light Machine 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 portable soothing sound and light machine 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.
