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).
