I borrowed this device from a family member to use with our newborn. We are also following the tips from "Happiest Baby on Block" by Harvey Karp. Karp suggest using a sshhhh-ing sound with newborns to help quiet them to sleep. This machine works as a perfect ssshhh-ing device. Our daughter falls asleep to this machine in her swaddle while we hold and bounce her on an exercise ball every night. An added benefit of the device is the auto-timer, it goes off on its own, so not to run out the batteries. This just might become my standard baby shower gift for friends and family having babies. Great product!
