Why could I not find this invention when my son was born?

These little doodads... Lullabub ...are remote controlled and rock the entire crib gently in 4 user selected motions (simulation of a car ride, boat, womb, or mothers heartbeat) which if you are not a parent, there is this amazing correlation to car rides and the immediate soothing of children. Basically baby wakes up and is not hungry or requiring a change, hit the button and they are rocked back to sleep.....genius. Anyone know if it actually works? If so please comment.
