The present device is a vibrating infant bed that gently rocks a baby to sleep by providing a smooth, reciprocating movement in the vertical direction. The vibrating mechanism has an A.C. gear motor which rotates an eccentric cam. A cam follower rises on top of the cam and is mounted to the moving plate. The moving plate is guided to move in the vertical direction by bearings. As the cam rotates, the cam follower moves up and down, and so does the moving plate. A timing switch is connected to the motor and can be pre-set for a selected period of operating time.
