The present invention describes a baby carrier rocking device. In one embodiment, the device includes a housing with an imbedded motor, MP3 player, and related components. The housing may feature various shapes and designs, and comprises an aperture at the top portion thereof. The aperture is adapted to hold a first end of an elongated arm therein. The second end of the elongated arm is adapted to rock a baby carrier. In operation, the motor actuates the elongated arm so that it extends upward at a regular interval, contacting a baby carrier and thereby pushing the same in a rocking motion. Each time the elongated arm is extended upward, it falls back down via gravity. In this way, the present invention provides parents or caregivers with a hands-free way to rock a baby carrier.
