Abstract: A device for mixing a bottle of baby formula preferably includes a device housing, a motor, a drive linkage and a bottle retainer. The drive linkage includes an eccentric drive disk, a drive arm, a pivoting arm and a pivot mounting base. The pivot mounting base includes a bottle drive shaft. The eccentric drive disk pivots the bottle drive shaft through the drive arm and the pivoting arm. The pivot mounting base is secured to the device housing. The bottle retainer preferably includes a bottle housing, a locking door and a bottle drive shaft boss. The locking door is pivotally retained on an open end of the bottle housing. The bottle drive shaft is retained in the bottle drive shaft boss. The motor rotates the eccentric drive disk, which causes the bottle to shake back and forth. A second embodiment replaces the device housing with a support member.
