A system having a support that supports a child seat and a controller that outputs motion, sound, and/or image signals to be experienced by a child in the child. An actuator connected to the support moves the support responsive to the motion signal, and the corresponding sounds and image signal may be synchronized therewith. A recorder may be used to record motions and sounds from an actual vehicle. A method includes providing a support for the child seat, and producing a motion signal substantially corresponding to the motions experienced by the child in the child seat in the vehicle. The method further includes moving the support responsive to the motion signal for simulating the motions experienced by the child in the child seat when in the vehicle.
