Car seat reminder system providing a connection between the parent or child caregiver driver of an automobile and the infant or child in a car seat positioned on a seat behind the driver's seat in the automobile. The connection is provided by a connector, such as a string, cord, rope, cable, chain, thread, ribbon, or lacing material, having two ends, with one end connected to the car seat, and the other end connected to the key or other mechanism for starting or otherwise turning on the vehicle. The connector should be sufficiently long to reach between the car seat when it is in place on a seat behind the driver's seat, and the automobile ignition point where the vehicle is turned on or the ignition is activated.
