A seat belt attachment apparatus for providing an alert notification that is secured to a conventional seat belt buckle and initiates an audible alert message each time the seat belt buckle is engaged to release the seat belt comprises a mounting member fixedly mounted to the seat belt buckle and an actuator housing is slidably disposed on the mounting member. The actuator housing is positioned such that when it is depressed, it slides into the seat belt buckle's disengaging button, thereby enabling a user to indirectly disengage a locked conventional seat belt assembly by supplying manual pressure in an actuating direction to the actuator housing. This simultaneously causes a sound module integrated with said actuator housing to emit an alert notification concerning a vehicle condition, such as a reminder to not forget a child in the vehicle.
