A warning system for notifying another person when a child is left in a child safety seat. The system recognizes a child in a child safety seat by either a pressure pad or a secured child seat lap belt. The system is activated by the release of the driver's seat belt. Should a child remain in the seat when the driver's seat belt is disengaged, the system alarms notifying the driver of such. The alarm would include a calm audio output such as a lullaby, a song, or a story. The system can be integrated into the OEM features to provide an alert escalation process using a local alert, a vehicle alert, a wireless alert and ultimately a 911 alert.
