A system for alerting someone that a child is in a safety seat in a vehicle includes a proximity sensor/transmitter and a receiver. The receiver is removably mounted on a child's car seat and the proximity sensor/transmitter remains on the car seat. After a child is placed in the seat, the receiver is removed from the seat and placed on the driver or other adult responsible for the child. The receiver can be placed in the person's purse or on their person. If the person moves away from the vehicle without disabling the transmitter on the car seat will activate that receiver as soon as the receiver has moved a prescribed distance away from the vehicle. The receiver will generate a signal, such as an audible and/or visible signal, which will attract the attention of the person carrying the receiver. The signal will be generated in a continuous manner until the transmitter is disabled, which can only be done after the child is removed from the seat. The system further includes a light on the transmitter that is activated when the receiver is removed from the seat to signal that the system is active.
