A beeper system that includes a beeper attached to a flexible band. The flexible band is attached to the child, such as around the wrist, waist or neck, to prevent the child from removing the beeper. The beeper is programmed to reach a no shut off mode wherein a speaker outputs an audible output of increasing loudness until the beeper is turned off by keyswitch controlled or kept by the supervising adult. The keyswitch is also used to disconnect the flexible band to allow removal of the beeper. A wearer silence button is provided to allow for a warning period before the no shut off mode is reached.
