A device which provides an aversive stimulus to a child who bed wets while asleep includes a urine detection pad of absorbent material having wire screen electrodes on both sides thereof, and an electrical circuit including an aversive alarm which is triggered when the detecting pad is moistened by a small amount of urine. A preferred embodiment of the device shuts off the alarm within a short time period if the total amount of urine deposited on the detecting pad is below a given quantity. If more than the allowable quantity of urine is deposited, the alarm continues to expose the child to the aversive stimulus. The device may also feature an adjustable threshold in its circuit to permit variation of the total quantity of urine required to continually energize the alarm, as well as selectable sensitivity of the circuit to the initial deposition of urine so that dampness caused by perspiration or humidity will not trigger the alarm.
