Abstract: A glove apparatus for deterring thumbsucking, including a glove body to which is affixed a battery-operated electrical alarm arrangement. The alarm arrangement includes a module containing a battery, an alarm device, and an electrical contact mounted in the wristband of the glove body for surface contact by the electrical contact with the user's wrist. An electrical wire lead extending through the glove body connects the module electrically with another electrical contact insulatively attached to the outward surface of the thumb portion of the glove body to be exposed outwardly without being in surface or other electrical contact with the user's thumb. When the user inserts the thumb into the mouth, a continuous electrical circuit is completed through the alarm arrangement and through the user's body to enable the battery to activate the alarm device to sound an audible alarm alerting the user to remove the thumb from the mouth.
