Anybody know how to reset this after a first wee sets the alarm off? My daughter used this with the pants for the first time last night. Very sensitive. She had a first tiny dribble when going downstairs to say goodnight to her dad, before she got into bed, and it went off. Due to that dampness it went off every couple of minutes for the next hour. She eventually turned it off, which is not the point. Am I missing something? Should I be doing doing something to the pants or alarm after a wee?
