This alarm has worked so well. During the first 12 days my child went from wetting the bed x 3 a night, not waking to the alarm, to waking up to the alarm to then waking himself up and on night 12 he had a dry night. We are now 5 weeks into using it and my child hasn't wet the bed for almost two weeks. This is the first time in his life he has had dry nights and he is 9.5 yrs old. Honestly life-changing. Thanks.
