My daughter also uses an alarm clock to wake herself up in the night, so she can use the toilet (empty her bladder) and not wet the bed. She uses a silent vibration alarm watch when she goes on sleepovers. I don't understand why parents here are so opposed to the idea of their kids getting up in the night to use the toilet. If they empty their bladder in the toilet, they don't wet the bed, and they don't need diapers. It is pretty simple...
