Query: Amazing

My son had been frustrated with his bedwetting because he wasn't able to spend the night at his friends' house. He suggested getting an alarm clock which we thought was loud but he slept so soundly it never woke him up. My husband was very optimistic and didn't want to buy the bedwetting alarm; He kept saying we would work through it but I was getting frustrated going through two sets of sheets each night. I finally (against his wishes) bought the alarm and now we wonder why we have waited so long. This is our fourth week with the alarm; my son was wet the first three nights and has only been wet another two nights. Every morning when he wakes up we put his stars on his progress chart which makes all of us proud and relieved. There is an end in sight.
