Night #2... not so dry

Last night Micah went to bed about 7:00, then Ryan took him to the batheroom about 9:30. He came in at 3:00 and said his bed was wet. I went down and changed the sheets, he changed his pajamas and underwear and went right back to bed. It wasn't bad, but could get annoying if it keeps happening. I remembered something that my sister had used with her oldest. It was a bedwetting alarm. As soon as the sensor senses moisture it sends an alarm sound to wake the child up so he can go to the bathroom. I just ordered one online. I found some for up to $150.00, but I bought one for $20.00. I hope it works as well.
