My daughter wet during the night until 5 1/2. We spoke with the doctor, who said not to worry about it until she's 7 or 8. She was getting so discouraged though and felt bad about herself. I bought one of the alarms from the Bedwetting Store (www.bedwettingstore.com) that has lights and bells and changes each time the child wets so they don't become sensitized to the alarm. That "heavy duty" alarm is recommended for kids who are very heavy sleepers, like my daughter. It worked great for her. We used it for about 3 months. Once they're dry, you keep it on for a few more weeks just to ensure that they're settled. We did a "star chart" to go along with it. Her confidence really boosted when she saw the change from most days not having a star to almost every day having the star. --KOB
