We had this issue with our oldest daughter. Everyone at night produces a hormone that causes us not to make urine. Her body was lacking that hormone. She did take the pills, which are the hormone. It was good for her. No side effects. She worn Good Nights before that, but she was getting so old that she wanted it to stop. Her self esteem went WAY up when she stopped wetting herself. I, personally, think the meds were great. She felt so much better with herself and that is worth sooooo much. Now as I said, it can be a hormone missing in the body. For my daughter and her cousin, when her hormones changed when she turned 14, the bed wetting stopped. She is just fine today. Give the meds a thought, don't rule them out. If it doesn't bother your daughter, then great, but if it does help her out with the way she feels about herself and take the meds. Oh, they told me that if a child is wet EVERY night, then it is probably hormones. That was my daughter. Not all kids are wet EVERY night of their lives. Then it is a training thing. Just make sure they are AWAKE when you take them to the bathroom at night or you are still teaching them to wet when they are asleep.
We did use bed alarms for along time. They work great, except you still can't spend the night with friends. It was YEARS of the alarm, for my daughter, because it was a hormone thing not a behavior.
Good luck!!
