I can relate to your grandchilds problem. My sister and I wet our beds till we were 12 until it finally ended on its own. We had tried some sort of medication but nothing really worked. That was almost 30 years ago already so perhaps there are some more effective methods or solutions out there today. But one thing I know that was a major factor in our bedwetting problem was the tension in our home. I have heard that that can be a cause and I know in our case it sure was. Don't get overly stressed about it and make it as uneventful and comfortable as possible for the girl, and yes we avoided sleepovers at friends houses till the problem was over. I hope she gets over it soon.
