Well, I know of a young lady at 16 who still bed wet. I can't understand why she can't go to the bathroom at that age? Do you think there is a problem with her bladder or just lazy to ease herself? I don't know how to help her. She is the daughter of my friend. Does any of you have problems like this? Is it normal to some? Please share you experience or your ideas about this.
