I have 5 children and only 1, my daugher, was a bed wetter.
I agree with the responses on don't make an issue of it with the child. My daughter was also on no drinks after a certain hour at night. She also was a very heavy sleeper - took alot to wake her up at night. I tried to reassure her in the mornings when she had wet the bed that she wasn't in trouble. It was something we would work on together. She didn't get punished for it.
I also took her to a dr. about the problem to see if it was a physical thing causing it. Nothing was wrong. Again, something she would outgrow. And she did!
She still remembers those times, but she remembers them with dignity, not fear, because of how we approached the situation. When the conversation arises about bedwetting, she will be the first to admit she was a bedwetter as a child and how she coped with it. I proud to admit she isn't ashamed to talk about it because she never felt shamed herself during those years.
Work with your child - it isn't something she can control right now. Let her know you love her and it will be okay. She can, of course, help you with washing the sheets, etc. just to help make her know that is some of the responsibility that comes along with wetting the bed. But make it a happy time!
