D.D.
My son just went through a potty training relapse. The bedwetting was the worse part because even when he was training, he did not wet at night. It was strange that all of a sudden, he started. He's only three, so I know it is a different situation, but here's what I did:
I stopped making a big deal out of it. Believe me, I know that is hard to do when you are completely changing the bed day after day after day. I said nothing if it was wet, but I did congradulate him if it was dry. I also bought some nighttime diapers, and put them on him at night. He hated not wearing his underpants, but I told him I just didn't want him to worry every night. They do sell them in larger sizes. You will hopefully not need more than one package. If she gets upset because they are for babies, just tell her that they are also for kids who need a little help for a while. I don't think my son wet himself at night even once with those diapers on.
I think it is great that you are making special time for her. That's going to make a big difference, too. Good luck!
