Hi T.,
Oh my gosh!! My daughter went through a similar phase, but I just got really firm about her keeping the diaper on. I just did not want to deal with constant accidents. It was totally hysterical and cute and I had to do all I could from showing it because I knew that if she sensed I thought it was funny she would keep doing it. She would try removing her diaper as soon as I would put it on and I would just be firm and kept re-doing the tabs (I wish I had heard the trick about putting the diaper on backwards - what a great idea!!) and telling her in a serious voice that it needed to stay on. If she did manage to get it off while sleeping, I again just tried to stay serious - not mad, but just clean up any mess, put the diaper back on and move on. I don't know if my approach really did any good, but she did eventually get over it.
Have you tried pull-ups? Maybe if you tell her they are special and for "Big Girls" only, she would want to keep those on??? Let her pick them out at the store with you, too.
Good luck!!!!!
