Congrats on the success Lisa! If I were you, I would put a pull-up on her, and then go in every couple of hours (as you said) and take her to the washroom. That would work fine. They just don't want to change the kids, but they won't even notice if she has a tiny accident (as long as it is number one). Then, you come in and check her and change her if necessary. I would go for it! That is great news!
Hey SINK... where is your information and photo on Alex's site? We have to know what you look like, so that we can track you down! haha
