Definitely get your name down - it took us about 6 weeks to get in. We had tried doing exactly what we were taught beforehard at home, but it hadn't worked. Somehow, having someone else there reinforcing that I was doing everything right helped keep me calm and kept her calm too during it all. We were there 4 nights and although our situation wasn't nearly as bad as yours, by the last night she was on track.

They won't be able to stop her waking up, but she will learn that she can go back to sleep all by herself with Mummy and Daddy coming in.
