I've never been into CC either, and my DD was quite a bad sleeper (waking wise) sometimes up to 8 or 9 times a night at about 9m. In the end, I did whatever she needed to get her back to sleep (co-sleep, rock etc) It might not be a comfort to know that she still wakes once a night, but to me that is nothing! LOL I am in the habit of giving her a half bottle when she wakes, in her bed, and she goes back to sleep on her own that way and sleeps until 6 or 7.
I know I will eventually have to wean her off that night bottle, but atm it works for us and I see such a huge change in her maturity over the past few months, that I am quite confident she will handle it when the time comes.
I guess the point to all this rambling is, I'm glad I took the slow and gentle approach to sleeping as I see now how comfortable she is with the whole sleep thing, and how much progress she has made.
IMHO your DD sleeps well, and I would say just keep doing what she needs atm to get her through this tougher time. It's probably just a phase, DD goes through them all the time, but always goes back to sleeping well.
Maybe someone else can give you more hope of all-nighters but I HTH a little.
