Some great ideas there thanks girls, I have tried the co- sleeping thing, and it has worked up untill recently, now she just fusses and fidgets and no one gets any sleep. I will try going into her and putting the dummy back in and soothing with as little stimulation as possible. I will also try and darken her room a bit I think. Day Light savings start here on Sunday so if it is a daylight thing then maybe that will help (one can only hope).
I guess in the mean time I have to keep telling myself that this can't last forever
