Hi
We ended up sleeping DS on a mattress on teh floor from around 8 months cause he wouldn't sleep in the cot. It helped immensely.
We have also recently night weaned and having DH get up to him really made a difference - do you have help at night? Sometimes if they're used to feeding to sleep the only thing that works is a complete break for a while, which means someone else needs to settle them.
The no cry sleep solution was helpful for us when DS was younger.
Recently he's also started to cuddle toys in the night a bit, so that is probably also worth a try. Like most things though, it will probably require some persistence on your part to get her to accept different comforts.
Some kids are just very sensitive in that everything upsets their sleep. DS is having a really hard time with teethign at the moment and is getting maybe 8 hours of sleep a night. He's quite, errr, difficult these days. But once he has a break he'll be better (at least for a little while)
good luck with your changes
