Hi OP,
I know this thread is a bit out of date, but i though I'd post anyway incase u are still not having any luck...
No-one has mentioned baby whisperer (I don't think... Skim read a bit)
It worked a treat for my DD at 10 months and again recently after a serious illness. I couldn't bear the though of CC, same abandonment issues as mentioned before, but DD didn't sleep for more than a couple of hours at a stretch, ever!
It's the same deal as CC, lots of crying/ teaches them to get to sleep on their own/ generally takes 3 days for then to 'get it', but you're with them the whole time, so they're crying out of frustration rather than fear.
It worked v quickly when I had to do it again recently (she's now 2.3yrs), literally half way through the first night, she just clicked :)
Good luck, I hope u don't resort to CC
:)
