Hi there,
I'm going through some tough times with my two year old too, and thought I'd throw out a few other thoughts in addition to mari's advice.
With my son, getting to the bottom of *why* he was upset and not settling in bed was the key piece. He was/is having nighttime fears, which are very hard for little onesto articulate. Could this be the case with your daughter?
Also, dreams can really freak them out at this age too, as they don't understand them and they seem very real to them. Hence, adults' constant instance that it's 'just a dream' doesn't do much to make them feel better.
I think it might help if you sit down with her and try to get to the bottom of what's going on. Then, I'd put together a plan to tackle them with perhaps a reward system that used positive reinforcement rather than negative (taking things away), which tends to continually put bedtime in a negative light.
My son's fears have been solved for the time being with lots of talking, reassurance, and extra nightlights and the door wide open when he goes to sleep so he can hear us downstairs. My son does really well when I come back and check on him in five minutes. I try to be right on time too so he builds confidence that I'll come when I say I will. In a way the checking on them is like the wi/wo, but since you're telling them up front 'You try to settle down and close your eyes, and I'll come and check on you in just five mintues" they don't look for you to come back by calling == they know you'll be back and can have confidence in waiting.
