You're on the right track. There's no need to coerce her. Continue to be patient and supportive. At some point (it's really arbitrary when you do it), such as in another six months, if she has not made progress I'd suggest setting a date when all the pull-ups in the house will be gone and not to return. Don't become punitive around this, but
simplySimply sleep insist that, at that point, she must use the potty and pull-ups won't be an option.
You have your child gather up all her diapers and put them in a bag and set them on the toilet. Then when she is asleep the diaper fairy comes and takes the daipers and leaves a big girl present on the potty. So then the diapers are all gone because the diaper fairy took them away. My daughter was fully trained (with no accidents or wanting a diaper) in one day and my son within a couple days. Also a few days before tell her about the diaper fairy and get her excited. With my son (who was a lot like your daughter) I made him prove to the diaper fairy that he could be a big boy. He had to go on the potty everytime for two days before she could come. I even made a big deal and "called" the diaper fairy and told her that he was going potty. (I did it like santa in the fact that only mom knew their number and could talk to them.)
I hope this helps......it really works soooo good!!!
