E.D.
Well, I was about to recommend a toddler bed, and I see some other moms have done so as well. Your daughter may associate her crib with being sick and afraid, a change might be good for her.
Sorry for all you've been through! It looks like you have probably not had a "normal" schedule for some time now, and kids thrive on schedules and routines. I would suggest getting into a good routine throughout the day, it will take a few days and then your daughter will know what to expect. My 2 year old wakes up at the same time every day, eats the same things, plays, knows when it's nap time, etc. Sounds boring to us, but they love it! Then get into a good bedtime routine. Your daughter needs to feel that bedtime is a good thing, and not scary and upsetting. I start early with my two boys (around 6:45, aim to be in bed asleep no later than 8), they take a bath, put on pjs, brush teeth, stories, drink of water, then lights out. There is always a lot of stalling, we just go back in their room quickly help them out, then say good night. Just be consistent, nurturing and firm. Also, they sleep with a night light, and we leave the door slightly open, with the hall light on. Both boys have lots of stuffed friends in bed with them as well. A little added security never hurts!
