I personally would stay away from the pacifier :) I never gave my kids the option and I feel it saved a fight I've seen with many parents and their kids. I used to watch my kids start to fall asleep and then I'd take them to the crib. They always woke up and cried. I let them cry until they fell asleep. My 18 month old still cries himself to sleep some nights, he was done breast feeding at 9 months. It is better than having a dependancy on a pacifier, a bottle, or some one holding them to sleep.
My cousin used to use the same blanket for every nap and bedtime for her kids. She would swaddle them up and that was a routine for them to sleep. Her 3 year old still sleeps with the same blanket. Some people have put soft music on in the room and that helps their kids to sleep. No matter what you choose to try it will probably take about a week or two to get her into a routine, so be patient.
Good luck !
