Hi M.,
I have 4 children the oldest got rid of his at 9 months, the next one never took one, the third child took it until she was one and then we "lost it", I new where it was but took my oppurtunity, and the 4th one 6 months likes her pacifier but she only gets it at naptime and bedtime and we take it bye bye just in case.
So where to start I would start with bedtime first, like others have said this will comfort her being in her own bed and not with you. My 2 middle kids sleep in their own beds and from time to time the come and sleep in our bed, mostly my 3 yr old, so don't think that months from now she is regressing because she not.
Here's what worked for me to get my kids to sleep and fall asleep in their beds, on a sunday night we did our nightly bedtime routine (bath, bedtime drink, read a book), then I would go lay in there with them. First starting off it took them 30 minutes or more to fall asleep and I would have to get on to them about laying down and things like this (I started this in June, my son was starting Kindergaten in August and I was having my 4th child in November so I wanted to get them where I could get them in bed and they fall asleep on their own) it took about 2 solid months of me going in there and laying with them and gradualy the falling asleep time got shorter to where I would walk out before they were asleep. I didn't like this at all but it was much less harder this way and alot less tears for all of us, lol.
After you get the bedtime routine and sleeping in her own bed down then you could tackle the pacifier. But also there are a couple of things you could do with the pacifier now....you don't say wether she takes it all day or not so pick whichever is most helpful.
If she does take the pacifier all day start limiting when she can take it, redirect her or even if she asks for it tell her we can't play and suck on our pacifier at the sametime so she either needs to sit in a special seat, lay in her bed, something somewhere, so she doesn't have the best of both worlds, if you know what I'm saying. After you do this for awhile tell her ok we only have the pacifier when we lay down for naptime and bedtime now. If she starts throwing a fit for it tell her to go lay down in her bed and she can have it, but if you need your pacifier than you must need a nap and you have to lay in your bed to have it.
So here's what's going on she's playing hard ball now, she knows that if she throws a big enough fit you will give in. And believe me it's gonna be a whole lot worse before it's better. She is gonna pull out all the stops or she could go with it depends on the child. You will have to be strong and you will probably think she is Linda Blair, lol. You will have to show her who is boss and who is running the show. So far in her 3 yr old life she has and you need to regain your power before it's to late. I don't know if I have much more advice so I hope this helps you in someway, W.
