J.,
My oldest had a pacifier (we called it a noochie). We tried to transition him slowly.
First, we made it for only in the bed and in the car, times he would be entertaining/soothing himself. We gave him plenty of reminders that when we got out of the car, up from nap, etc. that the noochie had to go to mommy.
Next, we made it for bedtimes only. The pacifier had to stay in the bed. At that point we started to groom him for the final step, no noochies at all.
We told him the noochie fairy took the noochies from kids when they turned 3, so the new babies can have them, BUT she left a GIFT to say THANKS!. I made a point to show him little babies with pacifiers when out at the store, played up how much bigger he was than that.
Finally, I got a basket and we gathered all the pacifiers and left them at the front door with a note from my boy saying something along the lines of "here are my noochies, I want roller blades." He went to bed fine that night, and was thrilled with his roller blades the next day.
The second night when he went to bed he was less pleased, (Why can't the noochie fairy buy them at the store mommy!!)
But I said something about special fairy magic helping the babies sleep. It took him awhile to sleep, but he after that night he was fine. When he did fuss, I reminded him how much he loved his fairy gift.
I would say that if her daddy is coming and going for work, and you're trying to get rid of the pacifier, I would wait a bit to potty train. She's on the young side to begin with, and with all those other transitions she might start to feel stressed about everything.
Good Luck,
J.
