There's a book called "Good Night, Sleep Tight" that has some great advice about solving sleep problems or transitions. It's by Kim West. Her main method is that you put the kids in their own bed and you sit in a chair next to their bed. Over a period of several nights you move your chair closer to the door, then out into the hall way, etc. While ours have been in their own rooms since they were about 3 months old, we didn't have much issue with getting them TO their beds. However, 3 weeks ago when we took our son's pacifier away, we had a lot of fuss at bed time (as we expected). So after a week of crying and drama we implemented this method. The crying went from an hour down to a half-hour after the first night. Now, 2 weeks after the first "sit-in" we are in the hall way and he's asleep in 10 minutes or less. He'll protest a little at first, get settled after about 2 minutes, then chatter or sing a little until he falls asleep. In one way it's been kind of nice because I use the sitting time to read a book or fold laundry (yes, I drag the laundry basket to the middle of the hall and get to work) or do whatever.
Good luck!
Have I been tempted to run to the store and buy another pacifier? YES! It was hard going from totally peaceful bed time to screaming fits.
Luckily, my husband's resolve is stronger than mine! We'd be back at square one if it was all up to me.
