DS is the same age...and is also in our room in his crib.
He still BFs at least once per night, sometimes as many as 4 times.
A few weeks ago we all had colds and I had a cough that was keeping DH up and waking DS, so I decided to sleep in another room...I slept in the other room for 3 nights, and DS slept through each night.
We will be moving him to his own room in a couple weeks, once we have painted and gotten new carpet for his room. (This is with the caveat that he will not be nightweaned until age 1, and if he is waking 2-4 times per night he will come back to our room...)
Could you temporarily sleep on the sofa/in a guest room? If your LO doesn't wake as much (or STTN) when you are not nearby, then I would strongly consider moving her to her own room.
As for actually making the transition, I was just going to move the crib, do the bedtime routine, and hope for the best...but I don't actually have any experience transitioning.
