I've just put DD2, my last baby, into her bedroom, sharing with ther sister. SHe's 11 months now. I think I decided she needed the bigger cot and the logical thing to do was use that transition as the point for her to move ou t of our room. It's a bit of a wrench, though. I've just been sitting in the rocking chair in their room watching them sleep.
DS was in the crib next to me or in our bed until about 9-10 months.
DD1 co slept most of the time until about 10 months though theoretically she had gone into her own room at 6 month-ish, mainly becasue she was rolling and pulling up to standing so couldn't sleep in the crib.
I'm hoping their sharing will help DD1, too, who really doesn't like sleeping on her own. She was very happy tonight.
