we actually kept the toddler on our floor and baby is in the attic room. She was in our room through night wakings/feedings, but she is a much better sleeper than our toddler, so we kept it this way and its been fine. I have a good monitor, and one floor is not too far to go to get to her, if needed. By contrast, our toddler both wakes at night and also would freak out if he wandered out of his room but was all alone, so we kept him near us. When the baby is a bit older and the two are on the same schedule, they will share a room and I will get my attic office back.
