We didn't move DS into his own room until he was sleeping through the night, which was around 11 months. I actually tried several times to move him to his own room before that but he slept so much better in a playpen in our room (and he's a sound sleeper so once he was actually asleep we could still read and talk in bed and not have to tiptoe around him). I think maybe he slept better there because I was able to get to him quicker when he woke up in the middle of the night and so he went back to sleep quicker. I cut off all night feeds at 9 months so after that when he woke in the night i would just give him a soother and lie him back down. It also meant I wouldn't fully wake up (since I cold just lean over and give him the soother) and I could fall back asleep faster. I kind of missed him when we finally did get him moved over.
