With DD1, we kicked her out of our room and into hers at 3.5 months because we were sleep-training her.
DD2 is now just over 2.5 months (almost 12 weeks) and I'm wanting to kick her out NOW. I don't mind the wakeups but the few hours of sleep I do get is very poor quality (I keep waking up at all her movements and even breathing!) that I'm losing my mind.
How old was your baby when they started sleeping in their own room?
