DD2 has been in my room since day 1, first in my bed then into the cot. Its been great.
Just recently its come to a point where I want to move her out cause she gets to distracted from sleep if she hears me in the night lol.
But it was so much easier to have her there, settling, feeding, all of that, plus I found I was more relaxed cause I knew she was safe next to me.
