Its is amazing how different the kids are. For Quinn, it took years before she'd let us leave the room before she was alseep. Brock is not that way at all. He could care less about the stories and songs from mom and dad. He "reads" on his own, sings, plays with toys all by himself. He'll come out several times to get a new toy or book, and then go back to his room to continue to play.
Granted, it still takes him at least an hour to fall alseep, but it is all on his own.
