I'm not against it, I just didn't do it. My daughter slept in our room for a while, but had her crib in there until she started sleeping through the night at 7 or 8 months. Then we moved it back into her room, and she slept in there. Yes I did let her cry it out when nothing was physically wrong with her, I know I'm evil lol, I didn't have to do it often. She's 3 now and prefers to sleep in her bed, she doesn't even want to sleep with me when she's sick. It could be that the parents who accidentally suffocate there children are deep sleepers, or under the influence. I'm not sure, I find it strange too.
