Reply #1: People should do whatever works for them, of course.

My kids went back and forth between the bed and the bassinet for the first few months, then into their own room. We kept each other awake when we slept together, and frankly, we're a family that enjoys our personal space. But I know some families sleep better together. Everyone getting enough high-quality sleep is the most important thing.

I do know a couple families that did co-sleeping when the kids were babies, and then had a lot of trouble changing the rules when they didn't want a three year old in their bed. It can be pretty hard on the kid if they're not used to being alone...
