Nothing new for me here, my both children sleep with us, not all of the time, but some of the time every night. I heard of children that sleep through the night AND in their own rooms. These are always someone else's children.

Before I had children, I thought that co-sleeping was not something I would do. But every family in the end has to come up with an arrangement that suits its particular needs and this works for us. I would not go to the extreme and advocate co-sleeping as something one has to do. On the other hand, I suspect many parents end up doing it anyway. Many don't tell.
