They left out the part where the "good mother" rolled over her own baby two weeks later and everyone just threw up their hands and declared "What can we do, these things just happen, ya' know?"

Co-sleeping is controversial, not one-sided. It seems that co-sleeping increases the risk of smothering but decreases the risk of SIDS, leading to a net decrease in infant mortality. Always be wary of The Seen and The Unseen.

On the other hand, the majority of related studies seem to be observational, rather than interventional, so it's quite possible that both co-sleeping and observed "effects" are the result of some third factor, such as the attitude of the parent. For example, it's likely that a parent who chooses to co-sleep is more well-disposed toward the infant, and is therefore far less likely to kill it deliberately (infanticide), thus making up some unknown decrease in the overall frequency of "SIDS".

Indeed; this also probably explains some of the benefit of room-sharing.
