Mother–infant co-sleeping represents the most biologically appropriate sleeping arrangement for humans and is both ancient and ubiquitous simply because breast feeding is not possible, nor as easily managed, without it.

Most USA and other western infants die from SIDS or from fatal accidents during solitary sleep outside the supervision of a committed adult. Moreover, the overwhelming number of suspected accidental overlays or fatal accidents occur not within breast feeding–bedsharing communities but in urban poverty, where multiple independent SIDS risk ‘factors’ converge and bottle feeding rather than breastfeeding predominates.

Surely, the fact that in Japan safe bedsharing and futon co-sleeping is increasing as SIDS rates decline to unprecedented levels should raise some doubts about any singular or predictable positive association between bedsharing and SIDS rates. Moreover, data on recent Asian immigrants in the USA lead to an interesting observation: the longer different Asian immigrant sub-groups live in the USA and presumably begin to adopt American life styles, including placing their infants in cribs for night-time sleep rather than co-sleeping, the more the SIDS rates of these ethnic groups begin to rise to match the higher rates of SIDS among whites.

Almost all SIDS deaths associated with parental bedsharing occurred in conjunction with a history of parental drug use and occurred in association with the prone [on the tummy instead of on the back] sleep position or sleep surfaces such as a couch or waterbed.
