There is much debate in the literature about the practice and definition of bed sharing. For the purpose of this statement the term sharing the same sleep surface is used which includes bed sharing and cosleeping practices. Sharing a sleep surface with a baby is a complex issue that encompasses many factors, and there is currently insufficient evidence to issue a blanket statement either for or against this practice. 6
Several studies have demonstrated that babies who sleep in close proximity to their mothers have better outcomes relating to successful initiation and duration of breastfeeding.7-9 A randomised study of infant sleeping location demonstrated that side-car cribs that attach to the mother’s bed are effective in enhancing breastfeeding initiation and preserving infant safety in the postnatal ward.9
I do understand your frustration, but the job of SIDS is to reduce the instances of fatal sleeping accidents and there has been some investigation into co-sleeping. I think the information has been confused with the definition of a sleep surface - beds are certainly safer than sofas and the state of parents also plays a role, but there is evidence that sleep accidents do take place in sharing sleep surfaces, albeit incredibly rare.
