Catslikefelix - To reiterate, most of the research around Kangaroo Care, i.e more then this one study, (which I'm not even sure is Cochrane approved) involves premature babies, not term babies, so it is comparing babies in NNU vs babies in NNU having Kangaroo care NOT term babies, home with their parents.
Premie babies have different habituation processes, are more easily stressed etc then your nice, bonny term baby.
No one on here has condemned co-sleeping, just explained why it isn't for them. No one minded hearing about how people enjoyed co-sleeping. What people did mind is the statement by one poster that not co-sleeping was damaging their babies for life. I minded that and the attempts to twist research to support that theory, others did too. Not surprising really.
I agree that we should be more open about co-sleeping from a HPC point of view, there's whispers about it from the more breast-feeding related information sources, but nothing more concrete and official.
However, working in an (also deprived) area where there were several deaths relating to possibly incorrect co-sleeping*, I can understand why the back to sleep in a cot message is pushed, there are less variables to go wrong these days with cot sleeping. In more chaotic households, it's valuable to promote the message that your baby should have a safe place to sleep.
*I was on mat leave at the time, when the HV came, she actually asked to see where DD slept. Not sure what she would've done if I'd said no, but I can understand why she did it.
