You won’t find it, likely. Also, on the recommendation against co-sleeping, I went looking for the actual data. What I found was not SIDS related, but deaths from being squashed, and quite a few of them. I managed to find a few case studies, and they all included a parent under the influence (alcohol mostly in cars I found) and obese parents.
Regardless of how true it is, the establishment cannot make a recommendation of the “Co sleeping is ok if you don’t drink, not overweight, and a light sleeper” kind, as many of the people in those categories are in denial of being in those categories. so it will be “co sleeping is always dangerous”.
I'm impressed. In the US, such a recommendation would be disastrous and whoever made it would be sued to oblivion ....
But then, you nords leave your babies to sleep in the snow which is perfectly healthy but would get you a visit from child protection services in the US (did not hear of such a case, but have heard of cases for letting 9-year old kids walk from school or play basketball without parental supervision)
