Also, not to be all hippie but would we not have evolved to want to be held as infants? What species just leaves its young to sleep without physical contact?
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”.
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)
But like anything else, fuck, if it's working for you and the risk is very low, do what you need to do. I avoided it because I kept seeing hellish outcomes but if that's not what's happening for you, go for it.
Our oldest goes to sleep early and will insist on going to sleep when she feels tired and will wake up with me in the morning. Our youngest fights sleep until exhaustion and prefers to sleep in (until 9-10am if allowed). They have been raised exactly the same way.
We take way too much credit for our children's sleep habits.
The opposite: When my kids wake up in the middle of the night if they are alone they freak out. If there is another person there they feel comfort and go back to sleep without waking anyone else up. But YMMV.
Babies want that feeling of comfort, which is why you swaddle.
