The chances of both child and mother surviving birth was almost zero for thousands of years and it's still like that in third world countries. Unsanitary conditions was and still is the cause. So how unsanitary is a stable? Right at the top of the list. In jesus time people were put in sepulchres because no one knew if they were dead for sure. There were many instances where the so-called dead arose and left.
Obviously, this is not true. Humans radiated nearly all over the globe. They are no different from other animals - or do you think they are "special", chosen perhaps? And, certain races have almost no childbirth deaths (either the mother, child or both), while others have a significant percentage - but none has near 100%.
If I were faced with the choice between straw manger bedding in the open air and human "bedding" that had probably not been washed in months in close enclosed quarters with humans which carry human diseases, infections, and parasites - I would choose the straw w the moo cow, any day. Unsanitary is a relative term, in this case.

believe the beliefs of individuals that identify as Christians/jews to be.
