I'm not trying to fight, just wanting to understand WHY men used to wait outside. Is it because some men only make things worse because they are nervous and agitated? Not sure.
I don't know for sure, this is just a guess...I'm thinking that in former times, the men weren't part of the birth because wives didn't need their husbands for "birth support" because the family unit was larger and men just didn't get involved in these types of things. Think about the 30s/40s in America - you had most families with 4+ children, and they all lived close to relatives (cousins, aunts, etc) and highschool friends (because people lived where they grew up). And people got married earlier, so their aunts/grandparents were much, much younger than today.
If a woman was expecting her first baby, chances are she was in her early 20s, and she had multiple female cousins, friends, aunts, a mother (in her mid 40s) and her granny (in her 60s) available for help, advice, and support both during the birth but also for the ENTIRE 9 months of the pregnancy. Hospitals were also much more staffed than they are today, with there being multiple nuns/nurses everywhere to help a young mother during the delivery.
Husbands were typically busy with other things during the pregnancy months; wives had plenty of help. Guys just didn't get involved with such things because it wasn't a necessity like it is today, since the family unit is destroyed and couples/families are WAY more independent, isolated than in former times. How many couples do you know who live 100s of miles away from their parents/siblings? This is just isn't how a normal society operates and it's not how God designed things, but it's the world we live in...
