Re: Amish birth center study
The birthing center was run by a least one midwife and a GP. I also know quite a few Amish and they regularly see "English" midwives. In fact my own (English) midwife has quite a large percentage of her practice that is Amish. So I don't think them seeing a non-Amish midwife is that out of the norm. I can see the GP there being more for backup for peace of mind not necessarily delivery.
Emily I agree. But I think a large number of births at a place doesn't necessarily mean the staff is more extended. I think a more accurate way of determining that would be to ask what the staff per patient ratio is. It's possible that the larger place makes more money and has more people on staff per patient. IDK just something to think about.
