Thanka2 you are so right about the fact that you want someone to be mentally focussed on you and supportive. And also about the fact that men can prepare themselves in the same way as women. My husband could not understand at all why i wanted a natural birth, but was prepared to learn. He went to the course with me, read lots and was a fantastic birth partner both times. But he needed to learn what he was getting himself into to get there.
I think that all along in most of my posts regarding pregnancy that maybe the biggest point I was trying to get across that although childbirth is natural, it doesn't really come naturally for most people--whether they are the mother or her birth partner/husband. I think there is this strange belief that one can just go throughout pregnancy and minimally prepare and then go through labor without meds or interventions--that it will all just "come to me" when I'm in the heat of the moment. While this may be the case with a small number of women, I think that most women (and men) who do this really are doing themselves and their babies at a disservice.
Sure, it's fine to take some prenatal classes to become aware of what goes on in birth but some people leave it at that (or don't even take a class)--but honestly that's more "head knowledge" than anything. And there is a vast difference between prenatal classes.
From my experiences (especially this latest birth) I will always advocate over-preparing for labor and birth rather than just assuming that the hospital staff will tell you what to do when you get there. They may order you around (as was the case with my most recent birth) but that doesn't mean they're actually doing what's best for you, your birth partner or baby.
To me, it's like signing up for a marathon run but knowing that you can't really even jog around the block without breathing heavily and just saying to yourself, "Oh, well, in ten months, I'll be ready to run a marathon because I read a book about it." Naw, you have to actively get out there and train--same thing for birth. You've got to learn everything you can about it--and research it and have your mind made up what you want and how you're going to do it and be mentally prepared for all the eventualities that you can.
And yes, I think that most men can also prepare but they have to actively do it--they have to want to be there and expose themselves to the right information and practical training so that when the time comes they can be there--not just physically but also mentally.
