It may seem silly- it's just a word - but "natural" vs. "unnatural" can mean alot.
Not silly, you're bang on. Having a baby is miraculous, no matter what the method he came out. Carrying a child, having him/her develop inside you (with you're doing NOTHING, basically) is a miracle. The last 12-36 hours of how he/she got here is miniscule compared to the 9 months of seeing life grow. (
No offense to adoptive parents: in fact the issue is the same. So you didn't experience the first few months/years of their life. You've experienced and help mold the most important parts!-- I'm going to digress here, forgive me. I actually came to tears when I heard a man on a talk radio show, who was explaining how he and his wife adopted a baby girl from China. When they got her, she was underweight, a bit sickly, reserved. He said, with emotion, that he was amazed at what a stable, loving environment could do. He said that it was like a "switch was flipped" after a few weeks. She was the happiest, most delightful child you could imagine. Of course, he acknowedged that, this is a parent for you.)
Okay, finished with the digression. But I hope that illustrates the priorities when you think of children...
I know that when I had a c-section, I did feel like somehow I failed in that whole process after 24 hours of labor and that having a c-section was an "unnatural" thing. I've spoken to many women along the way who felt the same way
God, and this is what I hate. Go back a few decades, certainly 100 years, mothers where just thankful if they could make it through childbirth alive, and their infants survived at least through year 1. Now, today, with medical advances, we so take healthy childbirth for granted that we demand no less than "perfect" experiences, "perfect outcomes"....
If mom gets a healthy baby, and she is healthy as well, I see NO reason to suggest one birth method is more valid than another.
