Pregnant women spend an awful lot of time thinking about (and 'training for') the birth experience, and often don't give a lot of thought to what will happen if their pregnancy or labour doesn't quite go according to plan. We know that over 25% of births are by c-section, and yet we don't think it will happen to us. We imagine that these births all fall into the 'scary emergency' or 'too posh to push' (hideous expression, which I apologise for having used) categories. In fact, the 25% statistic suggests that in many many cases a fairly 'normal' (by which I mean, no indication that anything is going to go wrong in advance) pregnancy and/or labour will culminate in a c-section, just as in the article.
I believe that it is much harder to deal with 'traumas' (again, probably too strong a word) for which we are unprepared. (The death of a young, healthy person in, say, a hit-and-run incident may bother us more than the death of an elderly person after a long and painful illness. The former seems 'wrong' because we are so unprepared for it.) Thus, women who do suffer from feelings of 'failure' (and I don't think it's that uncommon) after a c-section may do so because they had never 'got their heads around' the idea of giving birth in that way.
Certainly that was my experience. I had placenta praevia and was admitted to hospital at 27 weeks with bleeding. I knew from that point on that a c-section was almost inevitable. It took some time (and I did go through the 'I'm such a failure. My body has let me down' phase) but eventually I did (thanks, I must say, to the patience and understanding of a whole lot of midwives and student midwives who talked it through with me) come to terms with the fact that - as others have said - this was the only safe way for dd to arrive and to ensure my own safety too. DD1's birth was an amazing experience - a totally happy one and one which I will never forget. I wouldn't wish my 10-week hospital stay on anyone, but the upside of it was that I was totally prepared for the birth which I had, and didn't suffer afterwards from it not being the kind of birth (at home, no pain relief, etc.) that I had planned.
I had a VBAC with dd2, but I wouldn't say that it was a better birth... it was just what suited me at that time (without the dodgy placenta!).
I don't know what the point of what I'm saying is. Maybe women should be better prepared for the eventuality of having a c-section (which is, after all, more than 1 in 4) so that it doesn't come as such a shock if it happens? I don't know if that seems defeatist, though? My experience with dd2 suggests that you have to be quite single-minded to get the birth you want, even when all goes well. So maybe if women were 'trained' to 'half-expect' a c-section it would be counterproductive and the c-section rate would rise still further. Not sure what the answer is....
