In my NCT class, I was the only person who definitely wanted an epidural. One was older and therefore had an open mind - she just wanted her baby however it happened. One was planning a home birth. All the others (5) were booked in for a natural birth in the midwife led unit and reminded me on several occasions about the 'cascade of interventions' - some seemed even a bit evangelical about it all.
Not a single person out of 8 had the birth they wanted or planned for and many felt disappointed as a result. The lesson I learned: birth plans are nice to have (it lets the midwives know what you'd prefer and they will accommodate that as much as possible) but you really can't predict what YOUR labour will be like.
I also wonder about the cascade of interventions hype. Does having an epidural really CAUSE additional interventions? Or is it just LINKED to other interventions because the kind of person who tends to have an epidural is someone who is having a long labour, who are finding the pain unbearable & getting tired... factors that might lead midwives to believe a little extra assistance is needed.
As for me, at 42 weeks I was induced. First they tried the gel (2 applications)... nothing. then they broke my waters.... nothing. then they put me on the syntocin... pretty much nothing - never made it past 6cm. And finally my DD was born 3 days later by EMCS. So definitely not the birth I was planning.
HOWEVER, the good news, is that I had a pain free childbirth. Literally zero pain, because nothing was working, and when they finally put me on the drip, they gave me the epidural too (I was advised there was no point not having it, it wouldn't slow the syntocin down).
So I was happily reading magazines, chatting, sleeping, and even dialing in to conference calls at work all while 'in labour'.
And while I would have preferred to not have a c-section, I have to admit, I couldn't have had a better birth experience. And if anything, in my case I'd say it was being induced that caused the cascade of interventions, not the epidural.
