I could have written the last paragraph of Ellie's post myself!
The second time I went into labour, I made sure I got to the hospital early enough so that if I felt the need of an epidural, I could have one. Epidurals are very common these days, for all sorts of surgical procedures, where it's deemed preferable to a general anaesthetic. First time around, I had hoped to avoid an epidural - because (a) I was a little worried about the 'risks', and (b) I was an earth mother - I was going to open up like a flower and feel at one with the universe, during this awesome thing called childbirth.
With an epidural or a general anaesthetic, there are 'risks' (very, very rarely something goes wrong). But how many people undergo operations without one or the other? And how many people do we all know who've been fine, afterwards.
And as for being an earth mother - well, how you treat the child for the next 18 (or is it 40?) years is the vital thing. How, or even whether, a woman gives birth to a child does not determine what kind of mother she'll be. A child needs a parent, male or female, who can provide security and unconditional love - that's what matters.
Ooops...ranting...sorry, back to the epidural...
I had to keep still for a little while, while they administer the epidural, and I got a bit shaky for a few minutes, at first. After that, it was fine.
I'm afraid I went for a top-up, too, even though I could probably have done without it

- but in the anti-natal classes I attended during my first pregnancy, we had a fantastic physiotherapist (complete with her legendary 'knitted uterus' - for demonstration purposes), who really explained things well, and taught us to practice our 'moves', in the event of us having an epidural - it could be a case that you can't feel the result of your pushing, but if you know what to do, it works out fine. I didn't need to have a forceps delivery - the physio had explained that there's a higher instance of that with an epidural.
I went to a large maternity hospital - the oldest maternity hospital in the world! - and so there wasn't a problem with availability of anaesthetists.
As for having a baby in one's forties - well, lots of women do, and while medically, the 'risks' are higher, these women are closely monitored.
Yes, it makes sense that someone under 30 may have more energy for sleepless nights, and my children were born before I was 30. BUT I noticed that older mothers had a more 'healthy' outlook on lots of things, as regards parenting, when my children started school. Maybe it had something to do with appreciating what's really important, or perhaps they were more content than the younger women, but a few I met were fantastic parents.
