alfiesbabe - I agree with you that the longer the birth plan, the more chance of it all going wrong, and therefore disappointment and possibly feelings of failure.
I think its good to have 'birth preferences' as Klaw phrased it, and if it goes well, then great, but a 'plan' is too rigid.
And if you have a 3 page birth plan, I can guarantee that you will be disappointed about something.
But remember that you can actually just talk to the midwife and tell them at the time that you want such and such, or dont want pethidine or whatever. You are actually allowed to discuss things and decide as you go along Remember that its all about informed consent and nothing should be done to you without a full explaination of the pros and cons. So ask for this! As midwives we will not have to live with the consequences of what we do (unless we totally f**k up) but you will live with them for ther rest of your life, so you need to be happy with what is happening to you, or you will have regrets later.
If you do have a plan, make a few copies to take into hospital, and give a copy to each midwife looking after you, that way they will have to read it.
So, if you have a birth preferences / plan, great, if not, then thats no problem!
