do one for yourself, write down tips like
-distarction methods for during contractions; counting backwards, breathing, imagining you are surfing a wave or whatever!
-different positions that you have practiced, leaning over a ball, rocking etc
-massage techniques that you have worked out with your birth partner (look some up if you dn't have)
- have things planned for the early stages too which might take a while, such as watching a funny film, making a couple of meals to freeze, writing a letter, doing a puzzle, having a glass of wine and 2 paracetamol! -might all seem mad now but it will make you relaxed and make time fly.
for the midwives, ask them not to offer pain releif if you want to try without, once the offer is there it is hard to say no!
also if you have specific requirements such as; you want to create a dark and quiet environment then put this in your plan as your personal space can quite often be ignored at the time. -perhaps prepare a sign for your door that says 'please enter very quietly' -it is amazing how some midwives/syudents/doctors just barge on in knocking as they walk in!
its not just about the drugs and intervention, because that is all stuff you can't really control on a birth plan, or predict, but I guess you coul think of your birthplan as reminding yourself of all the things you can do to avoid the medical stuff.
