Didn't really do one with DS as never saw the same midwife twice through whole of pregnancy and really wasn't sure what choices etc were. My only 'plans' were that I wanted birthing ball and any drugs available - as it was I had 1 hr labour so didn't get a chance for anything and just got on with it.
6 yrs later i'm a bit more aware of options and have a lovely midwife who is very pro-choice. Thinking of making a plan but wondering if anyone ever gets use from them?
