I agree with @MissisBee re having an open mind about the birth plan. Mine is as follows: get baby out as safely as possible for both of us, and I would prefer a CS over instrumental birth in the event of difficulties as I don't want the risk of pelvic floor damage associated with instrumental birth. I've an appt with my consultant to discuss the hospital protocol for instrumental birth and when it might be necessary over CS so that if the shit does hit the fan I am prepared in advance. I would definitely consider induction as recent evidence suggests there is not much increase in negative outcomes and may even reduce the risk of stillbirth after 39/40 weeks (think it was called ARRIVE trial?). If I'm still pregnant at 40 weeks I will request induction. I just want baby to be here and healthy.
The idea that we should just trust our bodies just rubs me right up the wrong way (sorry). It's only ever people who promote 'natural' birth that say this, no other medical speciality criticise interventions, tell you to trust your body or expect you to deal with excruciating pain without relief. Seeing is natural but nobody is expected to trust their eyes and avoid glasses! Our uteruses and vaginas (and boobs) can be just as dysfunctional as the rest of our organs and unfortunately don't always work the way we want them to!
I think it's great to think about what we all want for birth and to discuss it with our HVPs in advance, but I would also think about 'why' you want what you want. No answer is correct, everyone has their own feelings. My best advice would be try to do whatever you can to relax during birth (deep breaths helped me) and go with the flow.
FWIW my first birth was fast (~4.5hrs) even though I had a number of risk factors. I used gas and air for the pain so it was classed as an achievement in the natural birth circles but I had over absolutely zero control over that outcome! Same as when my boobs decided not to work afterwards. Bodies gonna be bodies!
I hope we all have have the births we dream of (a mild nudge and they glide out painlessly..... is that just me?!) But however baby gets here and however much help we may or may not need with that process, we are all amazing because we grew a person and brought them into the world. Let's fuckin do this lassies! ;)
