I would have a list of choices, ie what pain relief you would like, if so and so happens I would like to do this. Ie at what point you would say you prefer a section rather than carry on trying for a vbac, if you are happy to have continuous monitoring or drip.
Things that may help ie staying mobile or water eyc.
Not as a plan more as a guide and to give you and your birth partner ideas, or a Che k list if you like so you are reminded of questions you may like to ask.
Also stuff like do you want immediate skin to skin with baby, would your partner like to cut the cord, would you like to do delayed cord clamping. Do you want the injection for the third stage, vit k for baby etc.
It doesn't have to be a set in stone plan, it's about preferences and then the midwife can help you make informed choices. Even.little things like music, lighting may help you feel more relaxed.
Mine has always said I would like to use water if possible and to stay mobile, this meant when I needed continuous monitoring the midwife knew staying mobile was important so she made sure to help me do this, to sit on birth ball or kneel on bed etc despite the wires.
Also some hospitals have wireless monitoring, some have mobile epidurals.
Are you happy to have a student at the birth or would you rather not.
Mine will say I don't like to be touched in labour, whereas other women find it helpful to have their bsck rubbed... Just little things that it can be useful for your birth partner or midwife to know.
Obviously lots is luck but some things can help labour, I have big babies so staying upright and mobile has helped them deliver being flat on my back as I was for one, slows my labour's.
