Definitely worth making a note of your preferences relating to your labour and birth. Things to research and consider are:
Who will be with you, are you happy to have a student midwife with you?
What kind of pain relief and coping methods you'd like to use (think about homely remedies like hot water bottles, massage etc too). Anything you'd like to try, anything you'd like to avoid - when it comes to pain relief it's worth checking the effects and side effects for you and baby.
Are there any alternative therapies you'd like to use? Such as hypnotherapy or aromatherapy? If so, who will support you with this? How can the midwife support you with this?
Whether you'd like to use water or not.
Think about 3rd stage of labour (research active vs physiological)
Who will cut the cord - will you want delayed cord clamping (big benefits for baby)
Think about urgent/emergency scenarios - forceps, episiotomy (a cut down below), c-section - what would be your preferences in relation to these? Especially important as there may not be time to discuss any preferences here. E.g. If you go to theatre, do you want skin to skin immediately? Do you want partner there? Do you want delayed cord clamping here?
Skin to skin contact after baby's born - do you want baby dried first or straight onto you? Could midwives weigh baby earlier rather than later so not to disturb skin to skin? Can midwife do top to toe baby check while baby skin to skin? Same goes for vitamin k?
Vitamin K. Are you happy for baby to have it, if so, oral drops or injection
Do you want to keep your placenta?
All useful things that the midwife can read and understand quickly without trying to explain all in detail between contractions.
