i think if you can get your wishes in writing it's always better - that way you don't forget in the moment

DH and I talked a lot about c/s before DD was born as an "in case it happens" thing - all the things you've mentioned above we discussed, but also what drugs in the post birth period are something to consider - was there anything with Z or J that left you feeling too out of it? type of anaesthetic etc might be worth talking about too

there is still enough that you can have a say in - just because you're choosing the c/s birth doesn't mean you're choosing to be walked all over. you still deserve and empowered birth!
