relax and enjoy it.
the more you relax the easier it is.
also afterwards i will recommend trying to get up and about within at least 12 hours afterwards, even if its just stand up and walk around the bed. the sooner your up the easier it is to do things for yourself and you heal quicker and with more ease.
if your in pain dont be afraid to ask for morphine, i loved this stuff, literally felt like i could do anything afterwards and couldnt feel anything, not pain at all not even a little niggle.
take a CD of your fav music with you, with elective c-sections sometimes they allow you to have music playing just as long as it doesnt intafere with the surgeon.
if you want your birthing partner to be the one to tell you the sex request this before you go in, any other added extras tell the midwife who takes you down to surgery so she can inform the people in the room.
the spinal is a very weird sensation, you sort of tingle before going numb and they run a cloth down your side to make sure you are numb.
it will feel like someone is doing the dishes in your stomach! you will feel pushing and pulling but no pain. sometimes this can make you sick, they do give you anti sickness stuff before hand but sometimes this does nothing, it also tastes like you are drinking liquid sugar, very sweet yuk.
but all i can realyl say is just relax, breathe and enjoy it. an elective section is definately a nice experience as it is more laid back that an unplanned one and alot calmer.
good luck and hope all goes well. xxx
