I had a section for a breach baby.
Lots of bottled water - I drank gallons of. Can't reiterate enought about the big pants. An eye mask too is also really really useful
Also, not some much what to bring but more what I wish I had know.
More than likely you will be in the theatre by yourself while they prep you - your partner will need to wait outside in the recovery room. My dh found this hard as it was a good 15 mins - they had started the op by the time he was taken through and he had got a bit anxious.
Also I was left on the theatre table (being stiched up) and my dh and new ds were taken back to the recovery room where my ds was bathed. I really really wish I had know in advance that they were going to do this as ds was a small baby and I would rather he hadn't been bathed then - what a shock it must have been for him.
Take all the drugs - don't try to be brave. Don't be surprised it you can't get out of bed to pick you baby up for a good 24 - 36 hrs - don't be scared to use the buzzer if you want to hold your baby - you never get the first few days back again and you may have to be completely dependant on the nurses. You can bring them in cakes the next week!
Also in my hospital they don't suction out the muscus in c section babys. In my room all 4 c section baby's brought up some muscus in the first 48 hrs - it was a bit scary for all of us as they can choke a bit. We were all a bit annoyed we hadn't been told to watch out for it..
Don't mean to scare you but these are things that when I have no 2 I will be asking about and making my wishes a bit clearer.
