Hi,
I had my c-section in April last year and I was only given about 6 hours notice!! So I was very much like your first one!
Anyway, one thing I would prepare for next time is to pay more attention to my down stairs region - they took to it with an electric razor just before surgery and I think next time I'd consider getting it all waxed off beforehand as I found the re-growth itchy and they did a pretty basic job at it (at the least I'd get it well manicured at the beautician beforehand!).
You go to the c-section in a hospital gown - I was in my room for 3 or 4 hours before and they just came and collected me when it was time to go down to Level 1 where the surgery ward is. They wheeled me down in the bed and wheeled me back in the bed after it was finished. I remember that all jewelry and nail polish had to be off!
I didn't think about the music - I think there was something playing at mine - maybe classical music.. but if you got the choice beforehand that would be great.
I can't remember if there was a dressing gown in the room, it was warm when I was there, but if you feel cozy in your own then you should take it. I wore a hospital gown for a day after the c-section as it was the most comfortable thing and I didn't really get out of bed much for the first 24 hours, but then I swapped to my nightie - loose fitting. And I just used the netting underwear and maternity pads supplied which I found great.
Good Luck.
Belinda
