You need giant pants so they go up much higher than your section scar. I went for m&s full granny pants in 2 sizes bigger :)
For a while, I was on the bed, on a pad (they checked and changed it frequently), with the cathetar in. They checked I could walk after 8 hours or so, and removed the cathetar then, in the hospital bed. I was quite worried about the feeling of that, but I barely noticed it. They gave me hospital pants and a pad then. You won't be discahrged until you've peed enough, they have you use a cardboard bowl thing and show them :/
I didn't have any wind pain, but I took peppermint capsule pills religiously (probably too many, everything was very hazy for me) upon Mumsnet advice, so that might have fixed it. Also on mumsnet advice, I chowed down on orange juice and fig rolls and grapes for a few days, so the first few BMs (sorry TMI) weren't remotely traumatic or any effort on my part!
Walk around asap when you can feel your legs again. Little and often, and straighten your back properly. It's a really weird sensation, like you're being pulled into a hunched position. I believe you're meant to recover faster with very gentle walking in a proper position. I still find the post c-section shuffle funny, I don't think I could walk at full speed for more than a month! But it wans't due to pain, it was just a weird inability to go faster.
We arrived at 8am sharp, met surgeons and other people, they clippered a bit of the hair. The spinal was put in in the operating room - I was very nervous and they let DP come with me for that bit, but they usually prefer to do it alone I think. The first needle was sharp, but it was otherwise fine. Baby was born at 9.30. The spinal did make me itch a lot and shake towards the end, so they gave an antihistamine via drip, although the itching took a couple of hours to calm down. The pre-op midwife told me not to take the morphine or I'd be stuck in there for days, so I didn't. That's the only thing I'll do differently next time, I feel I would have been calmer and recovered better from the shock of it all if I had.
