Some good advice here. I’ve had two sections, one elective, one near-emergency.
Don’t underestimate how much that rummaging in your tummy can disturb your digestion! Peppermint oil capsules and prune juice or even fybogel were great for me, I wish I’d known about that the first time around.
Take painkillers regularly, even if you feel ok. Don’t over do it, but also try for really regular little walks around. For my second section, she was delivered at lunchtime, I had my catheter out about 6/7pm ( I had to keep asking as I wanted it out as soon as possible), showered by 8pm. I then made sure I got up and went to the toilet a few times in the night to keep moving. It was hard, of course, but worth it. I was home within 24 hours. BF both after sections without problems.
As someone else said, you won’t be able to get to your bag very easily- I had two big toiletry bags on my pull-over table with everything I needed for the stay; phone, toiletries, snacks. There wasn’t anywhere in the shower i.e. a shelf to put shower gel, shampoo etc & you won’t be able to bend down for it - take a bottle of old school shower gel with a hanging handle. Nightie, not pyjamas to begin with. Very high waisted underwear, leggings etc. Put nappies, wipes, spare clothes etc in the little shelf under the cot and pull it up as close to the bed as you can. With the bed head raised and the cot close, I could manage to reach and pick her up myself in the night (just!).
Avoid bumpy roads and speed humps on the way home! Take all the help you get offered and enjoy the delivery, both of mine were fab, theatre staff brilliant.
