2 ELCSs here!
Be brave and get moving ASAP - pelvic tilt/physio exercises on the bed, then walks to the loo & back once your catheter is out.
Beware trapped wind & constipation! Try and have plenty of fibre & water inamongst the celebratory chocs! Even little shuffles of your hips & bottom whenever you remember will keep you moving.
Be assertive on the ward. Use the bell as & when you need it, especially for the first 24 hours post-birth. If you are in pain, say so.
Stairs can be a bit sore. Go up & down by putting both feet on each step IYSWIM. And think about re-arranging things at home so that stuff you will need doesn't require excessive bending/stretching to get to (eg knickers & socks in the top drawer!) It might be a bit late for this, but I highly recommend one of those high-seated wing-back armchairs. They are SO easy to get in & out of. Low squidgey sofas are not at all comfy as they offer no support. If you get onto one of those with the baby in your arms, you're going to have a hell of a job getting off it again!
If you're going to breastfeed, think about using a desk/dining table sometimes - baby on a pillow on the table while you sit comfortably.
Get loads of proper rest for the first couple of weeks when you are doing your major healing and then things will speed up. Don't push yourself to the very limit from day one, or you'll slow your recovery.
Good luck! You'll be grand!
