How exciting! Hope all goes well OP!
Make sure you wear big granny pants after that sit above your scar!
When I got home I slept propped up (like you do in hospital) using a V-shape pillow. This made it easier to get in and out of bed for night feeds and I actually found it really comfy! So much so that I kept using it for months, even when I no longer needed to!
I was a bit crap with keeping on top of pain relief when I got home (they offered it like clockwork in recovery unit and on postnatal ward) but it didn’t seem to result in lots of pain. But I have heard from others on Mumsnet who really did feel pain after not taking painkillers regularly, so I would try to keep on top of that!
I don’t think I washed properly for the first day at home while my dressing was still on. At my first home visit, which I think was the day after returning from hospital, the midwife said I could carefully remove my dressing. After dressing was removed I knelt in a shallow bath and had a wash that way for a while. I can’t quite remember how long I did this but I’m sure I read that it’s best not to get the scar too wet for a couple of weeks (not 100% on that though). When I did start taking showers I did my best not to get soap on the scar, just warm water, and I always patted it dry. Used toilet roll to begin with but someone on here suggested dabbing dry with a clean maternity pad instead and I switched to that as I had loads more than I needed!
Make sure you take it easy and don’t push yourself to drive, do long walks with pushchair etc. before you’re ready. I found I was fairly mobile very quickly but always took it easy - going down gently onto my knees when necessary rather than bending, letting DH get things out of top cupboards, take care of loading washing machine, cleaning bathroom etc., taking the stairs very steadily (right foot then left foot onto one stair before moving onto the next). Recovery honestly wasn’t bad at all when being sensible like this. The NHS leaflets made it sound a hell of a lot worse!
