Hi OP, I had an elective a year ago, and I’m having another ELCS in a few weeks.
I found the whole process to be almost entirely painless - from the c section itself to the recovery. It was all perfect.
The first 2-3 days, you pretty much can’t get up without help. So, have someone there to help you, and have everything you need, to hand. I kept a little box with paracetamol, lip balm, tissues, snacks, and lots of bottles of water (so you haven’t got to refill). I’m going to cook 3-4 days of food ahead of time and I’ve arranged to have two adults with me at all times for the first week - my husband and Mum (one for me, one for my first born).
You’re really not incapacitated for very long at all.
My DH lowered me onto the loo for the first couple of days, but I was able to do this myself from day 2 onwards, I had a shower and washed my hair by myself on day 2, too.
We had to take baby to the clinic at 72 hours postpartum, and I walked up three flights of stairs, and had a completely normal experience walking around and carrying the baby.
By 6 days I was having a good walk around the shops and park.
By two weeks I was very much back to normal (for context; we had some v gentle sex on about day 8, and I was driving and walking the dog whilst baby-wearing).
The stairs are fine, surprisingly, even on day one. I found that bending down to the ground is impossible for the first few days. Heavy lifting will set your recovery back, so find another way to get baby on the school run - I would rather wear the baby than deal with the pram.
