I hate competitive martyrdom/ism as well. My mum was past master at it, although, to be a little fair to her, she had some excuse (I've now realised since having my boys).
Whenever anything awful happened to me, it "reminded her" of when she lost her 2nd baby. She used it when my fiancé left me. I got the arse, tbh. I said some possibly quite unforgivable things - like "at least the baby didn't have a choice!"
. Thing is, now I realise that Mum had never resolved her grief after the loss of the baby - all sorts of reasons, too long to go into here, but because I had no understanding of the awfulness of it all, it just became tedious that she would always bring it up to show how much worse she had had it than anything any of us could come up with. (I kind of agree with her a bit now - but she's dead, so I can't tell her :( )
But going back to the point in hand - with DS1 I spent a LOT of time in bed, largely because he had a tongue tie and found feeding difficult in any position other than lying down (bonus!) He would feed for up to 2h at a time, so I read a lot while feeding, and dozed. It was blissful (except for the razorblade-through-the-nipple pain associated with him feeding, of course). MIL was staying so she kept the kitchen and washing under control, DH did all the cooking and I just got to be with baby. It was a touch isolated at times, as DH spent more time with his Mum, but meh - better than him bothering me all the time! Didn't get to do it quite the same with DS2, but managed a fair bit of bed rest with him as well 
A friend of mine had a CS and needed 2w bed rest afterwards, she couldn't manage the stairs by herself etc., whereas my sister was up and about in 3 days after both of hers - but there's no prizes for being up and about, my sister just felt ok. I think (and it's only based on a sample of 2 so probably complete bollocks!) that one of the reasons was weight/size-based - my friend was very thin, so her scar was easily stretched whenever she moved, whereas my sis was quite overweight so her scar didn't move at all when she did.
