REST!!! Do nothing but rest. I was up and about after c/s 1 and I paid for it dearly -- I was in so much pain. I went to the laundry mat, I carried my 9.9lb baby in the carseat, I went to church... I learned my lesson. With c/s #2, I came home from the hospital, sat on the couch and nursed my baby. I got up to use the bathroom, to eat meals and to go to bed. My mother took care of ds1 and food. My df came over from 82 miles away and vacuumed and swept my home one day. I was back on 2 feet without pain in 10 days!!! I looked better and felt better at 8 days PP after c/s#2 than I did 3 months after c/s#1.
REST was equally important after my HBA2C. I was in bed for 2 1/2 weeks per midwifes orders. I don't know what she told my dh or my mother, but neither one of them would let me up out of bed, not even to sit and have dinner at the table -- sitting was uncomfortable anyway, swelling...
So REST, let the housework go. It will still be there when you are feeling better. Have a friend come in and help, they will come if you ask. It is hard to ask, but trust me you'll be glad you did. Have you dh or dp help out with cooking meals or bringing something home. Order in food. It's hard when there isn't someone to help out, however only time, rest and taking care of yourself will heal you and your dc needs you to be well to care for him or her.
My ds1 did not have a mommy for a long time, I was an emotional wreck on top of not healing well, I ripped my internal stitches and that damage was not fixed until 3 1/2 yrs later with the 2nd c/s.
