I think it depends on the woman. All of us recover differently. I had a good recovery and was able to care for my baby on my own post-C-Section, but I had to have access to everything I needed on 1 floor, because stairs were a killer. So I slept in the living room, had the baby in a cot beside me with everything she needed easily within reach, and that is on the same level as one of our bathrooms and our kitchen.
This time around I am going to have a 1 1/2 year old running around on top of having a repeat Section and a newborn, so I am definitely having DH take time off of work and my mother is coming to help out the first week as well. The baby I will be able to lift and care for, my 27 lb wriggly toddler is going to be quite another story!!
