My first child was born naturally and, although long, it was a wonderful experience and one that I am very glad that I had.
My second child was born by emergency section. The difference was incredible. After the first birth, I was up and about within hours of the birth. I was able to lift DD out of the crib and feed her, and within a few days I went home.
After the CS I could not sit or stand up unaided, had lots of pain and was very low because I couldn't even lift DS out of the crib. I was in hospital for 5 days (don't know if that is more or less than in UK, I live in Germany). I found it difficult to get out of bed for the first week or so. I do have to admit that I was quite overweight and unfit at the time so perhaps that made a difference too.
I do have 2 close friends who raved about their CS, one said she was able to get up unaided less than 24hrs after the op. Both of them recovered much quicker than I did. They both had planned CS so I think that had a lot to do with it.
On the plus side, the bleeding after the birth was a lot less after the CS and the pelvic floor muscles weren't so damaged, so at least I could sneeze without wetting my pants!
The scar looked nasty at first, I was quite upset when I saw it. My Gynie said that the Dr in the hospital didn't do a good job. For a long time I was numb around about the scar. Now, 3 years later, the scar is barely noticible and I have no problems at all there.
Here in Germany, most hospitals will do a CS if the patient wants one, don't know what it is like in UK.
Good luck
