Comma you need a big hug.
It's so hard to deal with issues that you build up re. hospitals - like my issue about not going back to labour ward!
The difference with this surgery is that you get a lovely prize halfway through, and that helps you to ignore the rest of the procedure and much of the aftermath. It's a really weird experience being awake for it (if you really have issues could you request a general anaesthetic?) but it is literally minutes until this little puffy creature is pulled out, dried and given to you for a cuddle.
The first few days are really tough re. your scar. I found it virtually impossible to sit up from lying without help for a while and rolling over in bed is painful for a good while too. However, I had an emcs which I hear is more difficult to recover quickly from.
re. stomach muscles, your stomach muscles can separate naturally in pg (diastasis recti) and as MrsHappy said they do part them for the surgery. However, this is not a permanent arrangement and you can encourage them back together with appropriate exercise once you have recovered. A physio will take you through things on the ward, and some people swear by Tupler's book on how to get rid of your mummy tummy, but I haven't read it.
Adhesions - I think I had one or two to the LHS of my scar, and they were only a problem when I began pilates. I went to the doctor and he said the best thing to do is to exercise more and tear them apart! I thought they might be a problem in this pg but they haven't been, and they became less of a problem the more toned I became.
I'll be honest and say that I found the recovery hard, but I think that was more to do with having had bad SPD that didn't resolve itself, and having been induced and having laboured before the CS. I also think I was a bit anaemic and DD was a nightmare to feed. Much as I want to avoid a repeat CS, I would be happy to have another one if I was given a concrete reason like a breech baby. I'm almost curious to see what the difference is between an emcs and an elective!
