I had a c-section due to a failed induction, but I'm also a doula so I support mothers through all kinds of births. I also have a strong interest in birth choices!
My c-section was pretty ordinary. I was quite sore the following day when I got up to have a shower and I found it difficult getting in and out of bed when my son was crying. By the end of the first week I had stopped pain medication and just had to be careful picking up my son. I really struggled to breastfeed though.
My story seems to be pretty standard, but you do have quite a wide spectrum of experiences. One women I know was told by her doctor in early pregnancy that because she wore a size 4 shoe, she would never be able to give birth naturally and had an elective cs at 38 weeks.
As a c-section is major abdominal surgery, it carries the same risks as other surgeries (eg. heart surgery) because it involves cutting into an organ with a major blood supply. The most common side effect of any major surgery is thrombosis. This mother who was told to have a c-section had to be rushed to ICU the day after she was released from hospital due to a blood clot that reached her lung. She spent 2 weeks in ICU and not being allowed to see her baby.
A vaginal birth has it's own problems, but the risk of death is much much lower. I believe studies show about a 4 times higher maternal death rate for c-section compared to a vaginal delivery. However, because the surgery is being performed so commonly these days this rate may have improved.
From my experience I can only say that it comes down to personal choice. You are the person who will have to live with the results of your choices, and so no family member, friend or medical person should force anything on you - c-section or vaginal birth!
On the other hand, I feel strongly that 40 million years of vaginal birth must have been good for something and we shouldn't be so quick in dismissing the benefits of it!

We also need to remember that the use of c-section is only just reaching a peak and so we don't yet know what the long term outcomes are of babies born this way.
The medical pro's and con's then also need to be weighed against your experience of the birth process. It would be much better to have a pleasant elective c-section than a highly traumatic, but successful, vaginal birth. Dealing with postnatal depression or PTSD from the birth is not the way anyone needs to start adjusting to motherhood!
There is no "easy" way to have a baby, and a vaginal birth is not as terrible or scary as it might seem, just like a c-section might also not be as easy or fuss free as it might seem.
I always recommend mothers to watch this film - "Labouring under and Illusion" - in order to dispel some of the myths about vaginal birth. You can watch the trailer for it on youtube -
It's a fab documentary and very funny, so definitely worth getting hold of a copy of the full thing.
