I have had both a VB and an ELCS. I much prefered the VB, experienced wise - I felt eurphoric afterwards and was able to bond with baby very quickly, but then a month later I was back in hospital with retained placenta, and heavy blood loss which left me severely anemic for a long time, so in the end recovery was very long. I should add that my VB was not medicalised, I stayed at home until I was 10cm and then went to a midwife led birth unit. It just goes to show that even non intervention type births can result in crappy recoveries sometimes!
I hated the experience of the ELCS - felt very vulnerable and helpless while it was going on, but did recover quickly (for an ELCS) However, although my recovery was good, I couldnt push a (heavy) pram for ages, lift my toddler up or do a lot of walking for a good few weeks, wheras after the VB I could do these things fine after a few days (but then again, second degree tear made peeing and pooing horrible for a long while!) swings and roundabouts!
It definitely takes weeks to get your tummy muscle strength back - which you need for everything! and only days to recover from an uncomplicated VB, so I can only think that your doctor was talking about recovery time while in the hospital, not complete recovery. I left hospital 24 hours after the CS, but was in bed at home for another week.
Its a very hard decision, and there are possible risks on both sides, when I had to make my decision for the second birth, I asked lots of questions about breastfeeding/bonding/being with baby right after the birth, sometimes having a CS can mean there are different hospital procedures to be followed which may mean you dont get to be with your baby as soon as you would after a VB. If you are planning to breastfeed, let them know, and ask what support you will get.
You say that you use a wheelchair often, perhaps you should ask about how much you will be expected to walk upright and when while recovering, and see if you feel comfortable with the amount. You are asked to stand up straight quite soon (a few hours) after the operation, and then encouraged to walk around a lot, standing up as straight as you can (your instinct is to double over and walk with a stoop - or even better just stay lying in bed!) so as to stretch your tummy muscles and not let the scar form too tight. Apparently if you dont walk around much recovery takes longer.
congratulations on you pregnancy by the way
