I'm afraid the NHS are strapped for cash, and this will be on their minds when a c section is considered..as well as the other implications eg not as safe as a vaginal birth.
A normal delivery costs the NHS approx �1,500. A c section is double that. Rightly or wrongly this has to be considered.
So no, you shouldn't be able to choose ~ unless of course you go private!
I thought I might be able to choose a c section for my second baby as both of us nearly died during the ordeal of my first (she was 10lb, I am 5'2", shoulder dystocia...baby sustained fractures during delivery, I lost almost all my blood) but no. I had to have a 'trial of labour' and luckily all went well :o)
Sorry to be so graphic ~ I hate telling people about my first birth experience but in this case there is a valid reason to let you know that the professionals *usually* know the risk of problems you may or may not encounter after you have already been through one birth.
As you had a breech birth the first time round, they may not offer another c section unless this one is breech ~ although the stroke you suffered may have some bearing on their decision as I mentioned before.
