Hi
I had an elective C-sec in Chelsea and Westminster last month. As you say, I had to attend the VBAC course, on a thursday evening, where a midwife explained the pros and cons of having a c-sec and a vaginal delivery to a group of us, and we were then given some information to take home and a phone number to book our one on one appointment.
They can NOT decide for you and they won't. They are very kind and understanding and will do whatever you want. I was very scared of them telling me I had to go for a natural birth after my emergency c-sec with my daughter but the consultant advised I have another c-sec and that was that. The appointment was booked and it was done. No questions and no problems. The midwife will tell you, it's up to you and they'll support your decision, they just want you to make it having all the information beforehand.
I hope that helps
