"I'm also having the same debate. I ended up with a crash section with DS, under general anaesthetic."
I'm a gran so don't normally comment on these threads but....
Eldest DD1 had the same experience exactly with DD number 1 and made the same call as you're considering with number 2. She had a fabulous midwife and had a wonderful water birth and the difference in how she felt, physically, not to mention mentally, was immense. Just to reassure you that VBac can work.
All of us who love her would have chosen an elective, after such a scare the first time, but she was right to go with her instinct and every single thing was different. Good luck!
