Yep well I was bigger than pretty much everyone else here when I gave birth to my DS. I was warned by my OBS that I had an 80=90% chance of c section.... scare mongerer!
I ended up having a fantastic, nearly drug free vaginal birth with only small tearing.(only a few sucks on the gas)
My labour was pretty long (a bit over 36 hours all up), but it wasn't ridiculously hard or anything.
I have also come into contact with larger mums who have more often than not had VB's rather than Csects. Csects ar more dangerous for someone with that extra padding.
I WILL be having another VB this time, and I can't wait!
Even though I am big, I can still do what my body was designed to do
Best of luck!
