I really wanted a natural waterbirth with DD, and ended up with an emergency CS.

Now, I'm trying for #2 and while I would dearly love a VBAC this time, I also can't stop thinking about the low % that do go wrong and how much I would hate myself if something awful happened. DD was big too (10lb 2oz) and I have been told subsequent babies would probably also be big, if not bigger.I know (and have seen the videos of) women who successfully have VBACs with huge babies but it still worries me.

I guess I'm worried that my anxieties would stuff up the birth process if I were to try a VBAC while thinking all these things.

So, if you had concerns but went through with it, how did you cope? Did it become a non-issue once you were in labour? Or do you feel it made your labour/birth harder than it might otherwise have been?
I would love to get some perspective on this before it blows way out of proportion in my mind.
