Deb - being with you through some of your last induction I am just going to disagree with Caro's last statement (not to have a go at you Caro, just that I know Deb pretty well).
The emergency c/s is not something you want as an option. Yes it will always be there as a last resort, but you can't go into this thinkin - well I can always bow out if things get too tough.
You either have to commit to the VBAC, and do everything to support yourself in this endeavour (from educating Neil to getting the right people around you), or you accept the c/s and be proud of that decision.
I dont want you to go through all that labour again, and have the c/s, and feel like you missed out.
Part of your justification for the planned c/s is having more control over how it happens. You were so knackered and things were so hard after Gab's birth, its not something you need to go through unless it absolutely comes to the crunch, specially with a toddler already there.
So yes - go for the VBAC, or go for the planned c/s, but don't have that thought of "oh the emergency c/s is always there if it comes to that" because it wont help you be committed to the whole fight for you to do the VBAC.
I'm sure you know what I mean Deb. And Caro - I'm not having a go at you, or what you said, I just wanted to nip any thoughts out of Deb's head asap
