I agree--transferring care will NOT necessarily mean another csec. Heck, I accompanied transfer for epidural for a VBA3C (THREE!), and she got her vbac! That is because a) she and baby were ok and b) she knew to repeat these words as often as necessary: "as long as me and my baby are fine, I do not consent to surgery" (and it was necessary to say it multiple times during the 6hrs we were there before birth).
Choose carefully from among your hospital options, and think carefully about what will and will not be ok with you in terms of care, in advance.
As a hb and UC mom, I always had a back up plan. I've heard some moms tell me that is 'negative thinking' but I say, that's hogwash. I had 5 happy hbs including 3 successful UCs--and w/last baby, transfer that ultimately led to csec (my choice, and needed). Having a back up plan helped me stay MORE positive and relaxed, not less so.
Here is the link to my essay on 'alternative birth plan' from my website. It doesn't go into details of possible plans--but is meant as food for thought for families considering what plan to make (all hb fams, not just HBAC). Maybe you will find it helpful as you consider your alternative, 'just in case' plan:http://womynwisespeaks.wordpress.com...e-birth-plans/
