Re: 2nd VBAC with twins?
I haven't. But...just before my vbac with dd2, I found out she was breech. There was an ob near me who did lots of vaginal breech deliveries, and when I called him up to talk about a breech vbac, he told me that the day before he had done a vbac for twins where both babies were breech! I don't see why you couldn't vbac twins. Most providers would want baby a to be head down though, but obviously there are providers out there who are comfortable delivering the other variations with twins also. Good luck.
