It is a long time ago now - DS about to go off to university - but DD was a 'textbook' vbac after DS was an emergency c-section.
We have a habit of moving house around due dates, so having moved when DS was 6 weeks old (and yes, I did lie on the operating table thinking 'and I'm due to move to another country in a month and a half...how is this going to work???') we were also due to move 2 weeks before DD's due date. I know that, with everything that goes around a house move, the stronger and more mobile that I could be post delivery, the better.
It really helped that there was a clear reason for my CS with DS - he had (still has) an exceptionally large head, and simply got stuck. We're talking 'head the right size for a 6 month old, way off the centile charts' here, not the odd cm or two.
So we had a clear plan, put together and documented with the initial consultants and then reviewed by the consultants in the new hospital after we moved. DD's head was scanned in a late scan. If it had been large, I would have had an elective section. If it turned out to be average, I would have a trial of vaginal labour, with a very low threshold for going straight for c-section.
DD's head was 50th centile, which gave me huge 'yes,I can do this' confidence going into labour. She was born about an hour or so after we reached hospital, absolutely textbook delivery, and I was home within 24 hours.
[Then she refused to feed and DS got first severe croup and then a really scary chest infection and we ended up in and out of medical care for quite some time, and I ended up with PND and hallucinations due to sleep deprivation, but the BIRTH bit at least went to plan!!]
