This is the way I would think about it, please don't think I am telling you what to do because it's your decision ultimately, but if it were me I would do this...

I would have a lovely Christmas with family & not be recovering from a c/s if I had the choice. I would wait until the 4th. I'd relax & try some natural induction methods - accupuncture, massage etc etc over the next two weeks. If I was sure I wanted a VBAC, I wouldn't take the earlier date when there has been a later date offered. It's another two weeks to allow bub to make their appearance. Who knows with a definitive end in sight bub might surprise you! I know once everything was organised for my "induction" (AROM) with miss J, I relaxed & my waters broke that night.

Again, totally up to you & you know everyone here will support you in whatever you choose, this is just the way that I would proceed if it were my pregnancy Good luck with your decision hun. It sucks that you have to make it, but I'm sure whichever way you go, it will be the perfect decision for you, the new bub & your family
