Having no knowledge on the subject, I would think that you could very well go early like with your DS. In your other 2 births, you've identified a reason WHY you went over. In this one, you've already had a C section, and you've already had a VBAC, so there's no 'hidden element' y'know? So I would think you'd be in a calmer place to allow labour to start and progress naturally.

Just my thoughts!
