Hmmm, pit is nasty stuff, BTDT! I can see why you want to avoid it. How big was your first? If she was smaller than 10lbs, I would tell your dr that you want to wait until your edd BEFORE you consider induction. If he knows you aren't on board to an induced labor, well, it's difficult to force that on you - just don't show up for the induction. make up any reason that works for you (car broke down, no childcare, etc.)
If you really feel compelled to induce, then really none of the natural induction methods work unless your body is ready. Black/blue cohosh, castor oil, acupressure, evening primrose oil, etc.
