I ahven't had a baby so i can't comment directly on birthing one but I've been studying teh Pink Kit and it mentions so many great positions for opening up your pelvis. to simplify, try to practice positions that feel like they open you up and concentrate of if they are actually opening you all up or is possibly closing up the back of your pelvis etc. Some good ones are squatting, standing with a leg up, say on the side of the bath, or lying on your side with one leg bent.

I'm curious why you're being induced when you're not even due yet? I'd be personally tying to avoid the induction.
