Kick starting labour.....

I'm currently 36 weeks with baby number 7. Each of my babies have gotten bigger. Baby 5 was 9 pound 7 and baby 6 was 10 pound 6 and since I'm not overly big they both got a little stuck during delivery. Because of this the doctors want to let me go to term ( all my babies have gone over) and give me a c-section. I do NOT want a c-section. I have 6 other children who need me plus this little one. But my obstetrician won't even entertain the idea of inducing me 2-3 weeks early. Since all of my previous babies have been between 41 and 43 weeks I have tried as many of the old "wives tales" ways of bringing labour on and none have worked. Has anyone found a successful way to safely kick start labour.
