Evening primrose oil, insert them vaginally and it helps this out the cervix I've been using them since 34 wks and at my last appt I was 2cm dilated and 80% effaced I think I'm more by now
Lots of sex...eating pineapple... Walking...
Refuse the induction if you don't want one. They are only recommended at 42 weeks (through evidence-based research - any earlier, and it's a litigation based recommendation) and even then you just need to check fluid levels and placenta quality in a scan (an independent scan would be better - my midwife said a lot of doctors just tell you your fluid is too low or placenta is too old anyway, even if it's not, so they get your baby out and stop waiting).
When baby's lungs are ready it will release a hormone to kick start labour... It depends more on your baby than you! But unprotected sex (to soften cervix and promote contractions) and walking (for engaging baby's head) and that scrubbing position mentioned above (for encouraging an anterior position in baby) are great ways to prepare yourself for when baby decides it's ready :)
WHAT I DID TO GET STARTED WAS WASH FLOORS ON MY HANDS AND KNEES AND THAT HELPS WORK AROUND THE PELVIS TO START CONTRACTIONS
