Natural induction of labor

what worked best for you to induce labor naturally? I've been walking around at 3cm dilated for over 2 weeks and I need to get this rolling! I've recently tried using my pump on my nipples (that was a little painful. yay breastfeeding!), walking, bouncing on a ball, sex, nipple stimulation, going up and down steps, dancing... Nothing is working! I would love this little boy to come before Christmas! So what helped break your water and get the show on the road!? Thanks in advance!
