Walking and lots of sex. I wouldn't use the oil causeit can just give you terrible diarrhea and that's not good for you or your baby.
You can jump start labor by using a exercise ball, like one of those pilate balls.
Sex for like as long as you can, sex normally works because the penis is hitting the cervix which is causing it to dilate along with putting pressure on the uterus (not a bad or dangerous pressure)
If you do sex be careful so he doesn't put too much pressure on the tummy.
Hot baths, to the temp that you can handle and have like a couple candles in there with you. Obviously they have to be lit. Relax, and think of being in labor
Also, stairs help.
I have heard that jumping jacks help too, but I wouldn't suggest that one. <--- my opinion
Ive heard sex and walking can trigger labor.
Spicy SPICY FOOD!!
HOT HOT baths.. NOT SHOWERS
bounce on an exercise ball
Cator oil... <--THAT WORKS!!
DEEP BACK MASSAGE WITH HEATING OIL!!! (My husband helped with that... and sex after! I was in labor about an hour later!)
