I read in one of my pregnancy books that sometime stimulating your nipples can help start labor. It said to be careful in doing so because it can cause strong contractions, so consult your doctor. I was very careful and only did it for 3 days for about 3-5 minutes each nipple. Three days was all it took because I had my LO on May 3rd! I was 38 weeks 3 days! I don't know if this actually helped but I know some of you are ready for your baby to come and who knows it might help!
