sex...but honestly I was having contractions one night...and me and my husband decided to do the deed to see if it would help...and it just made the contractions go away...lol I was so mad

There's a lot of health benefits for baby staying a little longer though too(: but I've been told all of the above, & raspberry leaf tea but ask your doc about tea first. They say its good for labor, so maybe it'll help put you in labor?

My friend ate pineapple and the next day she went into labor. Heard it helps!

sex, it's the best method (actually orgasm during sex)

sex, walking, bounce on a yoga ball/corner of your bed, hot bath, eat tons of whole fresh pineapple (I think six is the common amount). that's all I can think of off the top of my head right now

birthing ball and sex helped with my daughter
