Let's share tips of natural ways to get our bodies prepared for labor

I've been reading about red raspberry leaf tea, evening primrose and pineapple. Any other tried and true methods? I'm very active and going to keep working as a nurse until I go into labor.

This is my 4th baby and they said he was 7lbs7ozs at my 36w ultrasound! All of mine were induced. The first at 40w3d and the other two at 38w exactly. My dr said now they don't induce until 39w unless you meet so much criteria. I did show signs of preeclampsia with the last two inductions.
