Here's the deal w/castor oil. You have to be AT LEAST
2 cm dilated for it to work, otherwise, you just get diarrhea and bad stomach cramps. Yes, it can make the baby have a bm and cause pnuemonia (sp?) and other problems. If you do take castor oil when your body is ready for it...BE READY!!! My friend drank 1 tsp and 45 min later her first baby was BORN. I thought about doing it with my son, but never dilated and had to be induced. Some people also think watercress lettuce induces labor, but I ate enough of it at the end that people were starting to look at me weird.
