Labor-induction folklore is like hiccup remedies: the purpose is to keep you occupied and your friends amused until nature can take its course.
So far I'm still sticking to the versions that are fun. Walking (well, sort of). Fresh pineapple. Foot rubs. Etc. Some people apparently go for eggplant parmigiana, but others say it's the basil and oregano that are important, which is good because eggplant is a vegetable towards which I harbor a deep skepticism, no matter how thoroughly it is parmigianed.
The way I figure it, people must have gone into labor while doing almost everything except flying stealth bombers. One can therefore pretty much try anything to go into labor. Murphy's Law seems a good place to start:
Will removing the toilet from the main bathroom induce labor?
Taking DOB's spare jeans out of the hospital bag?
Having the house full of people?
So far, no luck with those. We considered trying attending a distant event, but it was too much trouble.
I also theorize that watching suspenseful movies should help. However, so far Alfred Hitchcock has done nothing for me.
Now it comes down to whatever I want to do, or whatever anyone else is trying to talk me into doing. Hey, maybe killing spiders induces labor! Cooking supper! Bopping DOB!
You never know.
