Not in the slightest. I had had a previous post-dates baby (though perfectly healthy) and there was a huge amount of stress with it, so with DD2 I was determined to do absolutely everything I could to avoid going post-dates again (aside from medical induction/C-section of course!)
I had 3 separate sessions of acupuncture, at 41 weeks, 42 weeks and 43 weeks. Not a twinge from any of them. Finally went into labour spontaneously at 43+6 weeks (5 days *later* than my previous post-dates baby!!) so obviously it didn't do a damn thing for me!! (That was also in combination with just about every other 'natural' induction method in the book - I guess my babies just really need to cook longer and don't react well to attempts to hurry them out before they're done ;) )
