Totally for fun, completely unscientific but just wondered whether anybody's experimented with any of the old wives' tales -- Chinese calendar, needle test, how you carry, wide nose, etc. -- and actually gotten an accurate result. More than once?
So far our results are split 50-50. The one predictor that seems to work most of the time? The mother-in-law test. Theoretically, your firstborn child is supposed to be the same gender as your mother-in-law's first baby.
