I used to work in a hospital and noticed that the birth center, which usually had 2-3 women in it (small town), would suddenly be completely packed every few weeks, but never thought to check the moon phase - d'oh.
I did check the moon phases for my own, my SO's, and my 3 children's births, and both my SO and I, and oldest DC were born within a day of the full moon (maybe full-moon babies flock together?

Astrologically, it usually means one's sun and moon signs are in opposition, actually). My other two were born right on the 3rd quarter, FWIW.
Here's an article I found about this:
http://www.pioneerthinking.com/dr_moonchildbirth.html"Just as some women experience false labor pains, in cases where the water breaking marks the start of childbirth, full moon is the time when it's most likely to happen."And another article: http://www.redorbit.com/news/display...ource=r_health
"The results of previous scientific studies of a possible lunar-labor connection have been mixed. Some studies have shown a relationship between the lunar cycle and an increase in deliveries, but the studies have differed on which moon phase produced the most births."
