Makes sense to me, as the full moon can play a powerful role in when an expectant human mother will go into labour. When I was pregnant with my little boy, my midwife had 3 clients, one due on the 17th, one due on the 22nd (me) and one due on the 27th. Well along came the full moon on the 22nd and all three of us went into labour. The midwives were busy that weekend! I asked her about it and she said it happens all the time.
