Moon Phase Coincidence??

Just wondering if this is something an astrologer may be able to help me with. I am very curious! Please read on.........

Just realised last night that DH, DD and I are all born on a Sunday, and also under the exact same moon phase as each other (half way b/w the last quarter moon and new moon).
I was rather blown away.
Is this merely a coincidence or does anyone know if there's more to this? I would love to hear if there is? I am due to have another little cherub in 8wks time, and if this little one is also to be born on a Sunday b/w the last quarter moon and new moon, then I will most likely go early (9 days early). It shall be very interesting to see what happens.

Love and light

Hmmm.......
A bit of a tricky one I suppose. Anyone have any ideas??
