I went into labour on a full moon, and my sister did too 4 weeks later
2nd time round I'm not sure what the moon was doing (presumably not full as 5 1/2 weeks ago ), but when discussing with the midwife whether some times are busier than others she said they get a lot of waters breaking when there is a full moon.
Good luck - how exciting, you get to meet your new DC soon (well within the next 2 weeks at least!)
My friend's a midwife and she says they have to put on extra staff on a full moon as they have so many ladies going into labour. I thought there may've been one last week with 3 celebs giving birth in the same 2 days.
I'm hoping and praying that the full moon does its job for me again this time. It did withholding dd, waters went at 39+6 on the full moon. I'm now 40+5 and feeling very impatient! Seeing midwife this afternoon and hoping she'll do a sweep to increase my chances.
