yeah apparently its the same with a thunderstorm too!
Elijah was born on the Wed (3 days under) straight after that massive storm we had at Easter... I remember I had a hossy app on the the Tues and driving to the app I looked at all the mess there was and the fact that we'd have had trouble getting there if I'd gone into labour cos roads were blocked and we were cut off apart from one way I think. I can't remember if the storm was 2 or 3 days before.

With Oskar it was exactly 1 week after a new moon and 1 week before full moon (smack bang in the middle - 4 days over.
