In an attempt to figure out just when this labour thing might go down, I employed the resources of Madame Zaritska, internet clairvoyant. Unfortunately, M. Zaritska was less than helpful. She informs me that I am going to have a boy, who will be born bald. She also adds that the weather will be rainy when I go into labour. Meanwhile, three ultrasounds have confirmed that we are having a girl who has lots and lots of hair already. And it's the middle of a summer heat wave in my neck of the woods.
So the wait continues. Still no signs of impending labour. Nothing at all.
