How early is early?

I am getting a little concerned, as my wife keeps telling me she thinks ‘blimp’ will come early. That on its own doesn’t worry me, but her mobility – or lack of – has reduced an awful lot recently.

Obviously health-wise, it would be better for ‘blimp’ to come later rather then sooner – but it seems nature is not so keen on planning and does things in its own way.

Update: Thankfully ‘early arrival’ symptoms have dissipated.
