Tim,
Well, he could arrive at any moment. Judging by the amount of cleaning and (whisper it... ironing) my wife has been doing this morning, she's had some sort of enormous hormonal rush overnight! That could be an early sign of things starting to happen.
Also, my inlaws - who will be looking after our two girls during the birth - came back from holiday yesterday, so everything is now in place.
We're just waiting.
Neil
