Well, it sounds as though everyone is massively busy, whether at work or at home. Maybe these babies are just stunned! Sooner or later, they will get bolshy with us, but external circumstances might have their effect. Last time, I was in the West Country not long before due date (was I in lalaland or what?!) and changed my plans to come home early as I couldn't stand my DF and stepmother arguing. Got home Saturday. Bang. Popped on Monday. T'was a bit disconcerting to imagine I was (a) driven across the country by my hormones or (b) DS was driven out by a sudden feeling of comfort-at-home!
Thanks for the update, seven. I hope you manage to cram in some sleep over the next few days. At least you can put a short-term birth-plan into place (everyone on proper standby, etc.). Good luck!
PullyWoolOver, that is very sweet. Babies are all head and body, so don't worry about the little tummy and legs to start with. I remember how surprised I was to see how very short DS's arms were - they wouldn't go past his ear! His legs were skinny and looked short as well (making his feet look massive). Compare that to the post-adolescent limbs of a grownup, and I feel like a spider in comparison. There's so much growing they can do out of the womb. 
Oh, yes, indeed, I've already got a child's bedwetting sheet in my mat bag, for the car! Valeting fees for minicabs seem to run to about £50, so it seemed a very cheap precaution!
cheeptrick, sorry things are getting tougher with Air....
Is he at all susceptible to flattery, being a "big boy", showing the baby what's what, etc.?
Thanks for the cranberry juice reminder, OiMissus!
