The funniest bit to me was ringing my Grandparents house at 9am, to tell them that they had a great-grandaughter. There was complete silence and you could hear the confusion.
I had had Christmas dinner in their house the night before (we refused to go to our own parent's houses, as I was NOT staying 160 miles from my hospital on my due date). There were 2 grandparents (then 86), 5 of their 6 kids and 3 husbands/wives, and then 3 grandkids (me - with DH, and my 4 year old and 5 month old cousins - my Dad's the eldest, their dad the youngest). Including my uncle who is a priest.
Dinner was an evening event (I think we ate about 7pm) and as DD had decided to move downwards, I had room for and really really enjoyed 2 helpings of turkey, 2 helpings of pudding, and a glass of wine. We moved to the sitting room, to open the MOUNTAINS of presents at about 9pm. At which point I realised that the "oddness" I'd been feeling all day now had a name - I was having contractions.
So I sit quietly through a few pressies, walk up to the loo and back down, sit again, go put on the kettle as others want tea, stand behind my chair for a while and then sit again. DH is oblivious to all this. The 2 kids are having a ball, and 5 month old shows no signs of needing sleep. Their mum is on 1 side of me, the priest on the other. I hold out until 11.30 - when I think I can plead exhaustion. DH realises as we are saying goodbye (which takes another 20 minutes) that I am breathing a bit funny.
We essentially went home to change out of fancy Christmas clothes into rugby shirt and tracksuit, and back into hospital. My lovely dinner reappeared (boo). I mostly calmly got on with it all.
Mum and Dad, and PIL were all a bit "that's wonderful, talk to you both later, congratulations (yawn), bye now" at shortly after 6. But they had been ready for it at any time.
Grandparents were just speechless as we had "only just left them!". And how they hadn't had a clue what was going on at the time!!
