Ah, you can't prepare because there's no way of knowing is there?
I have two and their arrivals into the world were completely different (DS took forever , DD was induced, I had no pain but the monitor said I was in labour, she sprang out with only DH as assistance)
Sleep as much as you can, you don't realise how quiet your life was until you have a newborn. We were two adults but this new scrap of humanity ruled us 
Have nice food ready for when you get home but your tastebuds will change , so nice easy edible not too spicy (I couldn't tolerate the sauce in pizza, too spicy ).
Good Luck and keep counting
