As a kid Father Christmas visited our house on on Christmas Eve night to fill our stockings with lots of small gifts plus the obligatory choc. coins and satusma. Stockings were opened as soon as we woke then the 'proper' presents opened after breakfast.
In hubby's house Santa brought the presents from everyone on christmas eve - i.e. like some sort of delivery service and everything was opened as soon as they woke first thing.
DS1 is now three so this year we need to get our story straight.
Over christmas we cover at least 200 miles, stopping a couple of nights at several sets of relatives. Getting all 'Santa's' deliveries into the boot of the car unnoticed and carting them round 'in secret' plus explaining why half of them are left at home until later (need to fit the travel cot in for ds2) does not fill me with that warm and fuzzy christmas feeling.
How does it work in your house?
