Hannah is a very considerate and thoughtful child. She's always been quite impressed by Father Christmas' abilities and she's spent some considerable time contemplating how it is he does what he does so well.
I know every family has a slightly different Santa experience. This experience is often a combination of inherited traditions which are combined or which morph into something new.
In our house Father Christmas is treated to a mince pie and a tipple. The tipple varies but I'm pretty sure he's had beer, sherry, port and wine at different times. Rudolph always gets carrot which this year was chopped up at upon request (apparently the other reindeer were losing out to greedy Rudolph.)
Stockings hang from the mantlepiece and are filled sometime between bedtime and wake time.
Santa also provides one present per child, generally one that has been requested via letter. This request has to be reasonable because Santa doesn't look upon greediness favourably. This one present is generally left near the hearth.
Other presents from friends and family are collected under the tree (if our house) or another corner of the sitting room (if we're at Grandma and Grandpa's house).
Hannah has been considering the stocking bit and she has a theory.
She thinks that Santa buys maybe 100 different stocking presents and these will not all be suitable for all children. Some will be better for older girls and some will be better for younger boys but there will be some that are universally appropriate.
What then happens is some sorting so that each child has a number of age appropriate stocking presents allocated for delivery.
The rest is history, or something.
