I always go way overboard 
Buying all the little bits is my favourite part though.
Mine always get:
Satsuma
Choc coins
Festive friends
Bubble bath
Soap
Toothbrush
Tree decoration
A Christmassy chocolate figure
Then a few bits of tat- bouncy ball, polystyrene glider, grow your own dinosaur, fortune telling fish, disco duck, racing snails etc. (dd told me a few weeks ago these bits were her favourite part of xmas)
A small present (this year slushy cups and syrup)
A main present that's not THE main present dd- password journal, ds- Lewis Hamilton car.
They don't get books from Father Christmas as books are the one thing I will agree to buying them through the year- FC is all about giving them the stuff I say no to! Apart from toothbrushes and satsumas obviously.
Oh and this year they also have santa egg cups as dd saw them and begged me for one but I said no I'm not bloody buying an egg cup you'll use on one day of the year.
So come on, tell me it's hardly anything and my children are not spoilt brats
