I have (today) finished shopping for my three kids (DD7, DS5 and DD3).
They each have 11 presents, including stockings (12 including a lindt reindeer I'll buy in the next tesco shop).
I've tried to buy second hand for the toys, where possible this year, as often they just don't get much play, and we only tend to keep them for a year or so and then sell them on.
We then have maybe 6 other people who buy for them.
As you can see, we keep the basics the same and then they circle the (entire) argos catalogue with other things they would like.
