We have: a stocking each (chocolates, a flip book (a friend makes them for a job, and we get them for free from her) one useful but cheap thing from poundland, an IOU for a game they want or whatever, a small note from FC, and then another poundland one, so total cost is £4 per stocking).
Then, they get two small presents (again, from poundland or the local sweet shop or charity shop, so very cheap). Then they each get a larger present (this year it costs £5 each for them) and a shared larger present (this year it costs £10). Then they have a Christmas treasure hunt for presents (when older, it will probably go under the tree too, but for now, it's a treasure hunt) with small gifts and chocolates.
So in the stocking, there's one (actually probably more, but grouped under 'chocolates'- so about three?)for food, then two paid for, then one physical (they each choose a game or a meal or a day out or whatever) and another one is also free (the note). So five.
Then a further three of their own. Then they get six things from the treasure hunt (all costing £1 or less). Total is fourteen (so quite a lot) plus a shared one, and total cost is, this year, £17 each.
For birthdays, they get one main present and then one small present, and the rest comes from what they are given by other people.
