We are friends with a family we see a couple of times a year. Their children are 12-15, and as ours are about 10 years younger I really don't have a clue what to get them for Christmas. The last couple of years we've got some chocolates and a game they can all play together, which seems to have been played with and which the kids seemed happy with, but now, with the eldest 15, is this still the right sort of thing? Better ideas? We'd be happy to spend about £30 total, which is partly why we get one big thing to share, as £10 doesn't buy much per child!
(The family spend about the same on our kids, so this level seems about right to avoid anyone's embarrassment).
