Managed to lay my hands on a Wii, and the other bits we need (extra remote, nunchuck etc), so it's a VERY expensive Christmas present.
In past years ds has had a main present from us (as in WE asked FC to bring it), and lots of little bits (annuals, story CDs, Hawkins Bazaar bitties), all wrapped in little parcels.
But DS is 8, still believes (I hope). Best way please to explain that the Wii is it, but FC still loves him.
