DS1 (11) needs a few things (clothes etc), I've asked him if he wanted them for Xmas, he was happy with that, so that's good. There may be one or two little things which will be surprised, but there's no one big ticket item.
However DS2 (7) (possibly no longer a believer) doesn't want anything. He hasn't written a letter. He's not that bothered - he likes Xmas but doesn't associate it with getting stuff, or doing anything special (panto, Santa at the garden centre, shopping etc). So he'll get stuff but possibly nothing that he'll really, really be excited about.
How could I have done this different ? Do most kids write lists ? I don't... (Stockings come from Santa here so the lack of a letter doesn't matter in that sense). DS1 wrote a letter a couple of times when he was younger, but asked for snow...
