I'm probably the least twee person you could imagine
but ds1 is in love with our elves (not the 'official' ones). He's not that fussed about whether they grass him up to FC, he just loves playing with them, talking to them, involving them in his Christmas preparations and finding out what mischief they've got up to.
We don't put up tree/decs until the weekend before Christmas, so it helps the dc bridge the gap where everyone else seems to be doing it all as soon as advent starts.
It works for us
