This will be DD's first Christmas and I kinda have the feeling I'd like to start a tradition - buy her something which I'll buy a different version of each year and give to her when she's 18 (at the back of my mind, I was thinking glass Christmas tree decorations, but I can't see them lasting one Christmas let alone years). Any suggestions? Hmmm, I just thought that maybe a nice bottle of vintage champagne bought each year...although the chances of those lasting years is pretty slim too! A gold sovereign from each year (although don't know how much they cost)?
