Every year I start collecting bits and pieces for my kids nice and early to spread the cost over the three months running up to Christmas. This is great but I've got my DD so many things that I know she's going to love I don't honestly know how I'm going to keep my mouth shut and not spoil the surprise for another two and a half months until Christmas Day. I'd happily give her the lot now and then start again - anybody got any tips for keeping Christmas secrets successfully?
