The idea of Santa is lovely and magical for DC who are young enough to believe.
But that belief has to be managed carefully. You have to realise that your DC may well be friends with DC whose parents have shit loads of money and can spend beyond your wildest dreams.
And that leaves your DC wondering why Santa was so much more generous and so much kinder to them than he was to your DC. Weren't they good enough or well behaved enough? Why, when they were so good did Santa leave them so much less than their friends?
It's hard, but the answer has to be that 'Mummy/Daddy or Mummy and Daddy' have to pay Santa for the presents he brings and we have bought the best presents for Santa to bring.' It's hard and it's horrible.
Although that said, when I was 9 I used to love watching Top of the Pops at the height of disco. I was desperate for a sequined boob tube and a pair of those white lycra stretch trousers that all the pop stars wore. I wrote them on my Christmas list and nagged my DM quite a lot.
Instead I got a Snoopy sports bag, the entire set of Enid Blyton's St Claire's books and a new fangled tape recorder/player with two tape albums. Tony Orlando & Dawn and Mama Cass.
As a 9 year old I was massively underwhelmed. It was a really shit present. As a 52 year old I think it was genius!! I bloody love Mama Cass , Tony Orlando & Dawn and Snoopy!
