Basically DS (4.8) asks loads and loads of questions about Santa, for example
How does Santa get so much money to buy all the toys?
How does Santa make the toys?
How are they the same as the ones you can buy in the shops?
Who helps him?
Why are the elves all different colours?
Where do they all live?
What do they do when it's not Christmas?
Why are the Santas you see in the shops not the real Santa?
This happened last year too but it's worse this year. I try to give quite basic answers because for some reason I feel uncomfortable making it all up. I have nothing against the Santa myth and it's very sweet how excited he is about it but he is so inquisitive that the more info I give him the more complex and difficult the questions become...what do you do in this situation?
