I guess you are the mum - so maybe in your house, you are the boss. If you don't want Santa then that's your choice. Obviously it's something that your parents have gone through with you - a choice they made for you.

I personally think there is no harm in having a bit of fun when you are a child and, to me, Santa (or Father christmas in my house too) is one of the fun things kids can have. We talk to our stuffed toys, yell at monsters, and watch out for fairies. One day the reality will come - but not just yet. I think my kids like those sorts of fun/silly/magic things.
