My dad has only got me 6 Christmas presents so far how do I politely tell him I’m disappointed as I was expecting a lot more?

I don’t mean to sound a spoilt brat but I don’t get anything during the year I don’t ask for anything either only on Christmas and birthdays so I was expecting a decent amount of presents for both
