Dear Santa,
I am 6 years old. I hope you and the reindeer are doing great! I have been really good this year. I helped my mom and dad and shared my toys with my friends.
For Christmas, I would really love a [specific toy or gift], because it looks super fun! I also like [another toy or interest], if that helps. I promise to take care of it and share it too!
Thank you, Santa! I will leave cookies and milk for you, and some carrots for the reindeer!
Merry Christmas!
