If my first reply shows up later I am sorry, it disappeared. This story was so familiar, its like I lived it. Actually I have been avoiding this Elf on the Shelf & Randall Reindeer for over 19 years, not because I hate but like you I felt it may be to much pressure on a kid. I remember as well trying to be good enough for Santa's eyes, let alone another.
My oldest would write her letter to Santa by Halloween and it was extensive. She was four and was learning to write so although my first words were 'don't you think I'll forget to send it' her reply was 'don't worry I'll remind you'.....My second was my boy Davy who my daughter was quick to help write his letters, and he'd draw pictures emphasizing his point. Obviously Santa's prying eyes were constantly on their minds. So my being creeped out by an Elf or Reindeer was not necessary.
