And while one dad took it upon himself to dress up as a human elf, we've found another family that might have just topped it.
Alan Lawrence, a dad from Utah who runs That Dad Blog, decided to turn his own four-month-old son Rockwell into an elf.
"All of our friends do 'elf on the shelf' and I've always thought it was sort of creepy, but sort of fun - this idea of an elf coming to live in your home and moving around to different places," Lawrence told TODAY.
"And I'm like, what if it was a real elf? And of course, being parents, we already have the cutest little four-month-old. So we decided to make a fun series."
Lawrence, who is an art director, has been recording daily pictures of his elf named Rockwell on his blog and Instagram account.
Although it looks like his four-month-old son is sometimes sitting in daring positions, Lawrence has superimposed his son on the more risky photos.
So far, Rockwell has been caught putting cookies into the video player, drinking syrup and wrapping toilet paper round the Christmas tree.
Lawrence has added his own comical story each day with Rockwell the elf.
"Day 1: We woke up this morning to find and elf in our family room," he wrote on 1 December. "Our neighbours seem to think he is part of the 'elf on the shelf' tradition but we are still not sure.
"He doesn’t talk much, just sits around watching us and eats all of our food."
Lawrence said he is "thrilled" with the reaction to this project.
He added: "It's funny because I thought, I'm sure someone has done this before.
"But everyone is responding and mentioning a friend to say, 'Hey, you should do this with Sally!' or talking about doing it with their own kids."
See some of Lawrence's brilliant creations with Rockwell the elf below.
"I made pancakes this morning but we had to eat them without syrup because he wouldn't let us touch it - just sat on our bananas and watched us eat."
"Okay this elf needs to go back to the Candy Cane forest or wherever he came from. Today was the second day Will misses his nap because this elf woke him up to tell him Narwhal jokes."
"I could totally let you drive Santa's sleigh, I do it all of the time."
"Third time telling this elf not to put cookies in the VCR! He is fascinated with jamming them in there."
"The elf has been a huge help wrapping gifts this week, but I was not as grateful when I stumbled to the bathroom in the middle of the night and found this present."
"Flipped on the lights and caught him red handed. Somebody needs to start earning his keep around here."
"So I ended up taking all of the syrup and candy canes out of our house hoping this elf would leave but it only made things worse."
"The elf wouldn't stop bragging about beating Godzilla at every game we own."
"This time the elf has gone too far. Tonight he waited until I hand my eyes closed washing my face in the shower, then snuck up and started signing "Joy to the World" at the top of his lungs."
