I always had a philosophy about that. Stop doing the elf on shelf thing and it will fade completely out of sight. I was fortunate that it wasn't around until after my kids and grown up, but, even they took the page from good old Dad's playbook and never did it with their kids. There is enough to do this time of year without adding to it.
I'm not sure how we used to survive and have wonderful memories about Christmas without that stuff. We had simple stuff like letters to Santa read on the radio by Santa himself. My sister and I used to sit every night glued to the radio to hear our letters read by the big man. We did have the religious observations of Advent and Advent Calendars, carols and visiting the elderly in homes and hospitals, Midnight Mass (my Dad sang in the choir). There were Christmas trees (real), the smell of pine, tinsel on the tree, one present allowed to be opened on Christmas Eve. (always regretted that because that meant one less on Christmas Day), laying on the floor below the Tree and looking at our reflection in the ornaments, bubble lights, Homemade Christmas ornaments, gifts laying in wait under the tree with room left for Santa's stuff. Cookies and milk plus a carrot left for Santa and the Reindeer.
Panicking when there was no snow on the ground on Christmas Eve, filled with anxiety concerning how a sleigh would land without snow. (Dad told us that Santa had tires that he could lower to land if there was no snow. We bought it just like we bought the no fireplace thing. They left the door unlocked.) All good memories that don't seem to be used much anymore. Some yes, but, not many, instead you have an Elf on a Shelf.
