I’ve told my sons’ story before on this forum. He believed in Santa Claus. He knew the “guy at the store” was not the REAL Santa – the REAL Santa lived at the North Pole, etc. etc. My son quickly came to the conclusion on his own that I was one of Santa’s Helpers and after he fell asleep at night, mom went to the North Pole to work (remember, I am a dwarf so, I kinda fit the visual image).
Yes, I kept some presents held back that “appeared” under the tree on Christmas morning (or the morning before we traveled to grandma’s)… I had a co-worker (she had amazing penmanship) answer his letters to Santa.
Because his mom was moonlighting for Santa, DS held on to his fantasy a bit longer than most kids. In kindergarten and 1st grade, he would be patronizing to the kids who said there was no Santa – since he was felt he had the “inside scoop”.
When DS was in 2nd grade, we sat outside the Church in the car, he was going for Pageant rehearsal (he was a wise man). He looked at me and said “mom, Santa is not an actual person – is he?” I answered “No”. DS said “Okay” – went into practice and never batted an eye.
Today, that son is 15 and towers over me. He has a vibrant imagination, writes some pretty good fiction, and reads like a fiend. I can stand here and tell you that believing in Santa did nothing to harm is faith in his parents or his Lord.
BTW – maybe the OP’s memory is playing some tricks - I cannot imagine any parent letting a child cry for 8 hours! I cannot imagine a child being physically able to cry for 8 hours…
