If we can't tell kids Santa, is real...
Then we can't tell them to believe in fairy tales, Tinkerbell, princes and castles, imaginary friends, magical lands...or just about anything they read in a book.
I think I want my kid to be allowed an imagination. To dream about magical things. To marvel, at life and have wonder. Too soon, the world be very real to him and these things will just be a memory.
Kids grow out of Santa. Everyone I've known says they just grew up and knew it wasn't real. I've never met an adult, that is haunted by finding out about Santa. Santa is NOT harmful. I think parents are uptight about this and segregate their kids from enjoying, what other children enjoy.
