My LO1 has always been very aware of things and intuitive.
Last year, she asked me if Santa was real and I sort of hemmed and hawed through it bc I didn't want to lie to her. This year, she flat out told me that Santa doesn't exist. She's six

I also told her not to tell other friends and her brother and keep it between us bc I don't want her to be the source of other kids unhappiness.

Just wondering when other kids found out?
