I think it would be a really amazing experience, but I would be bummed out to find that my favorite childhood memory wasn’t real.
Don't agree at all. Do you feel betrayed that Santa is not real or there is no such thing as a tooth fairy?
I really don't understand the urge to lie to your children because your parents lied to you.
Which is better, telling your child:
"yeah you will lose all your baby teeth and each one will hurt and bleed and make you look silly with big gaps in your mouth"
or
"oooh you lost a tooth, now let's put it under your pillow and the tooth fairy will exchange it for a little gift while you sleep"
You have a wide variety of choices as to what to tell your child that doesn't include lieing. You can celebrate the loss of a tooth as a positive step of growing up without telling a lie about a creepy fairy that sneeks into houses and collects teeth.
Adults may rationalize to themselves that they lie to children to protect the children, but I think it is often more motivated by the adults' desire to avoid having an uncomfortable and difficult conversation.
Memories are real, experiences are as real as one wants them to be.
We all learn critical thinking and separating fact from fiction eventually, but that doesn’t mean you can’t look back fondly on experiences you enjoyed as a kid.
