If we're always protecting our kids from danger, real or imagined, if we're always shielding them from bullies and slings n arrows, and water pistols that look like guns, from violence and poverty and strangers, how will they ever learn how to handle themselves as adults?
How do they learn to distinguish real danger or violence or threats from the pretend kind? Im not saying we have to throw them out into traffic to see if they can survive, only give them the chance to make their own choices now, when the choices are still small, and their own mistakes NOW, when the mistakes are (to our eyes) minor, and know that they need to find their own levels of fear and comfort.
I dunno. It's a jungle out there, and we won't always be around to navigate it for them.
