I can understand basic safety precautions...shortly after I left elementary school, they replaced the bed of really small rocks they had around their various sets of playground equipment with thick, bouncy rubber matting. I can attest that those fucking rocks were anything but soft or safe, so can the small bald spot on my head where the staples went after I split it open like a head of lettuce. Twice.
But, yeah, this whole overprotective super-nanny bullshit's really gotta stop. Kids are gonna get injured, kids are gonna get hurt, its part of life. Teach your kid to be safe and clean, sure, but at the end of the day, you shouldn't take away your kid's bike just because he fell off it and got bloodied up a little. Give the kid some kiddie Tylenol, a bandage, and some Neosporin, and let him at it again when he feels up to it. The only way you truly get good at something is to fail, and fail a lot. I learned that with basic social interaction...and mine was not because of the overzealous helicopter parent bullshit, but because my dad drilled the idea that everyone was evil and untrustworthy into my head when I was but a boy, and that kinda shit's hard to break free from.
I still have a hard time trusting people, interaction's easier thanks to medication and a lot of hard work...both on my end and from the best girlfriend in the whole world, but I wouldn't call it easy, just yet.
The problem really isn't with parents and adults in general worrying about kids, we all worry about kids (ours or not), its part of being human, the problem lies with passing that worry on to the children in question. They shouldn't have to worry, because, and I can attest to this personally, it will rob them of their childhood. I didn't get to have one, because of the aforementioned paternal conditioning and because my family is a hotbed of mental illness. My childhood was taken from me, and there's nothing I can do to get it back, no matter how much I wish I could...I don't want that to happen to anyone else.
