Just put every kid in a bubble, pipe in all their nutrition and mental stimulation. 100% controlled, no risks. Done right, this will also make them completely submissive gerbels for the government to control.
I have this problem with my 7 yr old daughter'* mother. She babies her over every little scratch. I got a call one day last summer after she went back to her mom'* and she was like "you have to be more careful with her" because her knee was scratched up. I was like "f*** that, she is a kid and she is gonna play and she'* gonna get hurt, that'* life."
I was hurt all the time when I was growing up, but I lived. I broke my foot once and was skateboarding 1 week later.
Kids are wusses now a days.
I say let em beat the crap out of them selves and each other and they'll be better for it when they are older.
