Building more on these comments that parents should be more careful with their children etc etc.
Children LEARN by failing. They cannot walk without falling. They cannot ride bikes without crashing. They cannot climb trees without falling. They cannot learn how to go barefooted unless they do. they cannot draw unless allowed to draw, paint unless allowed to paint and feed crocodiles without learning how to feed them
Seriously, as a parent its a very tough thing to do - letting your child fail. But they're BETTER for it, not worse, in the long run.
Overprotective parents don't get that, they don't see it nor do they understand it. And its sad.
