I agree with you. Kids aren't allowed to fail anymore. And as a parent, when I try to let my kid fail, I get scolded for being a bad parent. Broken bones used to be a right of passage for kids. Now it happens far less. While a broken bone sucks, it teaches you important lessons! Don't do that again, and hey, you messed up but you're fine now.

I feel like painfully falling without breaking bones are pretty good lessons already, and I don't quite see what the broken bones add there.
