I think its true.

I'm reading a book at the moment called How Children Learn by John Holt. The TL:DR is basically that we need to trust our kids more.

I can see the reason why parents or schools and playgrounds want to keep everything safe. Some over confident kids can just run and jump off things they shouldn't and can get hurt. Luckily for now mine are pretty cautious. Still I need to stop myself from interfering sometimes.
