ELI5:how can babies scream and shout so long without damaging their vocal chords etc.?

Evolution.


The babies who didn't cry when they were hungry or cold or in pain, or were unable to cry long enough to get help died and their weak vocal chords died with them.  It's also why a baby crying is one of the most annoying sounds imaginable - a baby whose cries were soothing would not wake its parents and it would not get the help it needs.
