ELI5: Why do infants lose their minds when they're tired instead of just falling asleep?

Think how frustrated you feel when it's the middle of the night and you're nervous and can't get back to sleep.  You're kind of tired, but you can't shut off the anxious thoughts.

Focusing on going to sleep is a skill that has to be learned.  You can *make* any baby go to sleep, but the trick is to have them "choose" to do it.  If they aren't taught the skill of going to sleep, they won't know how to do it.
