Sleep hygiene is developed extremely early in life. My parents insisted that I go to bed by 8 PM until I was in 4th grade. I remember thinking how absurd it was because everyone else in my class stayed up until at least 9 PM on school nights. I might have complained about it then, but I am reaping its benefits today. Even as a grown-up who doesn't have to get to the office until 10 PM, I make sure I'm home in bed by 12:30 AM at the very latest on weeknights. Getting a good night's sleep is more important to me than basically any party or late-night social engagement, no matter how silly that may sound to those insomniacs out there. The dad in this story tried an unconventional method to instill good sleep habits in his 7-year-old, and everyone seems conflicted over whether it was smart.
