My first manager at Google (and the first in my career) had 2 young kids, around 5 and 7 respectively.
He left the office every day at 6:30 sharp and, like clockwork, would answer emails and code reviews starting at 10. Eventually we learned to time our emails and code reviews according to this clock.
The consistency of the timing was remarkable; our favorite theory was that was his kid's bedtime. I guess in effect, he was putting two sets of kids to bed each night :).
If they're like my kids (6, 2, and 2): 10 isn't their bedtime...it's when I've finished dinner cleanup after their bedtime and can get on my computer to finish up tasks for the day.
My 2 year old is usually sound asleep by 9, and after some cleanup I have some free hours to catch up on work. Sometimes I can't help it if it's something interesting, and makes me feel better about only spending some 7-8 hours at the office. I escaped from academia too, where I got to having anxiety about every single minute not spent working, and now am still feeling the aftereffects.
