Then the kids get potty trained and it’s like the sun comes out from behind a poop cloud

I was astonished at the extent to which popular culture lied to me about diaper changing. Every TV or movie depiction of a man dealing with a baby includes him absolutely losing his goddamn mind over how difficult and gross diaper changing is. From fiction, you'd have thought that changing diapers was as difficult as gathering honey from a wasp's nest. In reality, I adjusted to that in less than a couple of weeks.

Now the fact that babies and toddlers can get so tired that they can't go to sleep, that was an unpleasant and unexpected revelation.
