Long stretches? Try parenting full time. Those are long stretches. Birth until they leave for university.
I've always been impressed by parenting. These have been trial by fire for me as I know/knew very, very little about small kids. So far, they're properly dressed, fed, and loved on; that's the best I've got. I was really just being silly and making fun of myself. All parents know kids are work; I had been clueless mainly, so I poke fun at my own ignorance.
