If you have kids, or ever spent an extended period of time looking after them, you know how exhausting they can be. There are moments when you just wish they would finally lay down and take a nap so you can have some time to yourself.
Whether it's to do a quick workout in the living room, make yourself an actual lunch, or watch something on Netflix that isn't Trolls: The Beat Goes On or Boss Baby, a solid hour and a half nap for a kid can do wonders for their temperament for the rest of the day and your own sanity.
The thing about kids though, is that they don't really care so much about your plans. They're going to do whatever they want to do, whenever they want to do it, and they'll fight for it tooth and nail. For some reason, sleepy-time is a kid's natural enemy.
