I will admit that even with a later-in-life-only-child-made-by-science, I kind of sporfled at the "complete shell of himself" by being 30 minutes late on his nap. It's not like kids have little atomic clocks in their cribs. There's setting a schedule and there's thinking a kid's whole world was rocked for three days by one slightly late nap.

Don't get me wrong: grandma was clearly out of line, and should not be entrusted with the kid's sole care again, at least for a while. And it sounds like she is herself a terrible parent. But there were a lot of things in how LW described the incident, starting with "spunky" and ending with the way LW framed the day as graciously allowing the grandparents to spend time with their grandson as opposed to them doing her the favor of babysitting that doesn't quite settle for me.
