How can they trust me with a child, period?

I think I only put deoderant on my left armpit today. The right one is getting a little stinky. (It could be the blouse; not sure.) I remember finding my deoderant on the sink with the lid off and remembered at least applying it to my left armpit, and the thought was, "Would I really just apply it to one side and then pause?" so I put it away.

Things like this throw me--I can't handle my own personal hygeine, and yet, I'm in charge of another being's whole life. At least I manage to get food into him and cause him to sleep, and he usually shows up to events with clothing on. But some of the day-to-day stuff is challenging when I'm not sure if I've deoderanted my right armpit on any given day.
