Yesterday was a good day. Not the day off I pictured when I took this job (it isn’t an actual day off, but we pretend), but a good day.

When I signed on as the primary caretaker for my granddaughter, the wins were simple. Bottle finished. Burp achieved. Dry diaper confirmed. The job description fit on an index card.

It doesn’t anymore.

Now, a good day means I kept her entertained long enough that she went down for her nap without excessive drama. It means everything ran on something resembling a schedule, because the adults in her life are trying very hard to pretend their lives aren’t a complete shipwreck since she arrived. It means I successfully assessed which objects on her high chair tray were unlikely to choke her, a calculation made more interesting by the fact that God has not yet seen fit to give her teeth.

The surveillance portion of the day is non-negotiable. We walk laps — kitchen, living room, hallway, back to kitchen — while she conducts a thorough inspection of everything that has changed since her last walk. Usually, nothing has changed. She checks anyway.

Outside, it’s the mulch. The brown mulch in the flower beds has captivated her in a way I cannot fully explain. It fits perfectly in her little fists. Also in her mouth, which is where most things end up. Her appetite operates on one schedule: eyes open.

A good day also means I timed the diaper change correctly. Change her, set her down in the living room, execute the strategic maneuver of leaving the bathroom door open, and move with purpose. If the math works out, I’m washing my hands when her little crawling body appears around the door frame, just making sure I’m not having an adventure without her.

Then there are the moments that have nothing to do with logistics.

The reluctant laugh — the one where her tummy figures out she’s ticklish before she’s fully committed to the idea. The way she sticks her chest out when you hold her hands, and she leads you, with great authority, to all the important places that require daily review. The diaper bag left unzipped for thirty seconds, which is thirty seconds too long, and the full excavation that follows. She’s looking for something. We don’t know what. It goes in her mouth.

She has also discovered my glasses. There is a game now — I didn’t name it, she invented it — where she removes them from my face with the focused determination of someone defusing a bomb. I’m usually holding her because she’s in a pre-nap mood, which means I’m also the only available entertainment. The lenses are a mess. It’s fine.

There’s also the nap itself, which raises its own question: when she wakes up crying after forty minutes, is she actually awake, or just passing through? The answer determines whether I have time to start dinner. I have not yet developed a reliable system.

The job description has changed, but so have the fringe benefits. She has a personality that walks into a room before she does. The diapers are worse, the opinions are louder, and she has a will that I respect even when it is aimed directly at me.

But I get to watch a little human discover herself. Every lap around the kitchen, every fistful of mulch, every reluctant laugh — she’s figuring out what the world is.

She’s not the only one.
