Dad watches his baby girl learn to roll, learn to push herself up, then learn to crawl.
Now she can find out what’s over there. That shape. That shadow. That thing.
Wriggling across the wooden floor, she reaches with her pudgy hand and grabs the squishy ball. Giggling with satisfaction, she tries to eat it.
Only a few years later, his little girl asks endlessly, “What does this do? How does that work? What if houses didn’t exist?”
Answering becomes more difficult, but dad keeps trying because he remembers how curiosity encouraged her to learn and the giggle it produced.
