I wrote that years ago. I would like to soften it. "Don't yet" isn't as nice (or as true) as "might someday."
They did all learn to read, and I was confident that they would. But spinach, mushrooms and green chile might not be anyone's eventual go-to foods. It can seem to be pressure to say "Someday you will" about some things, but "someday you might" makes sense.
