In my 7-month-old, who's now learning to stand. Grab someone, pull myself up. Wobble wobble. Again. And again. And again.
In my 2.5-year-old, who asks for the same story over and over, even when we can both remember the lines. He recites them with such glee.
But in grown-ups? It's once and done. Unless it's a productivity hack. A favourite song. Or a necessity for life.
Perhaps no repetitions are needed, because there's not much growing left to do.
