Stay Still so the Bunnies Will come

The Pre-K class has two soft brown bunnies in their room. They live in a bunny habitat of some sort and are gentle souls.
. . . .
In the afternoons, 4-year-olds and 5-year-olds, who in general are much too grown up to think they need a nap, do at least need a rest. Jenny has them get out their mats and lie down for a little while. Then she opens the bunny habitat and lets Olive and Ruby come out to wander around the classroom. "Stay still," she tells them, "so the bunnies can come."
. . . .
If the children lie still, the bunnies might come near them, might hop over or between their legs, might sniff or nuzzle their own soft little cheeks. But only if they lie still.
. . . .
And so they lie still, hoping that the bunnies will come. And sometimes they fall asleep.
