   For Harper, on Her Arrival
   
   Hear the small breath she brings into the room,
   A fist curled tight around her mother's finger,
   Rose-pink and new, wrapped in a knitted bloom
   Pinned with a ribbon, stitched by a proud knitter.
   Every grandmother has already claimed her nose,
   Her eyes, the curl that hides beneath her cap—
   Rest now, little Harper, while we hover,
   Safe in the cradle of our laps.

   river your name runs on, Harper, carrying you.
