How Do other Mammals Nurse?

Days and nights we stayed up in the bracken pile, curled around one another, while I gave suck and licked and settled squabbles. They fed and slept and fed and squabbled, and I watched their small, sleek bodies plumping up with milk. Their eyes were shut, their small heads pushed into my flank, muzzles butting, jaws working hard in the rhythm of life, which is, at first, no more than suck and swallow.
