What came to my mind instantly are the
Brothers Strugatzki and their story "Baby" or "Little One" which was published in the US under the telling title "Space Mowgli" in: Strugatsky, Arkady and Boris. Escape Attempt (Best of Soviet Science Fiction) translated by Roger DeGaris. New York: Macmillan Pub Co, May 14, 1982, 321 pp. ISBN 0-02-615250-9. LCCN: 82000029.
Sadly there seem to be no ebooks of this story or the other writings of the Strugatzkis available (yet).
It's the same with the works of the late Polish grandmaster of SF -
Stanislaw Lem. A real pity!
