Parenting for Primates

This is the name of a book by Harriet J. Smith, published in 2006. The title means: "buy me". I can't imagine a life worth living without such a book in my bookshelf.

Harry Harlow experimented with infant monkeys, giving them the choice between a wire milk-giving dummy mother and a fuzzy fur dry one. The infants preferred the latter.

Dario is even smarter: Often, he prefers the fuzzy milk-giving mother to the fuzzy dry father. Despite the songs.
