The Phenomena of Early Development

[Columbus, Ohio]: Ross Laboratories, 1959. Very good to near-fine.. A detailed guide for new parents offering insight into child development and psychology. The booklet marks expected milestones, sometimes down to the week, between the baby's birth and the twenty-four month mark, giving a view into how an infant grows into a toddler. Covers physical changes (e.g. when the baby begins to roll over or crawl) as well as social and psychological changes (e.g. when they may respond to games like peek-a-boo, or initiate social contact by smiling). Single vol. (8.5" by 5.5"), pp. [36], photo illustrated, stapled in original illus. wrps. with illustration of a young child's profile. Offered here with the original accompanying five (5) at-a-glance schedule cards for babies aged five weeks through two years, measuring approx. 8.5" by 5.5", and one (1) printed leaf of "Instructions for the Newborn" with direct advice for bath time, feedings, and nutrition for the post-partum mother (8.25" by 5.5"). Ross Laboratories was founded in 1903, and produced infant formula from 1925; it would later be mass-produced as "Similac" infant formula.
