This manual, which discusses materials that promote infant growth and development, is part of an approach to working with low-income mothers and infants in their homes to increase the educability of the infants. There is a brief discussion of infant development and the Demonstration and Research Center for Early Education Infant Study (DARCEE) Skill Development Curriculum Model, and a section on provisions recommended to promote infant development; provisions by the mother; and provisions of play materials for infants. Another section is devoted to materials field-tested in homes. Materials used in the DARCEE Home Visiting Program are described, including materials distributed by the home visitor, assignments made by the home visitors, verbal motivators given by the mothers, and home visit illustrations.
