This paper reports on the development and use of several tools designed to sensitize caregivers to the fact that infants are very different from one another and that caregiving needs to be tailored to the styles and needs of each child. Four approaches were used: (1) having caregivers rate the infants regularly on a small number of rating scales (which the caregivers themselves helped to develop), graphing these ratings bi-weekly and using them in regular staff discussions of the infants. Dimensions covered in the scales were affectivity, persistence, level of attention, sensitivity, activity, quieting and consolability, and initiation of exploration; (2) having caregivers develop and keep up-to-date a checklist charting each infant's progress in reaching various typical developmental landmarks (listed under five general headings: gross motor, manipulative, perceptual-cognitive, language and social); (3) having caregiver present during intermittent developmental testing of infants she cares for followed by discussion with program director; (4) making selected observations of particular infants and their environmental experience and using these as a basis for discussion with the caregiving staff. Appendices include the scales for rating infant characteristics, rating sheets, and checklist of developmental landmarks. (MS)
