Specific suggestions are offered for mother-infant activities, sequenced according to developmental levels, which foster the physical and mental development of the infant and the socio-emotional relationship between mother and infant. The activities are intended for use by professionals, paraprofessionals, and mother-teacher aides who work with infants in Day Care and Home Bound programs. The program is based on the Uzgiris-Hunt Ordinal Scales of Infant Development and includes these activity categories: (1) Object Permanence, (2) Development of Means, (3) Imitation (Vocal and Gestural), (4) Operational Causality, (5) Object Relations in Space, and (6) Development of Schemas. A list is given of toys and other materials suitable for inclusion in a mother-infant game kit. (NH)
