Mother-infant interactions were filmed at 5 and 13 months of age during naralistic play situations at home. Questionnaire data were also collected. Resuts revealed that both matemal didactic and social interactions decreased over the 5 to 13 month time period but(only for ifants) objec-oriened interaction increased over time. Infant objec-oriented interaction at 13 months was predicted by cumulaive efects of both mother s social stimulation at 5 months and infant social interaction at 13 months. Infant's social interaction at 13 months was predicted by infant's objec-oriented interaction at 13 months. Infant language developrment was predicted by mother's didactic stimulation..
