We have discussed the professionalism of early childhood teachers from the viewpoints of "the teacher as technical expert" and "the teacher as reflective practitioner." The purpose of this study is to examine not the technical expert nor the reflective practitioner but the emotional practices from two viewpoints: (1) Early childhood teachers' emotional practices and their relationships with young children, (2) Early childhood teachers' emotional practices and their relationships with parents and colleagues. The results of this study show early childhood teachers manage and express various emotions through not only the education and care of young children but also in building relationships with parents and communication with colleagues. Though elementary and junior high school teachers carry out emotional practices mainly in their relationships with the children, the characteristics of early childhood teachers are toward emotional practices in their relationships not only with the young children, but also with parents and colleagues.
