The goals of this study were two-folded: (1) to examine the effectiveness of student-led teacher research as a vehicle for strengthening preservice teachers' preparation to form relationships with the families of infants and toddlers and (2) to enhance preservice teachers' sense of professionalism and commitment to the field of early childhood education. Results suggested that the students experienced both personal and professional growth during the course of this teacher research project. Students reported gaining new insights about parent-provider relationships in infant care, strengthening interpersonal communication skills, and constructing a greater sense of professionalism, advocacy, and allegiance to the early childhood field.
