This study was designed to examine the possible connection between a child’s gender nonconformity and attitudes toward both the child and the mother of the gender nonconforming child. Specifically, this study explored the impact of gender nonconforming behavior on undergraduate student perceptions of the child and the parenting competence of the mother. Following social psychology theories examining stigma and stigma by association, this study represents an attempt to determine whether gender nonconforming behavior is a stigmatizing factor, and if that stigma is carried over to the mother. Findings from this study suggested that gender nonconforming behavior is indeed a stigma for children, and mothers of those children are at risk for stigma by association
