The Triple P Positive Parenting Program is a form of behavioural family intervention, and is the world’s leading parenting program ranked by the extent of the evidence base. Like narrative therapy, Triple P is practiced internationally. This paper tells the story of facilitating Group Triple P using innovative narrative practice initiatives throughout the eight-week program, ‘walking the line’ between the two practices. The paper begins with the story of how this practice innovation originated. It then describes the metaphor of walking the line before providing examples of double story development from practice. This innovation offers participants a culturally responsive and politically decolonising facilitation of Group Triple P while maintaining fidelity to the program.
