This article takes as its starting point the author’s personal experience of sudden, unexpected child death and the impetus this provided for research exploring the topic. The article charts the isolation which parents may experience following a sudden, unexpected child death and situates this within a cultural taboo around dying. The author further discusses her involvement as a researcher combining personal experience and academic study in a way which formed potentially “dangerous knowledge.” The article concludes with a discussion of how certain forms of knowledge may become segregated from research and provides ways forward from this.
