Consensual non-monogamy (CNM) is a concept that encompasses all forms of intimate relationships in which partners allow themselves, in full transparency, to engage in sexual and/or romantic relationships beyond the traditional dyadic couple. To date, little research has been devoted to the family in this non-traditional context. Based on 34 semi-structured interviews with Canadian parents in polyamorous or open relationships, we explore in this article how they combine CNM and family. Specifically, we examine the reasons behind parents’ choice to inform (or not) their children of their relationship type and to integrate their intimate partners into their family life. Interviews highlight four key themes influencing parents’ coming out to their children : 1) social/legal recognition of relationship/family diversity ; 2) children’s (in)ability to understand issues related to sexuality and intimate relationships ; 3) parent’s (un)certainty about their intimate relationship choices ; and 4) perceived limits or benefits of the nuclear family.
