This paper presents findings from recent Australian qualitative research with lesbian co-parents where study participants' fluid narrative identities are deconstructed in order to better understand how language constructs relationships within private and public domains. Language used to define, describe and give meaning to roles and relationships of lesbian co-parents within social and kinship networks and wider community is explored. Through claiming language and telling their stories lesbian co-parents give meaning to their lives; affirm their identity; and present their relationships as visible and valid.
