This article describes and reflects on the first six meetings of a newly established Autistic community council, founded to steer a participatory, longitudinal qualitative study investigating the reproductive health of Autistic people with wombs. The two key aims of these initial six meetings -- involving four Autistic community leader members and three Autistic researchers -- was to (1) guide the start of the project and the development of accessible recruitment materials for the future eight lay members and (2) establish a safe space and a model of accessible communication. We draw on extracts from transcripts made during meetings, member 'field' notes and a reflexive co-writing practice to identify the ways in which a sense of safety was built during these first community council meetings. We explore what it means to be an "insider"-only Community Partnered Participatory Research Council and reflect on the praxis we developed to facilitate Autistic knowledge production.
