This study examined how parents of children with developmental disabilities can function, exploring how parents' experiences of reading and creatively engaging with their children's drawings can shape their roles and meaning. For this purpose, a case study was conducted with four parents who participated in an art education program for adolescents with developmental disabilities. The findings revealed that in their mediating role, parents functioned as interpreters, sensorially translating their children's artistic expressions and interpreting them based on experience. They also emerged as intermediaries, serving as relational conduits within the ‘space’ where emotions, experiences, and meanings are exchanged, and also bridging their children's art and society. These findings demonstrate the need for disability arts discourse to expand into relational and social contexts. Simultaneously, they suggest the necessity of establishing institutional foundations and support systems to enable parents of children with developmental disabilities to grow into professional mediators.
