Advocating for a child's rights and needs is an experience shared by most families of children with autism spectrum disorder (ASD). This qualitative study is an in-depth secondary content analysis of the discourse of 13 immigrant families on their advocacy experience during the early childhood period. Results revealed that, from very early on, parents engage in an adaptive process as advocates to ensure an inclusive future for their children and call on support during key transition periods. In light of these findings, from immigrant families in a Canadian province, implications for practice, policy and research are discussed.
