Little previous research has elucidated the everyday experiences of autistic girls or their families. This study used qualitative in-depth interviews to explore mothers' experiences of the diagnosis, presentation and impact of caring for a daughter with autism. Nineteen women with autistic daughters (aged between 7 and 18) participated in the research, which took place in Ireland. Thematic analysis identified six themes: What's Going On?; Road to Acceptance; Beyond the Stigma of Autism; Autism: Like a Girl; Mothers Holding It All Together; and Mothers Roll Up Their Sleeves. The analysis suggests that the path of autism in girls in Ireland is marked by diagnostic delays, social stigma, interpersonal difficulties, mental health comorbidities and parental stress. However, these challenges were offset by the resilience of mothers, buttressed by pride in their daughters and support from other women. Results will inform the development of policy and practice that is sensitive to the lived realities of autistic girls and their families.
