The quality of life of autistic children and their parents is impacted by the stress they experience, their coping strategies and the availability of professional health, social and educational support services. Recent changes in the structural organisation of child disability professional supports in Ireland mean that in-depth knowledge about current experiences of parenting autistic children is necessary. This qualitative study explored parents' perceptions and experiences regarding their challenges, stress levels, coping strategies and professional support services. Semi-structured in-depth interviews were conducted with six parents of autistic children aged 4 to 16 years. Thematic analysis identified three core themes: 'The Autism Journey: Challenges and Rewards', 'Navigating a Flawed Support System' and 'The Importance of Social and Professional Supports'. Findings emphasised that parents face endless challenges in caring for autistic children. Dealing with autism-based support services, however, is the greatest stressor experienced by parents. It revealed that the system to access services is experienced as difficult and parents consider it is operating inadequately. This reveals a pressing need to improve systems that provide professional support services to autistic children and their families.
