IntroductionParents of persons with profound intellectual and multiple disabilities (PIMD) play a major and often lifelong role in the care and support of their child. A better understanding of parents' perspectives regarding their experiences of parenting their child with PIMD is essential to support them more effectively. Although this topic has been explored extensively in Anglo‐Saxon and Northern European countries, little is known about the experience of these parents in a highly institutionalized context such as that in France.ObjectiveWe explored parents' experiences of the activities they performed to care for their child with PIMD (namely, the ‘parenting work’) in the French context.MethodQualitative semistructured interviews were conducted by telephone with 34 parents of persons with PIMD aged 8–35. The resulting data were analyzed using thematic analysis.ResultsThe analysis highlighted the diversity of activities performed by parents as well as the influence of context on the forms of this parenting work. Five themes were developed: (1) navigating the challenges of obtaining medical recognition; (2) negotiating a concealed domain and becoming an expert; (3) unfolding medical and medicosocial care management; (4) navigating the challenges of daily living and (5) shaping one's child's possibilities.ConclusionThis study offers a better understanding of the challenges, levers and expectations of parents of children with PIMD in France. Contextual factors such as the lack of knowledge of PIMD among health professionals, access to knowledge and know‐how associated with care management, the administrative complexity of access to care and equipment, institutional issues (e.g., professional turnover) and societal ableism (e.g., access to infrastructures, interpersonal discrimination) shape the work parents perform to support their child's needs. It is necessary to consider contextual aspects to better support these parents and their children. Suggestions for applications are provided in the discussion.Patient or Public ContributionOne of the researchers, a parent of a child with PIMD, supported the research design and provided feedback on the study's procedures and manuscript.
