In this study, we aimed to explore and describe the experiences of parents whose children have been diagnosed with type 1 diabetes (T1D) and the transitions of daily life. T1D is a long-term illness, and parents of children with T1D often become informal caregivers and face many challenges in their daily lives. A qualitative study design, in line with interpretive description, was used, and a sample of 10 parents of children with T1D participated in individual interviews. The COnsolidated criteria for REporting Qualitative Research (COREQ) checklist was used. The interviews were analyzed using interpretive descriptions. The analysis resulted in one main theme: “The realization of having taken ‘daily life’ for granted and having to accept a new reality,” with six themes showing different transitions in the parents' daily lives, including transitions in daily life patterns, parenthood, in relationships with family and friends, relationships with school personnel, relationships with healthcare personnel, and in knowledge and learning about the illness. Parents experienced multifaceted changes that affected their lives, as shown by the six identified transitions. Being the parent of a child with T1D implies a new reality with complex, irreversible life changes that may be unknown and unspoken to healthcare professionals and society. Healthcare systems, school personnel, and society at large need to improve their knowledge regarding parents' situations to better support them in embracing a new reality for themselves and their children long after the onset of T1D.
