Research on children of persons with a severe mental illness focuses predominantly on parents' and others' perceptions. Children of mentally ill parents form a vulnerable group that has not been adequately paid attention to in psychiatric care institutions. Comparatively little is known about the children's recognition of their parents and the everyday situation of these families. The aim of the study was to investigate experiences of their life situation in children 10-18 years of age in a family with a parent with a severe mental illness. Eight children were interviewed concerning their everyday life situation. The interviews were analysed inspired from using thematic analysis. From the analysis of the material emerged aspects concerning the following themes: need for conversation, love for their family, maturity, experience of fear and blame, feelings of loneliness, responsibility and associated stigma. This study highlights the situation experienced by children of severely mentally ill persons who also are parents. The study may be found to be a basis for inspiring structured interventions and treatments programmes including children of the adult patients seeking psychiatric treatment.
