“…The research conducted in Poland and elsewhere so far confirms that siblings are often expected to assume the role of primary caregivers in due course, becoming key figures in the lives of their brothers and sisters with disabilities, while embracing the responsibilities of a legal guardian and providing financial support (Bigby 1996(Bigby , 1997Freedman et al, 1997;Greenberg et al, 1999;Krause et al, 2010;_ Zyta, 2004). Relying on research performed to date, siblings are not only expected to play a guardian role; rather, there are findings demonstrating that they are, indeed, able to act in various vital life capacities for their brother and sister with a disability as far as care and support are concerned (Hall & Rossetti, 2018;Kruithof et al, 2022;Lashewicz, 2018;Lindahl et al, 2019). This readiness predominantly originates with these siblings' realization that they may one day, when their parents are no longer physically fit or are no longer alive, take full responsibility for their brother or sister and assume the duties once met by their parents (Griffiths & Unger, 1994;Heller & Kramer, 2009).…”
