 Nevertheless, philosophers and bioethicists have tended to look skeptically on the possibility that a person with a disability could offer the mutuality and equality required for a satisfying relationship with a nondisabled friend, romantic partner, or family member. Even in those relationships where unequal contributions and asymmetric dependence are the norm, as with parents and their children, a child’s disability has been seen as an obstacle to a desirable and rewarding relationship. The disability is perceived as creating an uncomfortable degree of inequality and dissimilarity; parents have difficulty picturing the child growing into a productive adult and parent, fulfilling some of the goals people have for undertaking childrearing (Ruddick 1998). Additionally, the child’s disability has been viewed as imposing burdens on parents that differ from and greatly exceed those posed by raising children who do not have disabilities (Botkin 1995). Moreover, the child’s disability is presumed to extend the duration of parental care (Botkin 1995; Kittay 1999; Lindemann and Nelson 2008). Similarly, when the bioethics literature considers people with disabilities as parents, it is largely to assess whether it will be harmful for children to be raised by disabled parents (Coleman 2002; Robertson 2004); or whether adult children will have to give up their other life projects to care for their newly-disabled parents (Callahan 1988).
