This paper presents a bespoke postmodern reading of the corporeality and somatechnics of self and other. It situates itself within the transformative transdisciplinary space of critical disability studies. Therein, it reflects upon the speculative boundaries between self and other, in the context of childhood disability and child maltreatment. As such, how the intervals and convergent space of self and other are engendered by technologies and techniques that both safeguard and endanger disabled children, is interrogated with classic postmodern scepticism. The context is, that international evidence places the prevalence of child abuse and neglect at significantly increased levels for disabled children. This is an enduring international problem in which disabled children continue to experience rates of abuse and neglect that far surpass those for non-disabled peers. Concurrently, safeguarding efforts are undermined in ways that are grossly dissimilar to majority population peers, including significant problems in the way that disability is conceptualised and understood. Selective reading of somatic and corporeal, as well as agentic and attitudinal dimensions of the problem, hinge on the theoretical binary of self and other. The intention is to broaden the ways in which the significant problem of safeguarding of disabled children is understood. Assistive technology, surveillance techniques and temporalities, and varied relational technics of safeguarding, all help to embed a more complicated understanding of disability and child maltreatment.
