Cross-system collaborations are central to the provision of services for young children with disabilities who have experienced abuse. While multiple position papers and policy briefs emphasize and encourage these cross-system collaborations between the Early Intervention and Child Welfare systems, very limited empirical research has examined these collaborations. This intrinsic case study examines Jocelin, a young child who experienced abuse, her family, and the EI and CW professionals who support her and her family. We share three case study 'patches' to examine the approach to, as well as the quality and quantity of EI and CW services provided to Jocelin and her family. Implications for future research are discussed.
