This article takes up a question of how early childhood studies and kinesiology might undertake interdisciplinarity together. Working with the provocation of the phrase 'movement belongs to all of us', this article probes the character of three particular interdisciplinary alliances between early childhood studies and kinesiology, asking what becomes possible and impossible for interdisciplinary work amid each collision. These intersections include moving with humans and new materialist movements, dancing childhoods and bodily boundaries, and doing collaboratories and social justice. Working closely with each of these intersections, I propose discord, perceptibility, and collectivity as three possible practices toward inventing unfamiliar interdisciplinarity between early childhood studies and kinesiology.
