Objective: to explore the possibilities of a two-year-old boy diagnosed with motor disabilities to position itself as agent of the experience and advance within the establishment of his corporeality in a situation of being with his mother and one alone. Method: a qualitative perspective is assumed under the form of case study. A microanalysis of interactions and the deployment of child movement from ANVIL 5.0 software was conducted and his mother was interviewed. Results: it was found that despite his restrictions on movement, the child is likely to progress in his corporeality. However, the adult requires an accompaniment that fosters the recognition of these possibilities since it seems to prevail a representational gap that hinders the establishment of sensitive interactions. Conclusion: the study has implications for clinical practice in early childhood.
