The paper deals with the issue of supporting inclusion through early therapeutic-pedagogical stimulation using Marie Montessori’s concept. It presents the results of qualitative research, on the basis of which the therapeutic strategies of the therapeutic pedagogue were identified in the context of early stimulation. The research presents verbal and combined verbal-physical-activity strategies in early therapeutic-pedagogical stimulation according to M. Montessori. Therapeutic-pedagogical early stimulation according to Maria Montessori’s concept is a specific therapeutic approach within a broader understanding of early intervention. The goal is to maximize the participation of a child with at-risk development in the life of the family and community in the context of supporting inclusion.
