Participants will be able to: 1. Explain how sensory systems (including interoception, touch, and movement) influence emotional regulation within play and play therapy processes. 2. Apply play therapy interventions that support children’s sensory awareness and co-regulation to enhance emotional regulation. 3. Integrate a play therapy-informed parenting lens by coaching caregivers to support sensory-based regulation through play and everyday interactions. Description This training explores how the sensory system serves as a foundational pathway for emotional regulation in typical child development, with direct application to play therapy practice. Rather than viewing sensory differences as problems to eliminate, participants will learn to conceptualize sensory experiences as meaningful signals that inform a child’s internal state, relational needs, and regulatory capacity. Grounded in current research on interoception, affective touch, and sensory-motor development, this training highlights how children develop emotional regulation through embodied experiences—particularly through co-regulation within relationships and play. From a Synergetic Play Therapy–informed lens, clinicians will explore how the therapist’s own nervous system, presence, and attunement interact with the child’s sensory experiences to support regulation. Participants will learn how to assess for sensory contributions to dysregulation, differentiate when sensory experiences are adaptive versus when they are contributing to overwhelm, and respond in ways that support integration rather than suppression. The training also incorporates a parenting lens, equipping clinicians to help caregivers understand their child’s sensory world and respond in ways that foster regulation, connection, and resilience. Emphasis is placed on translating play therapy concepts into accessible, relational strategies parents can use in everyday life. By the end of this training, participants will be able to connect sensory processing, emotional regulation, and relational safety into a cohesive, developmentally aligned framework that enhances both play therapy effectiveness and caregiver support.
