TPP 488: OT Kathryn Hamlin-Pacheco on Tactile Defensiveness & the Nervous System

Today’s episode is a deep dive into tactile defensiveness and sensory distress, especially around clothing. My guest is Kathryn Hamlin-Pacheco, an occupational therapist who helps kids and families understand their brains and bodies through everyday neuroscience. Kathryn will break down what’s actually happening in the brain and nervous system when children experience tactile defensiveness, and why clothing can feel so overwhelming for some kids. We talk about the role of co-regulation, how parents can help create positive associations with getting dressed, and practical strategies for supporting children in navigating their sensory experiences with more safety and less stress. This episode is a grounding, compassionate look at sensory processing—and a reminder that when we understand what’s underneath the behavior, everything shifts.
