When They Can't Tell You What Hurts is a practical, respectful guide for parents and caregivers of children who do not use words to communicate. It addresses the 2 a.m. uncertainty of not knowing whether a cry, a refusal, or a new habit means pain, fear, or something else. Without offering diagnoses, cures, or medical advice, it shows how to build a baseline, observe systematically, track patterns, use simple tools, and communicate findings to clinicians so that the child receives appropriate assessment and care. The book treats the child as a person to be understood, not a problem to be fixed, and treats the caregiver with honesty about the limits of what can be known.
