What We Missed

The Untold Story of How We Eat, Sleep, and Breath

by Yuvan Rasiah

Before we learn to walk or speak, we learn to breathe, sleep, and eat—the foundations of being human. These are the quiet miracles that sustain life. But what happens when those foundations falter?

Blending vivid storytelling with evidence-informed, scientific perspectives, What We Missed traces how birth, restricted fascia, and disrupted breathing patterns can silently shape a child’s development—impacting digestion, sleep, speech, posture, and emotional regulation. What starts as a subtle difficulty nursing or breathing can echo across a lifetime, influencing everything from attention and growth to confidence and connection. Through the experiences of the author and five other families across continents, the book highlights the subtle, often overlooked signs of oral and airway dysfunction—and the long road to understanding them. Their journeys of perseverance and hope are interwoven with insights from leading experts who are reshaping how medicine, dentistry, and therapy intersect.

What We Missed features insights from a diverse group of pioneering medical and research professionals from Harvard and MIT, leaders whose research and clinical work span across biological dentistry, neurology, sleep science, airway health, and public health. Their perspectives are by experts in epigenetics, biomechanics, chiropractics, birth and infant nursing, occupational therapy, and growth-centered orthodontics. Together, they represent a revised, integrated approach to understanding the human body, one that brings together medicine, movement, and the anatomy of breathing, chewing, and sleeping. These voices form a holistic narrative that transcends siloed disciplines.

What We Missed invites readers to connect the dots between symptoms too frequently considered as unrelated, such as reflux, fatigue, anxiety, speech delay, or poor sleep, and see the child as an integrated system, guided by fascia, the vagus nerve, and breath. While the book is grounded in real science and case studies, it is not a diagnostics manual or a research document. It is a call to empathy and awareness. It celebrates the parents who refused to accept “It’s normal,” the clinicians who listened differently, and the children whose healing illuminated new pathways of understanding.

By sharing what we missed, we hope to give other families a clearer path—and invite you to explore nuances that often go unseen—because every child deserves to breathe deeply, sleep soundly, and eat without pain.
