"This is a movement to unlock airway health from infancy — because the earliest signs of future problems often show up in how a child breathes, feeds, and functions. When we know what to look for, we can change the trajectory to help children breathe, sleep, and thrive, and grow into healthier adults."

— Dr. Shereen Lim

Why This Book Matters

Whether you’re a parent noticing subtle signs — or a professional seeing patterns across your patients — this book will help you connect the dots and take action earlier.

You’ve noticed the snoring. The open mouth. The restless sleep. The teeth grinding. Speech therapy that doesn’t seem to help. Inattention. Emotional meltdowns. Crooked teeth—but old to wait.

Maybe those signs have been dismissed—or treated in isolation. But deep down, you know there’s something more going on.

Breathe, Sleep, Thrive helps parents and professionals recognise airway dysfunction as a root cause—and how it can quietly disrupt sleep, behaviour, growth, and long-term wellbeing.

It brings clarity to what’s often missed and gives families and clinicians a shared frame work for early action—starting from birth.

Why Airway Health Matters

Airway health isn’t just about being able to breathe. It’s about how we breathe — promoting nasal breathing day and night, and supporting healthy airway development through good oral function and jaw growth from the earliest years of life.

When airway health is compromised—even subtly—it can affect sleep, focus, mood, growth, and lifelong vitality.

Airway health is the cornerstone of thriving health and well being.

And the best time to unlock it is in infancy.

Why This Book Was Written

I started out treating adult snoring and sleep apnoea — including my own husband’s. But that journey led me somewhere unexpected.

Most adult airway problems begin in childhood—and go unrecognised.

Over time, I saw the same patterns again and again:

  • Mouth breathing and snoring
  • Teeth grinding and bedwetting
  • Poor jaw development and crowded teeth
  • Feeding difficulties and early weaning
  • Oral dysfunction that went unnoticed for years
These weren’t being addressed early enough. We were missing windows of opportunity to change a child’s future.

This book brings those pieces together — so families and clinicians can act earlier, with clarity and confidence.

“A book in which parents will find much wisdom.”

“In a world where sleep problems are endemic and regarded by many as ‘normal in the trenches of parenting’, we ask ourselves; ‘does it have to be this way?’ Sleep is a fundamental pillar of health that underpins every aspect of a child’s development including executive brain function required for communication development that prepares children for life, and everything there-in. Delayed speech and language milestones may be one of the first markers parents or allied health professionals notice yet sleep screening is sadly not yet common practice. We could even say, our work as speech pathologists may be futile in the face of sleep wrecked kids and families and more poignantly true for sleep and breathing problems that may stem from poor facial development, that also impact speech! Kudos to Dr Lim in ‘Breathe Sleep Thrive’ for outlining the critical role dentists and orthodontists may play in facilitating or restoring growth of oral structures that support healthy breathing during sleep with a ‘fix before 6’ philosophy, a book in which parents will find much wisdom.”

“I wholeheartedly believe that this book will shape the way we evaluate developmental sleep issues moving forward.”

“Dr. Shereen Lim has created a ground-breaking and absolutely necessary resource on a relatively unknown but ever-present epidemic affecting our children’s breathing and sleep health. She presents an in-depth discussion on airway health – the diagnoses, treatment modalities, and outcomes for specific breathing problems – but more importantly, offers insight on underlying causes of clinical manifestations and how we can more proactively manage our kids’ health, growth, and development. Dr. Lim’s dental and sleep medicine expertise are evident in her careful explanations of the anatomic, behavioral, and functional factors related to sleep disorders, and I wholeheartedly believe that this book will shape the way we evaluate developmental sleep issues moving forward. If you are a new or experienced parent, a medical professional, or are in any way interested in population health, you owe it to yourself to read this book.”

“As restoring airway health during sleep is a gateway to wellness, Dr. Lim takes us from zero to one.” 

“Bestselling author and iconic entrepreneur Peter Thiel asks innovators this question in Zero to One: ‘What important truth do very few people agree with you on?’ Dr. Shereen Lim’s book effectively communicates her conviction in a key truth. Human health and well-being have their foundation in form and function, or anatomy and physiology. Optimizing form and function lies in interventions at key developmental milestones during a child’s growth. Missed milestones may be restorable, but the results are often imperfect. As restoring airway health during sleep is a gateway to wellness, Dr. Lim takes us from zero to one, where her inspiration comes from the integration of form and function. When you are done with this book, you will join the ever-growing community that agrees with Dr. Lim. We were just in search of a perfect voice.”

“It’s a paradigm shift moving from traditional ethos to site specific, tailored and an integrated approach…” 

“Shereen has achieved in this book what many of us in the airway field aspire to do, that is in giving a big picture concept about the importance of sleep and breathing from womb to tomb. This is definitely not a book to refer to relevant chapters, but a must read from cover to cover so as to connect the dots in the big picture. She has hammered home the facts based on currently available research, some of it challenging traditional approaches which are still the accepted norm today. This book is not just for parents, but a must read for medical, dental and allied health practitioners especially those dealing with infants and children. It’s a paradigm shift moving from traditional ethos to site specific, tailored and an integrated approach in dealing with this condition which is truly a global evolutionary pandemic.”
