CCC-SLP, owner of Innovative Therapy 4 Kids Inc. and Innovative Oral Solutions Inc. and the creator of the My Mouth Works Program and Healthcare Platform ""Dr. Karen Parker Davidson, RN is a true expert and has an amazing passion for training and education of professionals and parents/patients who have improper nasal function. It is so important for young children to quietly breathe through their nose both day and night and NOT SNORE. This book covers many facets and dives deep into subjects that usually are not discussed, especially in a book for the consumer. This book is not only for the consumer, but any professional interested in their patient's breathing, airway, and nasal function. ""The Nose Knows"" is an area that Karen is very passionate about. Objective testing of nasal function and nasal resistance is an important aspect of many specialties in medicine and dentistry. When Karen and I met, I was so impressed by her knowledge and scientific approach to the importance of objectively measuring nasal breathing and how it affects a child's total growth and development. I highly recommend that everyone read this book and then read it many more times as you will absorb much more information and become educated in the world of THE NOSE"" - WILLIAM E.
