Otoacoustic emissions are clinically important because they are the basis of a simple, non-invasive test for hearing defects in newborn babies and in children who are too young to cooperate in conventional hearing tests. Many western countries now have national programmes for the universal hearing screening of newborn babies. Periodic early childhood hearing screenings program are also utilizing OAE technology. One excellent example has been demonstrated by the Early Childhood Hearing Outreach Initiative at the National Center for Hearing Assessment and Management (NCHAM) at Utah State University, which has helped hundreds of Early Head Start programs across the United States implement OAE screening and follow-up practices in those early childhood educational settings. The primary screening tool is a test for the presence of a click-evoked OAE. Otoacoustic emissions also assist in differential diagnosis of cochlear and higher level hearing losses (e.g., auditory neuropathy).
I enjoyed reading Nourishing Traditions (NT) and have incorporated some of the information from that book into my family's diet. It also prompted me to delve into some areas of nutrition research that I hadn't read before NT. I expected this book to take a similar approach to child care (i.e. present qualitative and quantitative research, give an overview of historical trends, and present ideas from various cultures). I had high hopes for this book, since Sally Fallon was once again listed as an author, but after reading this book perhaps I should search for more from Mary Enig (the co-author of NT, but not on this book).
OAEs are considered to be related to the amplification function of the cochlea. In the absence of external stimulation, the activity of the cochlear amplifier increases, leading to the production of sound. Several lines of evidence suggest that, in mammals, outer hair cells are the elements that enhance cochlear sensitivity and frequency selectivity and hence act as the energy sources for amplification. One theory is that they act to increase the discriminability of signal variations in continuous noise by lowering the masking effect of its cochlear amplification.
I must admit I am surprised that with the concept of Nourishing Traditions being about adopting traditional methods of preparing foods as observed in ultra-healthy non-western people groups, I expected the book on baby and child care to promote more traditional and indigenous ways of nurturing (not just nourishing) little ones, such as babywearing and co-sleeping. I guess we always have The Continuum Concept by Jean Liedloff for that!

My name is Kara Downing but now days I go by Miss Kara. I grew up in south eastern Colorado on a 2500 acre farm with my brother and sister. I was the youngest sibling and always wanted a younger brother or sister. As a young child I was always helping take care of my younger cousins and I loved babysitting. My grandma was an elementary teacher and I remember going to help in her classroom and the idea of teaching seemed like so much fun. I believe all of these factors helped my find my passion with working with children.
