Auditory processing

In this episode, Greg Dickens and I discuss recent news on how childhood vitamin D levels correlate with heart health, on the effects of sun exposure on multiple sclerosis, and how the month of a child’s conception affects their later metabolic health. We then talk about auditory processing - what it is, how it develops, and what children need in order to develop good auditory processing skills. Finally, we discuss whether we should be concerned about the long-term effects of microplastics in children.
