Summary

 Today we’re diving into the nuanced world of circadian rhythm sleep syndromes, and how biological and environmental factors intersect in shaping our children’s sleep. My guest is Alex Mortlock, a registered clinical psychologist who has been in practice since 2010, with training rooted in evidence-based approaches to mental health. Alex will help us unpack what’s actually happening when a child’s sleep rhythm is out of sync, and why this is so often misunderstood. We talk about practical strategies, the role of light exposure and light therapy, and how melatonin can be used thoughtfully to support regulation. About Dr. Devon Price Alex Mortlock has been a registered clinical psychologist since 2010, trained at the University of Canterbury with a focus on evidence-based approaches to mental health assessment and treatment. His work is grounded in psychological science, with an emphasis on the interplay of emotion, cognition, and motivation. He uses evidence-based methods to help people make positive changes in their behaviour, fostering an environment of authenticity, acceptance, and understanding.

He lives in Christchurch, New Zealand with his wife, who is also a clinical psychologist, and their two over-analysed children. Curiosity, compassion, courage, and flexibility are the values that guide him through the professional and personal challenges that human life presents.
