In this episode, Greg Dickens and I discuss recent news on how breast milk varies during the day, how breastfeeding affects the milk microbiome, and how the age at which a child gets their first smartphone influences their later mental health. We then discuss disgust - what it is, why it’s good, and when it can be bad. We talk about how we can help children set up healthy levels of disgust. Finally, we talk about how the age at which a child walks affects their long-term hip health.
