Serve and Return: Building healthy relationships for young children and their caregivers

Co-Executive Director of the Center on the Developing Child and podcast host Tassy Warren is joined by the Center’s Faculty Director, Dr. Stephanie Jones, and Dr. Junlei Li, Saul Zaentz Senior Lecturer in Early Childhood Education at the Harvard Graduate School of Education, to explore the evolution of serve and return and what we’ve learned about the influence of relationships on early childhood development over the past 20 years. Drs. Jones and Li will share how the concept has helped shift our understanding of the importance of early relationships and how that thinking has evolved into more recent concepts such as “early relational health.” The conversation also looks beyond individual relationships to consider the broader ecosystem in which relationships develop—including the environments that shape caregivers’ ability to build strong, responsive relationships with young children—and how we can better support healthy relationships in policy and practice.

Toxic Stress: Protecting the Foundation

What is toxic stress? What effects can it have on a child’s body and development, and how can those effects be prevented? What does it mean to build resilience? This episode of The Brain Architects explores what “toxic stress” means, and what we can do about it. Host Sally Pfitzer is once again joined by Center Director Dr. Jack Shonkoff as they dive into the different types of stress, including what makes certain stress “toxic,” while other stress can be tolerable or even positive for children. They discuss the effects that toxic stress can have on developing brains, as well as what it means to be resilient to sources of stress, and how parents and caregivers can help encourage that resilience in children. Dr. Shonkoff also emphasizes the point that, even for those who may have experienced toxic stress, “it’s never too late to make things better.” Then, listen to a panel discussion featuring Pediatrician Dr. Kathleen Conroy, Community Mental Health Worker Cerella Craig, Professor and Researcher Dr. Megan Gunnar, and Training Director for Rise Magazine Jeanette Vega, as they discuss the various ways in which they encounter toxic stress and its effects in their work. The panelists speak openly about how toxic stress can affect families and children—including ways in which the systems set up to help can be the cause of further stress—and how to talk about toxic stress in a way that doesn’t make things feel hopeless to those who have experienced it. They also dig into strategies they employ in their various fields to help children and families deal with stress, and move what might be toxic stress back to tolerable levels.
