In today's world, the mental health of infants and young children is more important than ever. As caregivers, educators, and health professionals, we play a vital role in supporting their emotional and psychological development. Our upcoming online class, launching in October 2025, is crafted to provide you with the foundational knowledge and practical skills needed to nurture these precious early years. Over four engaging weeks, we will uncover key concepts that are essential for fostering healthy emotional growth in our youngest children.
The significance of mental health during early childhood is backed by research. Studies show that 90% of a child's brain development occurs before the age of five. This means that early experiences shape not only their emotional responses but also their social interactions and cognitive abilities. By equipping ourselves with knowledge in infant and early childhood mental health, we can create nurturing environments that build resilience and secure attachments.
Week 1: Polyvagal Theory and "Felt Safety"
Our first week focuses on Polyvagal Theory, which explains how our nervous system affects our emotions and social behaviors. Understanding this theory is crucial for caregivers as it highlights the concept of "felt safety."
Felt safety is how a child perceives safety within their environment. For instance, studies have shown that when children feel safe, their cortisol levels drop, leading to better stress management and improved learning capabilities. Caregivers will learn practical strategies to enhance felt safety, such as maintaining a calm demeanor and establishing predictable routines, both of which promote exploration and learning.

Week 2: "Serve and Return" and Co-Regulation
In the second week, we explore the essential "serve and return" interactions that take place between caregivers and children. This concept is fundamental to healthy brain development and emotional well-being.
"Serve and return" involves responding to a child’s signals, whether they are smiles, cries, or gestures. For example, when a caregiver responds to a child's cooing with eye contact and a smile, it reinforces the bond and builds communication skills. Additionally, we will tackle co-regulation, which is crucial for helping children manage their emotions. Caregivers will gain insights into recognizing a child's emotional cues and providing the appropriate support, thus fostering emotional regulation and resilience.
Week 3: Responding to Big Feelings
The third week addresses the often daunting task of responding to children's big feelings. Young children can experience intense emotions, and understanding how to navigate these situations makes a big difference.
We will provide strategies for validating a child's emotions. Creating an emotionally safe space is crucial for fostering emotional intelligence. The goal is to empower caregivers to handle emotional challenges with confidence and compassion, ultimately helping children develop resilience.

Week 4: Building a Supportive "Village"
In our final week, we will emphasize the importance of creating a supportive "village" around children. This timeless concept highlights the collective effort required from caregivers, family, friends, and community members.
We will discuss how to establish a network that nurtures healthy relationships and emotional wellbeing. For example, joining local parenting groups or community organizations can connect you with other caregivers and provide additional resources. Sharing information and experiences can significantly enhance a child’s mental health. A strong support network ensures that children have access to various supportive relationships they need to thrive.
