The Biology of Trauma® With Dr. Aimie Do Babies Who Cry It Out Get Anxiety and Addiction Later in Life?
The truth is, early parenting choices, like sleep training and letting babies cry it out, can affect how their brain and body develop for years to come. Many well-meaning parents follow these popular methods, only to see their kids later struggle with anxiety, depression, or behavioral issues that seem to come out of nowhere. That’s because early attachment and nervous system development shape a child’s mental health in ways we don’t always see.
Everything that happens in the first years of life, from how you respond to your baby’s cries to how connected they feel, helps build their brain, nervous system, and their ability to feel safe and calm. Even common parenting habits can create hidden stress, making it harder for children to grow into resilient, emotionally healthy adults.
In this episode, Dr. Darcia Narvaez joins Dr. Aimie to talk about what babies really need for healthy brain development, emotional safety, and attachment. You’ll also learn how parents and practitioners can begin to repair early childhood trauma and help heal the nervous system, no matter the age.
You’ll hear about:
- How sleep training and crying it out disrupt a baby’s developing nervous system
- The link between early separations and anxiety, depression, and attachment issues later in life
- How your own childhood experiences influence your health, relationships, and parenting style
- Practical ways to rebuild connection and help your child’s nervous system heal
- Why the vagus nerve is essential for emotional regulation in children
- How common newborn medical procedures can cause lasting trauma
- Why children need love and connection, not constant performance for approval
Whether you’re a practitioner wanting to understand how early attachment trauma affects adult clients, or a parent looking for nervous system regulation techniques and coregulation strategies to support your child, this episode offers science-backed insights and practical tools you can use right away.
