# Why Isn't My Child Talking? by Rebecca Erickson

> A mother's guide to what biology can tell us about speech delay, behavior, regression, and the nervous system, with a foreword by pediatric neurologist Richard E. Frye, MD, PhD.

Why Isn't My Child Talking?: What Biology Can Tell Us About Speech Delay, Behavior, Regression, and the Nervous System. Written by Rebecca Erickson, with a foreword by Richard E. Frye, MD, PhD (pediatric neurologist and autism researcher). Coming soon in paperback and Kindle.

When a child struggles with speech, behavior, sleep, attention, or regulation, parents are often told to wait, manage symptoms, or focus only on therapy. But what if biology is part of the story? In this book, Rebecca Erickson explores how oxidative stress, energy production, methylation, cell signaling, gut health, and nervous system support may influence a child's ability to communicate, connect, and thrive.
Written for parents in clear, compassionate language, this book offers a framework for understanding why some children are overwhelmed and what supportive steps may help.

Parents often find the book after searching for: speech delay; a child who stopped talking or lost words; developmental regression; adhd; pans/pandas; autoimmune encephalitis; immune activation; neuroinflammation; sensory processing issues and sensory overload; emotional regulation difficulties; meltdowns, aggression, or other behavior problems.
The book is educational and is not medical advice; it does not diagnose or treat any condition.

## Questions and answers

### Who is this book for?

Parents and caregivers of a child who is not talking yet, has lost words, or is struggling with sleep, eating, behavior, sensory overload, or regulation. Rebecca's family story includes autism and speech delay, but the patterns she describes are not limited to autism.
Therapists, teachers, and clinicians who work with these families may find it a helpful window into what parents see at home.

### Do I need a science background to understand it?

No. The book is written for parents in plain language, with stories from daily family life and illustrations that explain the key ideas. A Parent's Guide to Key Terms at the back explains the scientific words in everyday language.

### Is this book medical advice?

No. It is an educational book that shares one family's experience and the framework that helped them understand what they were seeing. It does not diagnose or treat any condition. Please talk with a qualified healthcare professional before starting, stopping, or changing any medication, supplement, therapy, or diet.

### What is the Core Support Plan?

It is the ordered framework Rebecca describes in Part III. It grew out of the Biological Order of Repair: the idea that the body responds differently depending on what has already been stabilized underneath it, so the order of support matters. The book ends with the Core Support Plan at a Glance.
You can also explore the plan and its tools at [AutismNutrients.com](https://autismnutrients.com/).

### Who wrote the foreword?

Richard E. Frye, MD, PhD, a pediatric neurologist and autism researcher. He earned his MD and PhD at Georgetown University and trained in child neurology and behavioral neurology at Boston Children's Hospital. His research looks for medical and biological problems that can make speech and development harder for a child, including differences in folate metabolism, cellular energy, and immune function.
In the foreword, he describes how families' questions shaped his career. What parents noticed at home, especially changes in language, helped guide his research from the clinic to a placebo-controlled clinical trial. He explains why Rebecca's story resonates with him: her attention to the details of daily family life, her plain-language look at the biology behind them, and her view of progress beyond spoken words.
He also notes that her framework should be considered alongside each child's own medical history and care. He closes with encouragement for parents to share what they observe, and a reminder to his fellow physicians of how much families can teach them.

### Is there a companion workbook?

Yes. The Parent Study Guide & Reflection Workbook follows all 26 chapters in order, with guided questions that help you connect the book to your own child's story. It is meant to be read beside the book, not instead of it.

### When is the book coming out?

Coming soon in paperback and Kindle. Sign up for the free sample and you will get an email when the release date is announced, and another when the book is available to order.

### What is in the free sample?

A 21-page PDF with a short letter from Rebecca, the full table of contents, Chapter 1, and an excerpt from Chapter 21, "The Test We Didn't Understand." It arrives by email a minute or two after you sign up.
