The Nervous System Piece Most Pediatricians Skip

Why polyvagal theory and yoga therapy belong in pediatric care — and what changes when a child's nervous system finally has a seat at the table.

When you bring your child to a pediatrician for anxiety, behavioral challenges, sleep struggles, or recurring stomachaches, the conversation usually moves in a familiar direction.

There's a screening tool. A referral, maybe. A discussion about medication, or a recommendation to try behavioral therapy. Sometimes a prescription, sometimes a wait-and-see. The visit is short. The lens is narrow.

And almost never — in our experience — does anyone ask the question that might matter most:

What is your child's nervous system doing right now?

Not their behavior. Not their symptoms. Their nervous system.

At Orzu Kids, this question sits at the center of how we work — because for many of the children we see, the answer changes everything that comes next.

Why the nervous system is the missing piece

Conventional pediatrics is built around the medical model: identify the symptom, name the diagnosis, treat the condition. It's a model that works beautifully for acute illness, broken bones, and infections. It works less well for the chronic, recurring, mysterious patterns that bring so many families to integrative pediatric care — the anxiety that won't respond to therapy, the stomachaches without a cause, the ADHD diagnosis that doesn't fully explain what's happening at home.

What these patterns often have in common is a nervous system that has been operating in a low-grade stress response for so long it has lost the ability to fully return to baseline. The body is doing exactly what it was designed to do — protect, alert, mobilize — but it doesn't know how to stop.

Most pediatric visits don't address this. There's no diagnostic code for it. There's no medication that targets it directly. And there's rarely time, in a fifteen-minute appointment, to even ask the question.

So the nervous system goes unaddressed. The symptoms persist. And families are left wondering why the standard interventions aren't working.

What polyvagal theory actually means for kids

Polyvagal theory, developed by Dr. Stephen Porges, offers a different way of understanding what's happening inside a dysregulated child.

In simple terms: the vagus nerve — the longest cranial nerve in the body — carries signals between the brain, the heart, the gut, and most of the major organs. It's the physiological backbone of how we sense safety, connection, and threat. When the vagus nerve is functioning well, a child can move fluidly between states: engaged at school, calm at bedtime, present at the dinner table, able to recover after something hard.

When the vagus nerve is under-toned or stuck in a defensive pattern, a child can't access those shifts as easily. They get stuck in mobilization (anxiety, hypervigilance, big behaviors) or in shutdown (withdrawal, fatigue, flatness). Their body reads ordinary moments as threatening and ordinary transitions as overwhelming.

Polyvagal-informed care isn't about teaching a child to "calm down." It's about helping the nervous system itself learn that it's safe enough to rest — through specific, evidence-based practices that work with the body rather than against it.

This is the lane Kimberly Castello holds at Orzu Kids.

Meet Kimberly: yoga therapy as nervous system care

Kimberly M. Castello is an IAYT-certified Yoga Therapist — a credential that takes years of clinical training beyond standard yoga teaching certification. Her work focuses on polyvagal theory, nervous system regulation, breathwork, mindfulness, and yoga therapy as applied to children and families.

What this looks like in practice isn't a kids' yoga class. It's a clinical session where Kimberly works with a child — and often with their parent — to teach the nervous system new patterns. Sometimes that means specific breath practices that activate the vagal "brake" the body uses to calm itself. Sometimes it's gentle movement that helps a child reconnect with internal cues they've learned to override. Sometimes it's simply teaching a kid what their body is doing and why, in language they can actually understand.

The work is unhurried. It's adapted to where each child is. And it's grounded in the same scientific frame that guides the rest of our practice: the body has wisdom, the nervous system can change, and the goal is regulation — not compliance.

How this fits into integrative pediatric care

Kimberly's work doesn't happen in isolation. It sits inside a larger framework where Dr. Arthi Khazanchi — a Board-certified Integrative Medicine Pediatrician — is looking at the same child through a different lens: functional medicine, homeopathy, Ayurvedic principles, genomic testing, nutritional counseling, mind-body medicine.

Together, this is what integrative pediatric care actually means at Orzu Kids:

• A child with anxiety isn't just given a referral. Arthi is looking at gut health, nutrient status, family history, and whole-system factors. Kimberly is working with the nervous system pattern directly.

• A child with ADHD isn't just labeled. The integrative approach considers nutritional contributors, sensory load, sleep, polyvagal patterns, and whole-child support — alongside any conventional care the family is also receiving.

• A child with chronic stomachaches isn't just told to wait and see. The gut-mind connection is real, measurable, and central to how we look at these patterns.

It's not that conventional pediatrics is wrong. It's that it isn't the whole picture. And for the kids who fall through the cracks of the medical model, the nervous system piece is often what's missing.

What changes when the nervous system gets a seat at the table

Parents who bring their children to Kimberly often describe what they notice in the language of small, real moments. A child who can sit through a haircut. A bedtime that isn't a battle. A morning where a sibling spat doesn't spiral into the whole day. The arrival of a child's actual personality — curiosity, humor, presence — in places where survival mode used to be.

These changes don't come from a chart or a consequence. They come from a nervous system that has, slowly, learned a new pattern.

And those changes don't require pulling your child out of any other care they're receiving. Polyvagal-informed work at Orzu Kids is designed to complement — not replace — conventional medical care, therapy, or anything else your family is already doing. It's adding the piece most pediatricians don't have time to address.

Where to start

If you've been working through the standard pediatric checklist for your child and something still feels unaddressed — if the anxiety isn't budging, if the behaviors don't respond to the usual interventions, if your gut keeps telling you there's a piece missing — you may be right.

A Complimentary Initial Case Review is the place to start. We'll listen to what you're seeing, look at the whole picture, and tell you whether our integrative approach — including Kimberly's nervous system work — is likely to be a fit for your child. No commitment. No pressure. Just an honest conversation.

Orzu means "may you be well in all aspects of your being." For us, that includes the part of your child's body that the standard appointment doesn't make time for.
