Why Your Child’s Nervous System May Be the Missing Piece in Their Health

Dr. Jenny McMullen

If you’re reading this, you likely care deeply about your child’s long-term health. You want more than temporary fixes. You want resilience. Regulation. Real answers.

What many parents don’t realize is that nearly every challenge a child experiences — from sleep struggles and colic to focus issues and immune stress — has one system in common:

The nervous system.

When the nervous system functions well, the body functions well. When it is overwhelmed, stressed, or dysregulated, symptoms begin to surface.

The Nervous System: Your Child’s Master Control System

The nervous system coordinates every major function in your child’s body. It controls digestion, immune response, sleep cycles, emotional regulation, coordination, growth, and cognitive development.

In children, this system is still developing. From birth through adolescence, the brain and spinal cord are constantly forming new neural pathways. This makes early life a powerful window for development — but also a vulnerable one.

When communication between the brain and body is clear and balanced, children adapt to stress more efficiently. They sleep better. They digest better. They regulate emotions better. They recover from illness more smoothly.

When that communication becomes disrupted, even subtly, the body begins to compensate.

Sometimes that compensation looks like:

  • Colic or reflux
  • Frequent ear infections
  • Difficulty sleeping
  • Sensory sensitivities
  • Behavioral challenges
  • Delayed or altered developmental milestones
  • Chronic congestion or immune struggles
  • Trouble focusing

These are not random issues. They are often signs that a child’s nervous system is working harder than it should to adapt.

Common Stressors That Affect Kids

One of the biggest misconceptions I see is the belief that stress must be dramatic to impact a child’s health. In reality, many nervous system stressors are part of everyday life.

Some examples include:

  • Birth interventions or prolonged labor
  • Cesarean deliveries
  • Early feeding difficulties
  • Frequent falls while learning to crawl or walk
  • Poor posture or prolonged device use
  • Busy schedules and overstimulation
  • Emotional stress within the family

None of these automatically cause problems. The key factor is adaptability. How well can your child’s nervous system process and respond to these inputs?

When adaptability becomes overwhelmed, regulation declines.

This is where chiropractic care, viewed through a neurological lens, becomes powerful.

What Pediatric Chiropractic Actually Does

There is often misunderstanding about pediatric chiropractic care. For children — especially infants — adjustments are gentle, specific, and neurologically focused. The goal is not force. It is precision.

By addressing areas of spinal tension or misalignment that may be interfering with neural communication, we help reduce stress on the nervous system. When interference decreases, the brain and body communicate more efficiently.

And when communication improves, regulation improves.

Families frequently report:

  • Longer, more restful sleep
  • Calmer behavior
  • Improved digestion
  • Fewer immune flare-ups
  • Better focus and coordination
  • Easier transitions and emotional regulation

These improvements are not because we are “treating” sleep, digestion, or behavior. They occur because we are supporting the system that controls all of those functions.

A Colic Story That Changed Everything for One Family

A young couple brought in their six-week-old baby who had been diagnosed with colic. She cried for hours each evening. She arched her back during feeds. She slept in short, restless bursts. Her parents were exhausted and feeling helpless.

Colic is often described as something babies simply “grow out of.” But when I evaluated her, I saw signs of nervous system stress — likely connected to birth strain and early tension patterns.

Her adjustments were extremely gentle. No cracking. No force.

Within the first few visits, her parents noticed shorter crying episodes and more relaxed feeding sessions. Over the next several weeks, her sleep began to lengthen. The evening crying spells decreased significantly. Her body appeared more settled.

Nothing about her changed overnight. But her nervous system began regulating more efficiently once interference was reduced.

Instead of asking, “How do we suppress the crying?” we asked, “Why is her nervous system struggling to adapt?”

That shift in perspective changes everything.

My Personal Journey with Nervous System Healing

My professional passion for nervous system care is deeply personal.

After my son experienced a hypoxic brain injury, our family entered a world of uncertainty. In the beginning, the focus was on managing symptoms and addressing immediate medical needs to save his life. But we always had a different question in mind:

How can we support his nervous system so his body can heal and develop as fully as possible?

That shift toward nervous system regulation became foundational in his progress and in how I now approach pediatric care. It reinforced what I had already seen clinically — that the nervous system is not just another system. It is the system that influences every other system.

When we support it intentionally, the body’s capacity to adapt increases.

Is Your Child’s Body Struggling to Adapt?

You know your child better than anyone. If you’ve felt that something is “off,” even if you’ve been told everything is normal, trust that instinct.

You do not have to wait for a diagnosis to support your child’s nervous system.

You do not have to accept chronic stress patterns as “just how they are.”

And you do not have to navigate it alone.

If you are curious whether nervous system support could help your child — whether they are dealing with colic, sleep issues, immune stress, focus challenges, or you simply want to be proactive — I invite you to schedule a complimentary phone call.

During that call, we’ll discuss your child’s specific concerns, review what you’re noticing at home, and determine whether our approach is a good fit for your family.
