Why We Need to Build the Brain Before We Fix the Gut, and Why We Can't Ignore the Gut Either

As parents, it's natural to want the quickest solution. 

If your child struggles with their speech or has sensory issues, often has meltdowns, can’t concentrate, suffers from anxiety or learning difficulties, it's easy to focus on the symptom that's causing the most difficulty today.

But after working with hundreds of families, I've learnt something that has fundamentally changed how I approach child development. Brain Development has worked with many children over the years and seen excellent results, with just one of parent saying:

"We've seen a remarkable change in one young boy, not because we chased behaviours, but because we built the neurological foundations first. Now we're supporting the biology that's allowing those new brain networks to thrive."

The brain develops from the bottom up.

The body either supports that development, or it holds it back. Recently I worked with a young boy whose journey beautifully illustrates why we need to look at the whole child, not just the diagnosis.

The Child Who Couldn't Access His Potential

When I first met him, he certainly wasn't lacking intelligence. However, he was trapped in a nervous system that was working incredibly hard just to stay organised. He had retained primitive reflexes throughout his body. His movements were immature, and his body awareness was poor. He struggled to regulate his emotions. Everyday tasks required enormous effort.

Although he wanted to engage with the world, his nervous system simply wasn't ready to support the higher skills we were asking of him.

Instead of immediately focusing on his learning process at school or behaviour, we started somewhere very different. We went back to the foundations.

The Brain Builds Like a House

When building a house, you don't start with the roof: you begin with the foundations. The brain develops in exactly the same way.

Before a child can consistently properly pay attention, develop language and social skills, emotionally regulate and executive function, their nervous system needs to feel a sense of safety. They also need to have developed:

• postural stability, 

• body awareness, 

• organised sensory processing, 

• efficient brainstem regulation. 

If these foundations remain immature, the higher parts of the brain have to work much harder just to complete everyday tasks.

We Focus on Movement Before Cognition

For the first stage of his programme, we didn't ask him to sit still and learn. Instead, we helped his nervous system organise itself through particular movements.

His programme focused on:

• primitive reflex integration

• vestibular development

• cerebellar activation

• brainstem regulation

• body awareness

• bilateral coordination 

• postural control

Alongside this, we supported key cranial nerve pathways, particularly the trigeminal nerve, vagus nerve and oral motor system using gentle sensory input, breathing, vibration and purposeful movement. 

These approaches aimed to improve the quality of sensory information reaching the brain while creating opportunities to practise more mature movement patterns.

The goal wasn't simply to teach exercises, but to give his brain the developmental experiences it may have missed during earlier stages of life.

Then Something Started to Change

Over the following months, something wonderful happened.

His balance and coordination improved.

He became calmer.

His emotional regulation improved and so did his confidence.

He had more control over his body.

Perhaps most importantly...

Movements no longer looked arduous. 

His brain was beginning to automate skills that previously required conscious effort.

This wasn't simply because he had practised.

It was because his nervous system had become more organised.

In our clinic, we often describe this as moving through the developmental hierarchy.As the lower brain becomes more efficient, the cortex no longer has to spend so much energy simply maintaining posture and regulation.

That energy becomes available for learning, creativity and relationships.

But We Didn't Stop There

This is where I think many practitioners make one of two mistakes. Some focus only on movement, others focus only on nutrition. In reality...

The brain and the body are constantly talking to each other.

Once this child's nervous system became more organised, we wanted to understand whether anything inside his body was making it harder for that progress to continue.

So we investigated further.

Looking Beneath the Surface

His functional laboratory testing didn't reveal one dramatic problem. Instead, it revealed several smaller systems that all needed support.

We found evidence suggesting:

• ongoing neuroinflammatory load 

• immune activation 

• elevated oxalates

• increased demand for several B vitamins

• mineral insufficiencies

• subtle digestive dysfunction

• increased detoxification demands

• mild microbial imbalance

Importantly, the overall picture was not one of severe disease or a body that was "broken." Rather, it suggested several interconnected systems that could be working more efficiently and that may be increasing the demands on his nervous system. 

Think about it like driving a car. Movement work taught him how to drive. Now we're making sure there's enough fuel in the engine.

Why Nutrition Matters for Brain Development

Every thought...

Every movement...

Every new neural connection...

Requires energy.

The brain depends on a continuous supply of nutrients to build and maintain these connections.

If digestion is inefficient...

If important minerals are depleted...

If inflammation is elevated...

If the immune system is working overtime...

The brain has fewer resources available for development.

That doesn't mean nutrition alone will solve developmental challenges.

But it does mean the brain works best when its biological environment supports growth.

We Build From the Bottom Up

One thing I explain to parents is that we never want to rush into aggressive interventions.

Instead, we build in layers.

First:

✔ Organise the nervous system.

Then:

✔ Improve movement.

Then:

✔ Support digestion.

✔ Replenish nutrients.

✔ Reduce inflammation.

✔ Strengthen the microbiome.

✔ Optimise detoxification pathways.

Each layer creates a better environment for the next.

That staged approach mirrors the recommendations from his functional testing, which prioritised rebuilding digestion, nutrient status and resilience before progressing to more targeted microbial support. 

Progress Doesn't Always Look Like You Expect

Parents often ask me:

"When will my child’s speech improve?"

"When will their concentration improve?"

"When will school get easier for them?"

Sometimes the biggest neurological changes happen long before those skills become obvious.

A child who:

• recovers from frustration more quickly, 

• tolerates movement that previously caused distress, 

• develops better balance, 

• becomes more emotionally flexible, 

• enjoys social interaction more, 

  
  

is showing us that the brain is reorganising itself.

Those changes create the conditions for future learning. They are not small victories: they are the foundations of everything that comes next.

The Future Is Built on Foundations

This young boy's journey is still continuing. We're still supporting his nervous system. We're still helping his brain mature through movement. We're now also optimising the environment in which that brain is developing through nutrition, gut health and targeted nutritional support.

The exciting part is that we are no longer simply managing symptoms; we are helping his body create the conditions for development.

Because when the nervous system feels safe...

When the body has the nutrients it needs...

When movement becomes organised...

The brain is finally free to do what it was designed to do.

Develop.

Support Your Child’s Development

At Brain Development UK, we don't believe children are defined by a diagnosis. We believe every child has a developmental story.

Our job is to identify which foundations are still developing, support the systems that need to mature next, and create the conditions in which the brain can continue to grow.

Sometimes that starts with movement.

Sometimes it starts with nutrition.

Most often, it requires both.

Because lasting change happens when we support the brain and the body together.
