Why You Need an Expert in Primitive Reflex Integration (and Why Order Matters)

Have you ever noticed that some children can read the words on a page but struggle to understand what they have read? Or that a child may be bright and curious, yet their body or emotions seem to be working against them? This is often because the brain develops in a very specific order, and when some early developmental stages are skipped or incomplete, it can make higher-level skills harder to master.

The Brain Builds from the Bottom Up

Think of the brain as a house. The foundation is the lower brain, which develops first. Each level above depends on the stability of the one below. The last parts to mature are the fine control systems, such as the eye muscles that allow us to track, focus, and read for understanding. If the lower levels of the brain are not well organised, those higher skills can be shaky.

The vestibular system sits right at the base of this foundation. It is the part of the brain that controls balance and movement. When it is strong, we can hold our body still when we need to (static balance) and move smoothly when we are active (dynamic balance). The vestibular system gives the brain a sense of where the body is in space, helping every other part of the brain know what to do next.

The Role of the Moro Reflex and Emotional Regulation

Sitting just above the vestibular system is the Moro reflex, also known as the startle reflex. This reflex is part of the baby’s built-in safety system. It activates whenever a sudden movement, sound, or change in light occurs. When the Moro reflex integrates properly, it helps the child develop emotional regulation, body control, and a sense of safety in the world.

If the Moro reflex remains active beyond infancy, the nervous system stays on alert. The child may feel easily overwhelmed, anxious, or reactive. When this happens, the brain is using energy to stay in survival mode rather than learning mode. Emotional regulation has several layers that build one upon another: feeling safe, identifying emotions, calming the body, and choosing a response. A stable Moro reflex allows these stages to grow naturally.

The Chain of Reflexes: How Each One Depends on the Other

Primitive reflexes work together like a domino chain. Each reflex is designed to prepare the brain and body for the next developmental step. When one reflex fully integrates, it “knocks over” the next domino, allowing smooth progression.

The key reflexes in this chain include:

• Moro Reflex – the startle reflex that activates our survival response.

• Tonic Labyrinthine Reflex (TLR) – helps with head and body alignment, balance, and coordination.

• Landau Reflex – develops postural control, spinal strength, and the ability to lift the head against gravity.

• Symmetrical Tonic Neck Reflex (STNR) – supports the transition from crawling to upright posture and later helps with the ability to sit and be still and focusing at a desk and general concentration.
  

Each of these reflexes needs the others to be stable. If one domino remains standing, it can interrupt the chain and cause challenges in movement, learning, or emotional control. For example, a retained TLR can cause poor posture and fatigue, which can make focusing in class difficult. A retained STNR can lead to fidgeting, slouching, or trouble sitting still to read or write.

The Domino Analogy

When I explain this to parents, I describe it like a domino game. Each milestone a baby achieves, rolling, crawling, sitting, walking, knocks down one of these primitive reflex dominoes. As the dominos fall, the brain is wiring stronger connections, preparing for more advanced skills such as reading comprehension, handwriting, and emotional maturity.

My role as a neurodevelopmental therapist is to look at which dominos are still standing and what challenges they are creating. Sometimes a child has learned to compensate, but the original reflex is still active in the background, quietly affecting balance, focus, or confidence. In these cases they seem really capable some of the time but other days things fall apart and they seem vastly different with their capabilities, more than just being tired.

Why Order Matters

You cannot build the upstairs of the house if the foundation is uneven. Similarly, you cannot integrate higher-level skills until the lower-level reflexes are stable. Working on reflexes out of order can confuse the nervous system, much like trying to knock over dominos starting in the middle of the line.

An expert in primitive reflex integration understands how these reflexes interact and how to strengthen them in the correct sequence. By identifying which reflexes are active, and addressing them in order, we can help the brain find stability again or for the first time.

When the base systems like balance and emotional safety are secure, the child can finally use their full potential. Reading comprehension, emotional control, and coordination all become easier because the brain and body are working together, not against each other.

The Next Step

At Move Learn Connect, we specialise in exercise-based programs that integrate primitive reflexes in the correct developmental order. This process builds the strong foundation every child needs for learning, confidence, and calm.

If you’ve noticed that your child can read but struggles to understand, or that they are constantly moving, anxious, or easily frustrated, it may be time to look at which reflex dominoes are still standing. Together, we can help them find balance, inside and out.
