Why Is My Child So Anxious? The Answer Might Be in Their Nervous System

Think Thrive | Rebecca Gough, Licentiate of INPP and Tomatis® Level 2 Practitioner

You know that feeling when you are sitting quietly and someone makes you jump? Your heart races, your arms fly out, your whole body floods with adrenaline. For most of us, it passes in seconds. We laugh it off and carry on.

For some children, that feeling never really passes. Their nervous system is on high alert, almost all of the time.

If your child startles easily, struggles to settle, worries more than other children their age, or seems to go from calm to overwhelmed very quickly, you may have been told it is just their personality. Or anxiety. Or a sensory sensitivity. Those things may be true. But there is often something happening underneath all of that, something that does not get talked about nearly enough.

It is called the Moro reflex.

What Is the Moro Reflex?

The Moro reflex is one of the primitive reflexes: automatic, involuntary movements that are present from before birth and serve an important survival purpose in the early months of life. When a newborn baby feels a sudden movement or sound, the Moro reflex causes their arms to fling outward and then pull back in, often followed by crying. It is sometimes called the startle reflex, though technically the two are slightly different.

This reflex is completely normal and essential in a newborn. It helps stimulate breathing, alerts caregivers, and supports the development of early neurological pathways. The research is clear on this: primitive reflexes play a foundational role in healthy early development (Goddard Blythe, 2012; Gieysztor et al., 2018).

The critical thing is that the Moro reflex is designed to integrate, meaning it fades and is replaced by more mature, controlled responses, usually by around four months of age. When that integration happens on time, the child develops the ability to respond calmly to unexpected stimuli. Their nervous system learns to assess a situation before reacting.

But what happens when it does not integrate?

When the Moro Reflex Stays Active

A retained Moro reflex keeps the nervous system in a near-constant state of readiness. The child's brain is, in effect, scanning the environment for threats at all times. This is not a choice. It is not naughtiness or over-sensitivity. It is an automatic neurological response that the child has very little control over.

The signs can look very different from child to child. Some of the things parents and teachers commonly notice include:

Emotional regulation difficulties. The child becomes overwhelmed quickly, particularly in noisy or busy environments. Transitions are hard. They may cry, shut down, or lash out in situations that seem manageable to others around them.

Anxiety and worry. A hypervigilant nervous system tends to read situations as more threatening than they are. This can show up as separation anxiety, fear of new situations, difficulty sleeping, or a tendency to catastrophise.

Sensory sensitivities. Bright lights, loud sounds, certain textures, or unexpected touch can feel unbearable. This is because the same neurological state that keeps the Moro reflex active also affects how sensory information is processed.

Difficulty concentrating. It is very hard to focus on learning when part of your brain is busy watching the door.

Physical signs. Poor posture, shallow breathing, a tendency to hold tension in the shoulders and jaw, or difficulty with balance and coordination can all be connected.

Research published in peer-reviewed journals has consistently found associations between retained primitive reflexes and difficulties with emotional regulation, sensory processing, and learning (Pecuch et al., 2020; Kalemba et al., 2023). These are not fringe ideas. They are supported by decades of neurophysiological research, including the work of Sally Goddard Blythe and the Institute for Neuro-Physiological Psychology (INPP), on whose methods Think Thrive is built.

Why This Matters, and What Can Be Done

The important thing for parents to understand is that a retained Moro reflex is not a life sentence. The brain is remarkably adaptable, and with the right structured movement programme, integration can happen even in older children and adults.

At Think Thrive, every child begins with a thorough neurodevelopmental assessment. This includes looking at the full picture of primitive reflex retention, not just the Moro reflex, because reflexes do not work in isolation. They form a developmental sequence, and understanding where that sequence has become interrupted is the starting point for everything we do.

The programme that follows is built on the INPP method, developed over more than 50 years of clinical research and practice. It uses gentle, specific movement exercises, done daily at home, that support the nervous system to complete the developmental work it did not finish in infancy. This is not a quick fix. It is a gradual, evidence-informed process that works with the child's neurological development rather than trying to manage symptoms from the outside.

You Do Not Have to Keep Guessing

If you are reading this and recognising your child, the most useful thing you can do is find out what is actually going on in their nervous system. Not through a checklist from the internet, but through a proper assessment with someone who understands neurodevelopmental therapy.

Think Thrive is the only practice in West Yorkshire offering both INPP and Tomatis® therapy. Rebecca Gough holds the Licentiate qualification from INPP and is a Tomatis® Level 2 Practitioner, bringing together two of the most established and research-supported approaches to neurodevelopmental support available.

If your child is struggling, and if what you have read here sounds familiar, please get in touch. An initial conversation costs nothing, and it could change everything.
