If you have been reading around your child's struggles at school or at home, you may have come across the term "primitive reflexes" and wondered what it actually means, and whether it has anything to do with what you are seeing in your own child. It is a term that sounds clinical, but the idea behind it is simple. This guide is here to explain what primitive reflexes are, why some children hold onto them for longer than expected, and what a sensible next step looks like if you think your child might be one of them.
What are primitive reflexes?
Every baby is born with a set of automatic movement responses called primitive reflexes. They are sometimes described as survival reflexes, because that is exactly what they are for. In the first weeks and months of life, before a baby has any voluntary control over their body, these reflexes help them feed, respond to sudden changes in position, and begin to make sense of the world through movement.
You may already be familiar with some of them without knowing their names. The reflex that makes a newborn's hand close tightly around a finger, the startle response to a loud noise or a feeling of falling, the way a baby's head turning to one side causes that arm to straighten. These are all primitive reflexes, and every baby needs them.
What is supposed to happen next
As a baby's brain and nervous system mature, these early reflexes are gradually inhibited. This usually happens through the natural movement of infancy: tummy time, rolling, crawling, pulling up to stand. Each of these ordinary baby movements plays a part in helping the nervous system move on from the automatic reflex response and replace it with controlled, voluntary movement instead. By around the first birthday, most of the primitive reflexes should have done their job and stepped back, making way for the coordination, balance, and postural control a growing child needs for sitting still, writing, reading, and managing their emotions.
For most children, this process happens quietly in the background and nobody ever needs to think about it. For some children, for reasons that are not always clear, one or more reflexes do not fully integrate. They remain active longer than they should, and the nervous system carries on responding to the world in that earlier, more instinctive way.
It is worth saying too that reflex integration is not limited to childhood. Although this guide is written with children in mind, primitive reflexes can be assessed and supported at any age, and it is never too late to look at whether they might be playing a part in how someone moves, learns, or manages their emotions.
A retained reflex rarely announces itself. It shows up quietly, in the ordinary details of a child's day.
What this can look like in everyday life
Retained reflexes do not tend to look like an obvious physical problem. Instead, they can show up as things that are often put down to character or effort: a tight, uncomfortable pencil grip, big emotional reactions that seem out of proportion to what triggered them, poor balance or frequent bumping into things, difficulty sitting still at a desk, losing their place while reading, or feeling sick on car journeys. None of these things are a child's fault, and none of them mean a child is not trying hard enough. They are often signs that part of the body's early developmental groundwork has not quite finished.
Any one of these signs on its own does not necessarily mean much. It is when a cluster of primitive reflexes have not integrated, rather than just one, that life tends to become noticeably more challenging for a child, and this is exactly the picture where reflex integration work tends to make the most difference.
What to do if you think your child has retained reflexes
If some of this sounds familiar, the most useful next step is a proper assessment rather than guesswork from a checklist. A standardised INPP assessment looks at a child's developmental history alongside a set of neuromotor tests, including balance, coordination, and specific reflex responses. This gives a clear, evidence-based picture of which reflexes, if any, are still present, and how they may be affecting your child day to day.
You do not need a diagnosis, a referral, or years of trying other things first. Many parents come to an assessment simply because something has not quite added up, and they want to understand why. An assessment does not commit you to anything beyond finding out what is going on, and it is often the point at which a lot of pieces start to make sense.
Why every child needs their own programme
One of the most important things to understand about this work is that no two nervous systems are the same. Two children can show very similar struggles at school and have entirely different patterns of retained reflexes underneath, or the same reflex affecting each of them in a different way. This is why a generic exercise sheet or an off-the-shelf programme rarely gets the best results. A programme designed around your child's own assessment findings, and reviewed as they progress, gives the nervous system exactly what it needs rather than a general approximation of it. This is the difference a personalised approach makes, and it is worth looking for when you are choosing support for your child.
Why progress takes time, and what contact looks like along the way
It is worth being honest about pace, because this is not a quick fix. The nervous system needs time to integrate new movement patterns, and that happens gradually, through consistent daily practice at home rather than through frequent clinic visits. For this reason, full review appointments are usually spaced every few months, giving the nervous system real time to respond to the current stage of the programme before it is reviewed and adjusted.
That does not mean you are left to get on with it alone in between. Regular contact between appointments, whether that is a quick check-in on how the daily movements are going, a question about something you have noticed, or simply reassurance that you are on the right track, is part of how the programme is supported. You are never waiting months in the dark for the next formal appointment.

If you recognise your child in any of this, you do not need to have all the answers before getting in touch. A short conversation is often enough to work out whether an assessment is the right next step, and there is no pressure to go further than that.
