Retained Primitive Reflexes
In the first year of life, babies are born with a set of automatic, instinctual movements called primitive reflexes. These reflexes help them survive, develop, and interact with their world — think of the rooting reflex for feeding or the grasp reflex when a baby wraps their fingers around yours. As the brain matures, these reflexes are usually inhibited to make way for more voluntary, refined movements. But sometimes, this natural process doesn’t happen as smoothly as we’d expect.
When primitive reflexes are retained beyond their typical timeframe, they can contribute to a range of challenges — some subtle, some more pronounced. From an osteopathic perspective, this is where things get particularly interesting.
What Causes Primitive Reflexes to Persist?
Several factors can disrupt the normal integration of reflexes, including:
· Difficult or traumatic births
· Prematurity
· Developmental delays
· Early illnesses or hospitalisation
· Limited tummy time or movement opportunities in early infancy
These reflexes don’t just disappear on their own; they are "integrated" through movement and neurological maturation. This is one of the reasons why crawling, rolling, and other transitional milestones are so important. For example, if a baby skips crawling, it might indicate — or contribute to — retained reflexes and influence future coordination or learning.
What Retained Reflexes Might Look Like?
In older children, retained reflexes may show up as:
· Poor balance or coordination
· Difficulty sitting still or concentrating
· Sensory sensitivities
· Delayed fine motor skills or handwriting issues
· Difficulties learning to read or ride a bike
· Poor posture or clumsiness
· Continued bed wetting
· Motion sickness
How Can Osteopathy Help?
Osteopaths take a whole-body approach to assess and support babies and children. When we suspect retained reflexes, we don’t just look at movement — we look at the entire system:
· Is there tension in the neck or base of the skull that could be impacting nervous system regulation?
· Is there fascial restriction limiting movement?
· Is the child avoiding certain positions that are key for reflex integration?
Through gentle hands-on treatment, we support nervous system regulation and development, reduce tension, and promote the kind of movement that helps integrate these reflexes. This is often paired with simple home-based movement therapy to support integration between treatments.
Osteopathic treatment can be a valuable part of a broader team approach, working alongside occupational therapists, speech pathologists and other allied health professionals to support each child's unique needs.
Retained primitive reflexes may sound subtle, but they can have a significant impact on a child’s function, learning, and wellbeing. If you're noticing signs that your child may be struggling with coordination, posture, or sensory processing, it may be worth exploring whether retained reflexes are part of the picture.
