Understanding Primitive Reflex Integration
Shauni Snow, COTA-L
Where Primitive Reflexes Come From
Primitive reflexes originate in the brainstem and are present before birth. They help newborns adjust to life outside the womb by supporting early movement, sensory development, and neural growth.
Why Primitive Reflexes Are Important For Developmental Growth
These reflexes support:
Rolling
Crawling
Sitting
Walking
Hand-eye coordination
Visual tracking
Balance
Emotional regulation
Why Reflex Integration Matters As A Child Grows
If reflexes remain active beyond infancy, they can interfere with developmental milestones, coordination, attention, emotional regulation, and fine motor skills.
We All Revert to Primitive Reflexes Under Stress
Primitive reflexes remain in the brainstem throughout life. During moments of stress or fight-or-flight responses, our nervous system may revert to these automatic patterns.

Final Thoughts
Primitive reflexes shape early development, and integrating them helps children build strong neurological foundations for lifelong learning and regulation.
