Primitive reflexes are the "movement programs" that organize fetal positioning, assist with birth, and lay the foundation for a child's coordination and emotional regulation. In this episode, Dr. Brittany and Dr. Jaimy dive into why these brainstem-driven survival responses are trending on social media—and why they are far more than just "fun" movements. They explore the critical link between a mother's nervous system in pregnancy and the integration of these reflexes in infancy. Whether you are curious about why your toddler is "clumsy" or why your infant only turns their head one way, this conversation provides a grounded, evidence-based look at how we can support extraordinary development through mindful movement and safety.
Main Topics Covered
What are Primitive Reflexes? Defining them as brainstem-driven survival programs that should naturally "blend" into development.
Survival vs. Integration: How these reflexes emerge in the womb to help with birth and then integrate so the higher brain (cortical brain) can take over.
The "Retained" Reflex: Why a reflex that stays active can lead to challenges with balance, attention, and emotional regulation.
The Mother’s Nervous System: How high stress or lack of safety during pregnancy can impact the baseline of the baby's nervous system.
Motor Skill Categories: A breakdown of uterine, transitional, neck, and postural reflexes.
The "Crawling" Debate: Why skipping milestones like crawling can signal a divergence in neurological development.
Behavior as Communication: Reframing "misbehavior" or "defiance" as signs of a nervous system stuck in fight, flight, or freeze.
The Importance of Movement: Why "floor time" and tummy time are essential tools for integrating reflexes and avoiding "container syndrome."
Key Takeaways
Integration, Not Disappearance: Primitive reflexes don't just "go away"; they are incorporated into more complex movement patterns.
Safety is the Refiner: For a baby to move out of survival mode and integrate their reflexes, their nervous system must feel safe and regulated (co-regulation).
Don't Move the Line: Developmental milestones (like crawling) are not suggestions; they are critical markers for normal neurological cross-patterning.
Patterns Over Pathology: Clumsiness or emotional outbursts are often expressions of an unintegrated nervous system rather than permanent personality flaws.
Tummy Time is Anything But Back Time: Supporting a baby's integration can be as simple as skin-to-skin contact, using a yoga ball, or letting them explore the floor.
