Why does the Babinski reflex differ in adults and infants?
Babies don’t have full control over their nervous systems, so these reflexes are common and indicate healthy neurological function. As children grow, they get better control over their nervous systems. As a result, the Babinski reflex and other common reflexes seen in infancy disappear.
Is a positive Babinski normal in infants?
It is super normal in babies, and a sign that the brain and spinal cord (aka the central nervous system) are working together well. Again, in babies and toddlers, a normal Babinski reflex means the big toe flexes upwards while the other toes flare out once the foot is stroked from heel to toe.
At what age does a Babinski integrate?

What is a positive Babinski reflex indicative of?
The presence of the Babinski reflex is indicative of dysfunction of the CST. Oftentimes, the presence of the reflex is the first indication of spinal cord injury after acute trauma.
What does absent Babinski reflex mean?
The examiner watches for dorsiflexion (upward movement) of the big toe and fanning of the other toes. When this occurs, then the Babinski reflex is present. If the toes deviated downward, then the reflex is absent. If there is no movement, then this is considered a neutral response and has no clinical significance.[10]
Why does my 10 month old curl his toes?
