It's normal in infants due to their developing nervous extension of the big system. The reflex involves extension of the toe and fanning of other toes. Named after Joseph Babinski, it's a key assessment tool. Abnormal responses may suggest central nervous system damage."

The Babinski Sign

👣 Babinski Reflex in Infants Explained When the sole of a baby’s foot is gently stroked, their big toe bends upward and the other toes fan out — this is called the Babinski reflex. 🍼 ✅ Importance: Normal in newborns up to ~12–24 months. Shows healthy development of the nervous system. Disappearing as the brain and spinal cord mature. If it persists beyond 2 years, it may indicate a neurological issue. 🔍 Pediatricians use this reflex to check proper brain and spinal cord function in infants. |
