The Babinski reflex is considered normal in children up to how many years old?

Explanation:
The Babinski reflex is a primitive motor response that is normal in very young children because the corticospinal pathways aren’t fully myelinated yet. When you stimulate the sole, the toes fan and the big toe dorsiflexes. As the nervous system matures, this response changes to the adult pattern of plantar flexion. That maturation typically completes by about two years of age, so a positive Babinski is normal up to around two years old. If the sign persists after that, it can indicate an upper motor neuron problem.
