What is indicated by the Babinski reflex in infants?

The Babinski reflex is a normal response observed in infants when the sole of their foot is stroked, causing the big toe to extend upwards and the other toes to fan out. This reflex is a sign of proper neurological function in newborns, as it indicates that the pathways in the nervous system are intact and functioning appropriately. During early infancy, the presence of the Babinski reflex is expected and is a part of the typical developmental milestones.

As infants grow and their motor skills develop further, this reflex gradually disappears, usually before the child reaches the age of two. Its presence is an important indicator for pediatricians and child development specialists, as it helps assess the functioning of the central nervous system.

In contrast, other options suggest that the reflex may indicate abnormalities or issues (such as medical attention being needed or motor development delays), which is not true for typical cases—therefore, those would not accurately describe the significance of the Babinski reflex in newborns.
