How long is the "doll's eye" phenomenon typically observed in a newborn?

The "doll's eye" phenomenon, also known as the Oculocephalic reflex, is typically observed in newborns and refers to the eye movements that occur when the head is turned. In this reflex, the eyes move in the opposite direction of the head turning, which is a normal response indicating intact neural pathways.

This phenomenon is generally observed in newborns and can last for around 10 days following birth. It usually diminishes as the infant's neurological system matures. Although the presence of the doll's eye reflex can be an important indicator of neurological function in newborns, it is usually not expected to persist beyond this time frame as the child develops more voluntary control over eye movements.

The indication that this reflex typically lasts for about 10 days aligns well with neurological development milestones, which makes this choice the most accurate in the context of newborn physiology and assessment.
