Until what age does the Moro reflex typically persist?

The Moro reflex, also known as the startle reflex, is an important primitive reflex observed in newborns. It usually emerges around 28 weeks of gestation and is a normal part of newborn development. Typically, the Moro reflex persists until about 2 months of age. After this period, the reflex gradually diminishes and typically disappears by the time the infant is around 4 to 6 months old. This timing is crucial to monitor as it indicates neurological development and the maturation of the infant's nervous system.

Recognizing that the Moro reflex is strongly present from birth and starts to fade around 2 months helps caregivers and healthcare providers assess the infant’s developmental milestones. Therefore, 2 months is the correct answer regarding when the reflex typically persists, highlighting its significance in evaluating newborn development.
