The moro reflex typically disappears by what age?

The Moro reflex, also known as the startle reflex, is a reflexive response observed in newborns. It usually manifests when an infant experiences a sudden loss of support, resulting in a characteristic flinging of the arms outward followed by the pulling them back in. This reflex is part of normal neurological development.

The Moro reflex typically persists until around 4 months of age. By this time, most infants will begin to have more coordinated movements and will start to inhibit the reflex as they develop greater muscle control and stability. Its disappearance at around this age reflects normal neurological maturation, as the infant becomes more adept at processing stimuli and responding without relying on reflexive actions.

Understanding the timeline of reflexes is crucial in pediatric assessments, and recognizing the expected age range for the Moro reflex helps in identifying normal development markers or potential neurological concerns. Therefore, identifying 4 months as the age when the Moro reflex typically disappears is rooted in established developmental milestones.
