The Moro reflex typically disappears at about which age range?

• A. 3-5 months
• B. 6-8 months
• C. 7-9 months
• D. 10-12 months

Answer: (A)

The Moro reflex is a primitive startle response that appears at birth and is integrated as the nervous system matures. Its normal disappearance occurs by about three to five months of age, so the 3–5 month window is the typical time frame when this reflex should no longer be present. If the reflex persists beyond roughly six months, it can indicate delayed neuromotor development and warrants further evaluation. The later age ranges (6–8, 7–9, 10–12 months) are outside the normal window and suggest delayed integration.
