The parachute response is a protective reflex that emerges around 6 to 9 months of age and is expected to persist throughout life. This reflex is characterized by an infant extending their arms and legs when falling or when they feel like they are being dropped. It serves as a vital safety mechanism, allowing the child to react to potential danger and protect themselves from harm.

In contrast, the rooting reflex, which helps a newborn find food, typically disappears by 4 months of age. The Moro reflex, also known as the startle reflex, usually fades by 4 to 6 months. Similarly, the palmar grasp reflex, which involves an infant clasping an object placed in their palm, generally disappears by around 5 to 6 months. Therefore, the parachute response stands out as the reflex that not only persists beyond 6 months but continues to be significant for safety throughout development.
