Moro Reflex

Definition

The Moro reflex is an infantile reflex normally present in all infants/newborns up to 3 or 4 months old as a response to sudden loss of support when the infant feels as if it is falling. It involves three distinct components - spreading out the arms, pulling the arms in, and usually crying.

Analogy

Imagine you're on a roller coaster and suddenly there's a steep drop. You'd probably throw your hands up and then clutch them to your chest while screaming. That's similar to what babies do when they experience the Moro reflex!
