Definition:
The "Moro reflex" is a natural reaction that some babies have, especially when they are very young (usually up to about 3-4 months old). When a loud noise occurs or if they feel like they are falling, babies will suddenly stretch out their arms and legs, and then quickly pull them back in. This reflex is a way for babies to protect themselves.
The "Moro reflex" is an important part of how infants react to sudden stimuli.
