Physical Development
Primitive reflexes
Every individual is born with primitive reflexes, which are automatic
responses to a stimulus. There are a wide range of different reflexes
that an infant is born with, for many different purposes, enabling its
survival at a young age. These reflexes can include:
Sucking – There’s a rhythmic sucking on stimulation
Grasping – The toes of the child curl inward when their sole is
touched
Rooting – The head of the baby turns toward the direction
where their cheek may be getting stimulated
Startle/Moro – The sudden extension then flexion of the arms
Tonic Neck – The extension of the limbs on the face’s side of
the newborn’s body
