[Sub-Stage] 1 Simple Reflexes [Age] Birth-6 weeks [Description] 
"Coordination of sensation and action through reflexive behaviors".[25] Three primary reflexes are described by Piaget: sucking of objects in the mouth, following moving or interesting objects with the eyes, and closing of the hand when an object makes contact with the palm (palmar grasp). Over the first six weeks of life, these reflexes begin to become voluntary actions. For example, the palmar reflex becomes intentional grasping.[26]
