Rooting
Infant reflex: happens when something is placed in the hand, and they grasp the item and hold very well, almost enough to support their own weight
gripping/ grasping
Infant reflex: similar grasping but with the feet, happens when you stroke the inner or outer foot, inner sole being stroked means the baby will curl their toes, but if the outer sole is stroked the baby will spread toes
toe curling
Infant reflex: sudden noise or movement provokes the response; they will act very startled, open their eyes wide, throw their hands and arms into the air, throw legs out then cry; and then they will spread their toes
