Study Notes
Infant Reflexes
-
Primitive Reflexes: These reflexes are present at birth and disappear as the baby develops.
- Rooting Reflex: Appears at birth and disappears by 4 months. Triggered by stroking the cheek or mouth; baby turns towards the stimulus.
- Sucking Reflex: Appears at birth and disappears by 4 months. Initiated by placing something in the baby's mouth, causing them to suck.
- Moro Reflex (Startle Reflex): Appears at birth and disappears between 4-6 months. A sudden noise or movement triggers the reflex, with arms extending outwards and back like a hug.
- Palmar Grasp Reflex: Appears at birth and disappears around 5-6 months. Touching the palm causes the baby to grasp tightly.
- Plantar Grasp Reflex: Appears at birth and disappears around 9-12 months. Touching the sole of the foot causes the toes to curl downwards.
- Babinski Reflex: Appears at birth and disappears between 12-24 months. Stroking the outside of the foot causes the big toe to raise, while the other toes fan out.
- Asymmetrical Tonic Neck Reflex (ATNR): Appears at birth and disappears between 4-6 months. Turning the head to one side causes the arm on that side to extend and the opposite arm to flex.
- Stepping Reflex: Appears at birth and disappears after about 2 months. Holding the baby upright with feet touching a surface elicits a stepping-like movement.
-
Postural Reflexes: These reflexes are associated with posture and balance, developing later than primitive reflexes.
- Parachute Reflex: Appears between 6-8 months and persists throughout life. When falling, the baby instinctively extends their arms and legs to brace for impact.
- Landau Reflex: Appears between 3-4 months and disappears around 12-24 months. This reflex involves holding the body in a straight line against gravity.

- Swimming Reflex: Appears at birth and disappears between 4-6 months. The baby instinctively makes swimming-like movements when lying face down in water.
- Babkin Reflex: Appears at birth and disappears by 3-4 months. Applying pressure to the palm of baby's hand creates a mouth opening.
- Crossed Extension Reflex: Appears at birth and disappears by 1-2 months. When a leg is lifted, the opposite leg extends as well.
- Placing Reflex: Appears at birth and disappears by 2 months. Touching the sole of the foot to a surface causes the baby to lift the leg.
