Common Newborn Reflexes

Home / Articles / Common Newborn Reflexes

Newborns are born with several natural reflexes—automatic, involuntary responses to stimuli—that help them survive, adapt, and develop.

Common Newborn Reflexes:

  • Rooting Reflex:
  • Trigger: Touching or stroking baby's cheek.
  • Response: Baby turns head towards the touch, opens mouth, and searches for nipple or food source.
  • Sucking Reflex:
  • Trigger: When an object (finger, nipple, or pacifier) touches baby's lips or inside of mouth.
  • Response: Baby instinctively sucks to facilitate feeding.
  • Moro (Startle) Reflex:
  • Trigger: Loud noises, sudden movement, or feeling of falling.
  • Response: Baby flings arms and legs outward, then quickly brings them back toward body in an embrace-like motion.
  • Grasp (Palmar) Reflex:
  • Trigger: Stroking or placing object in baby's palm.
  • Response: Baby tightly grasps the object.
  • Stepping Reflex:
  • Trigger: Holding baby upright with feet lightly touching a flat surface.
  • Response: Baby appears to "walk," making stepping motions.
  • Babinski Reflex:
  • Trigger: Stroking the sole of baby’s foot from heel to toes.
  • Response: Baby's toes fan out, and foot twists inward.
  • Tonic Neck Reflex (Fencing Reflex):
  • Trigger: When baby’s head is turned to one side while lying down.
  • Response: Arm on that side stretches out, opposite arm bends, adopting a “fencer’s” pose.

Significance:

  • Reflexes indicate normal neurological and developmental function.
  • Many reflexes fade as the baby matures (usually within first 6 months), replaced by intentional movements and skills.

If reflexes appear absent, exaggerated, or persist beyond the expected age, it's important to discuss this with your pediatrician.
