Examination of the baby’s cranial nerve function is often accomplished by observing spontaneous activity.
  • During crying, facial movement (CN VII) Cranial Nerve 7 is observed for fullness or asymmetry.
  • The quality and strength of the cry is a way of looking at (CN IX) Cranial Nerves 9 and (CN X) 10 function.
  • Sucking and swallowing assesses (CN V, VII, IX, X) Cranial Nerves 5, 7, 9, 10, and 12 because all of these cranial nerves are involved in this complex act.
  • Eye movements (CN III, IV, VI) Cranial Nerves 3, 4 and 6 can be assessed by using the vestibulo-ocular reflex (doll’s eyes maneuver).
  • When the head is turned, there is conjugate eye movement in the opposite direction.
  • Testing a baby’s behavior response to light (CN II) Cranial Nerve 2 and sound (CN VIII) Cranial Nerve 8 also adds to the cranial nerve exam.
  • Pupillary light reflex, corneal reflex, gag reflex and funduscopic exam are done in the same manner as the adult exam.
