  6. State of Arousal in Infants State Behavior of Infants Non-REM sleep REM sleep Drowsiness Alert inactivity Alert activity Distress Complete rest Occasional twitches; irregular and intermittent eye movements Occasional movements, but fewer than in REM sleep; eyes open and close;glazed look Eyes open and scanning; body relatively still Eyes open, but not attending or scanning; frequent,diffuse bodily movements; vocalizations Whimpering or crying; vigorous movements; facial grimaces; skin flushed Source: Ferber and Kryger (1995)

  8. MAJOR REFLEX REACTIONS IN NEWBORN INFANTS SURVIVAL REFLEXES: Serve obvious physical needs breathing sucking eyeblink rooting swallowing pupillary PRIMITIVE REFLEXES: Serve no obvious physical needs; may be vestiges of important reflex behaviors at earlier stages of human evolution moro tonic neck stepping grasping Babinski swimming

  9. Milestones of Motor Development

  10. Summary of Physical Development in the First Two Years • Cephalocaudal and proximodistal directions of growth • At birth the brain is 25% of its adult weight, the body only 5%. • By two years the brain is 75%, and the body 20% of adult weights. • Neonate is born with variety of reflexive behaviors. • Infant sleeps two times as much as adult. • Injuries claim lives of more children than all major illnesses combined.
