Normal Developmental
     Milestones
 An emphasis on anticipatory guidance
         Ana Malinow, MD
Why we should teach
parents about development
Parents who understand their childᾼs
  developmental state, are more likely to
  have appropriate expectations.
Having appropriate expectations makes for a
  healthier relationship between parent and
  child.
Healthier relationships facilitate
  development.
Objectives
•   Principles of development
•   Primitive Reflexes
•   ᾿ Locomotion῀ : Gross Motor
•   ᾿ Manipulation῀ : Fine Motor
•   ᾿ Cognitive῀ : Language and Social
•   Behavior and Personality
Principles of
           Development
• A continuous process
• Sequence of development is the same, rate of
  development varies
• Not parallel
• Related to CNS maturation
• Involuntary movements give way to voluntary
  responses
• Occurs in cephalocaudal and proximal to distal
• Progresses from dependence to independence
Development Occurs in a
     Cephalocaudal
       Direction
Development begins
          in utero
Age         Responses/Reflexes
8 ½ wks     tactile stimuli (reflex arc laid down)
12 wks      sucking
24 wks      sound
26 wks      rhythmic breathing movements/
      controls body temperature
30 wks      pupilary light reflex
35 wks      grasp/spontaneous orientation to light
All primitive reflexes
  develop during gestation
and disappear by the 3 rd to
   6th month after birth
Primitive reflexes
• Tonic labyrinthine reflex
• Asymmetric tonic neck reflex
• Positive support reflex
Declining intensity of
primitive reflexes and
  increasing role of
definitive motor actions

     ᾿ Locomotion῀
Locomotion begins with
     head control

᾿ Manipulation῀
Fine Motor Development
Manipulation: Assessing the
 pincer grasp from 0-6m
•   NB            primitive
•   1m            primitive
•   2m            starting to lose

•   5m            palmar grasp
•   6m            hand-mouth-hand;
                  hand-to-hand
Manipulation: Assessing
 the pincer grasp 7-12 m
• 7m         thenar side, raking
• 8m         1 block in each hand
• 9m         radial-digital grasp;
             inferior pincer
• 10m        index finger isolation
• 12m        fine pincer
• >12m       letting go, stacking

         Problem solving
•   NB        visual exploration
•   4-6wks    smiles, fixes, follows
•   2m        imitates mouth movements
•   3m        anticipates feeds
•   5m        object permanence
•   6m        looks to floor when toy dropped
•   7m        grabs 2nd cube, drops first
•   8m        seeks object after fall (silent)
•   9m        uncovers hidden object under cloth
•   10m       isolates index finger

• Adolescence begins identity formation
  (idealistic)
• Adulthood completion of identity

Conclusion
• Development is a continuous process
• Sequence is always the same, rate varies
• Development does not run parallel
• Intimate relationship with CNS
• Generalized activity gives way to voluntary
  activity
• Cephalocaudal development
• Dependence to independence
