2. INTRODUCTION
The pediatric age group ranges form 0-18 yrs i.e. from the day of
conception to the 18 yrs of age .
They are :
 Prenatal period :From conception to birth
 Neonatal period :Birth to four weeks
 Infancy period :Four weeks to 1 year
 Toddler period :From 1-3 years
 Preschool period :3-6 years (early childhood )
 School period :6-12 years( late childhood )
 Adolescence :From puberty to beginning of adulthood (13-18 years)

Development in Infancy

4. Development follows an orderly, step-by-
step sequence in three different patterns:
Cephalo-caudal development is a “head-
to-foot” pattern. Prenatally and at birth
the newborn’s head is proportionately
larger; development continues
downward(for e.g. shoulders, middle trunk
and so on)
Head area : top parts of head eyes and
brain grow faster than the lower jaw
Motor development also follows Cephalo-
caudal development principle
• see objects before they can control
their torso
• Use hands long before they crawl and
walk

5. Proximal-distal (proximodistal) development
is an “inward-to-outward” pattern.
Development starts at the trunk of the body
and moves further outward.
Simple-to-complex development is a pattern
relating to the difficulty of tasks. Babies start
with simply eating and sleeping and progress
from there. Tasks involving a combination of
motions is more complex.
