4. Not all babies develop at the same rate.
Growth and development do not follow a timer, but are
greatly affected by external factors!
Development is non-linear. Patterns of physical,
emotional/social and intellectual stages will overlap.
“cross-influence” or interdependence.
5. Growth: height, weight, proportion
Sensory: sight, hearing, taste, touch, smell, and vocal
abilities
Motor Skills
6. Growth is the most rapid during the first year of life!!
Week #1 Week #52
7. Head to Foot
Growth begins with the head, and extends to the torso,
and eventually shoulders, arms, and legs.
Near to Far
Development starts at the trunk of the body and moves
outwards (learning to roll over, then crawl, walk)
Simple to Complex
Baby will transition from simple to complex tasks.
Slowly, this allows the baby to fulfill their own needs.
8. Slight weight loss immediately after birth
Triple their weight in the first year!
Gain = 1-2 lbs for the first 6 Months
Average Weight = 20-22 lbs at 1 year
Physical Activity, Eating Habits
And Heredity.
Weight Gain is a “good health”
Indicator in newborns.
9. Height is more “slow and steady” vs. Rapid weight
gain
Average at Birth = 51 cm
1 year = 76 cm
Heredity has a greater
affect on height than
weight.
10. Proportion - the size relationship of one thing to
another.
Proportionally: Large head and torso, and tiny limbs,
vs. Adults with larger limbs
Large head = rapid brain
development!
½ your total head growth
occurs before age 1.
11.
12. No light in the uterus = minimal vision development
Uncoordinated muscles, “googly eyed”
Eyes are often closed
14 days = Can see 7 to 10 inches away
2 Months = develop depth perception, “see in 3-D”
3.5 Months = Normal Vision!
Eye-hand coordination
13. Hearing begins to develop long before birth
At birth babies can tell sound direction
Respond to tone, not meaning
Hearing difficulties = trouble
speaking and listening
Hearing tested by 6 Months
14.
15. Amniotic fluid prevents sense of smell
At birth – responds most to unpleasant odours
First few days – recognize familiar smells (Mom, Dad)
Sense of taste develops quickly
Differentiate between sweet,
salty, sour and water soon after
birth.
Preference to sweet.
16.
17. Changes in throat, tongue, teeth and mouth allow
new foods, noises, cries and sounds
Over time allows for “distinctive cries”
Vowel sounds come first, but teeth are needed for
others
Full words usually come after 1 year.
Oral growth also allows for new foods/solids
18. 6-7 Months = primary teeth (first set)
Teething - teeth forcing their way up through gums.
Painful, swelling, bleeding, drooling
Cranky, restless and wakeful
2-10 days per tooth, occurs over 2 years.
What Helps?
Teething ring, ice, cold liquids,
commercial meds, chewing.
19. Motor Skills – Abilities that depend on the use and control
of muscles.
Very dependent on physical growth, but affected by social
and intellectual as well.
Head to Foot
1 Month – lifting head
3 Months – lifting chest
4 Months – sit with head steady, rolling over
5 -7 Months – reaching, pulls self up, “squirming”
8-10 – crawling, walks when lead, picking up objects
