Objectives

Identify key development milestones of the newborn through late infancy

2

-Birth to 12mths
-Slight overlap with neonate (birth to 4wks)
-Rapid physical growth
By end of year….
-Manipulation of objects
-locomotion
-Rapid maturation
-Quite a bit of the CNS

Infancy

3

Increase in length by 50% or greater
-Fig 4.1, p93- good pictures of growth

Height

4

Typically, birth weight triples by end of first
year
-Fig 4.1, p93- good pictures of growth

Weight

5

HR @ birth- 120 to 140 bpm/ at 1 yr.- 80 to 100 bpm
BP @ birth- 80/55; at 1 yr.- 95-100/55.

Vital Signs

-Early Infancy
-Middle Infancy
-Late Infancy
-Infancy Transition

Subdivision of the 1st year in 4 time frames

7

Birth to 3mths

Early Infancy

8

4-6mths

Middle Infancy

9

7-9mths

Late Infancy

10

10-12mths

Infancy Transition

11

Each time frame looks at:

Gross Motor
Fine Motor
Oral-Motor
Cognitive-Language
Personal-Social

12

-Lifts head in prone
45 degrees (1-2mths)
90 degrees (2-3mths)
-Total head lag in pull-to-sit (NB)
Decrease in head leg (1-3mths)

Gross Motor

13

-Hands closed most of the time initially
Begin to open more (1-3mths); prereaching & ulnar grasp
-Sucking of hands

Fine Motor

14

Suckling pattern
Coordinates suck, swallow, and respiration

Oral- Motor

15

Cries, coos, chuckles, vocalizes when not crying

Cognitive-Language

16

-Cries to communicate
-Calms to face or voice
-Visual tracking
~NB- not across midline
~ 3mths- across midline

Personal-Social

17

All primitive, ATNR, TLR, palmar grasp, stepping, supporting
Rolls prone (side) to supine, supine (side) to prone (3-6mths)
Full prone extension (6mths)
Lifts head and helps w/pull-to-sit (5mths)
Hands and feet to mouth
Sits propped (5-6mths)
Supported standing w/weight bearing

Middle Infancy 4-6 Gross Motor reflexes appear?

18

-Midline play with both hands (4-5mths)
-Grasping of objects placed in the palm (4mths)
-Primarily ulnar & palmar grasp, reaches, and rakes

Middle Infancy 4-6 fine Motor reflexes appear?

19

-Spoon feeding (4mths)
-No upper lip activity
-Disassociation of lip, jaw, tongue with true sucking
I-ncreased upper lip activity (5-6)

Middle Infancy 4-6 Oral reflexes appear?

20

-Infant will attempt to continue interesting experiences (secondary circular reactions)
-Increase in sounds
-Babbling begins; also attempting “da da”

Middle Infancy 4-6 fine Cognitive- language reflexes appear?

21

Early play
Infant shows delight; laughs and chuckles

Gross Motor

23

Radial palmar grasp (7)
Lateral pincer grasp (8-9) and voluntary release

Fine Motor

24

Eats well with a spoon (7)
Initiation of solids; uses munching patterns (7-9)

Oral-Motor

25

Babbles vowel-consonant sounds
Use of secondary circular reactions to control the environment
Object permanence develops

Cognitive-Language

26

shows anger and fear
Will be upset if caregiver leaves
Early signs of caregiver attachment
Becomes an “emotional being”

Personal-Social

look up

32

Stranger anxiety

Transitional Infancy 10-12Personal-Social

36

failure to fall within the normal ranges of milestone development

Developmental Delay-

37

an infant may be in the low range of milestones, but the performance of the task is poor

Abnormal Development

38

8mth old baby born at 28 weeks (40-28 = 12)
8mths- 3mths = 5mths old adjusted age for associated normative values
Considered until the infant is 2yrs. old
