G+D infant Flashcards
growth
chronological age
increase in physical size
development
continuous, orderly series of conditions that leads to activities and patters of behavior
measured by observation
patterns of G+D
predictable, universal and basic, individual differences
directional and sequential trends
directional trends
cephalocaudal
proximodistal
differentiation
sequential trends
stages, critical periods, positive and negative stimuli
prenatal period
geminal: conception - 2 wk
embryonic: 2 - 8 wk
fetal: 8 - 40 wk (birth)
infancy
neonatal: birth - birth - 28 days
infancy: 1 mo - 12 mo
early childhood
toddler: 1- 2 yrs
preschooler: 3 - 6 yr
middle childhood
6 - 12 yr
late childhood
prepubertal: 10 - 12 yrs
adolescences: 13 - 18 yrs
G+D importance
anticipatory guidance - predict child and prepare parents
healthy habits
gain understanding of reasons behind illness
weight
10% initial loss after birth because of hormone withdrawal, loss of ECF, poop and pee, limited food intake (small stomach)
rapid growth: about 1 oz/day until 6 mo, double weight by 6 mo, tripple by 1 yr
height
increase 1 inch/month until 6 mo
increase 50% by 1 year
head
0.5 inches/month for first 6 mo
closure of fontanels: 2, assess for intracranial pressure and hydration, posterior closes 6-8 wk, anterior closes 12 -18 mo for brain growth
respiratory
abd breathers, rate slows
heart
rate slows, paradoxical pattern increases with inspiration and decreases with expiration
blood pressure
fluctuate but generally systolic rises as LV pumps better
hemopoietic system
fetal hemoglobin till 5 mo - physiologic anemia
maternal iron stores diminish at 5 - 6 mo
digestive system
immature at birth, function ~3 mo
drooling common bc poor coordinated swallow reflex
amylase and lipase (4-6 mo)
solid food not well tolerated, not broken down
coordination of sucking, swallowing, and teeth eruption to prep for solid food (4-6 mo)
1st tooth eruption (5-6 mo)
taste: well developed, avoid bitter and sour for sweet
urination
kidneys immature and cant concentrate urine
proportion of fluids increases risk of dehydration
endocrine
e imbalance, fluid imbalance, glucose [], aa metabolism, stress
thermoregulation
shiver after first few months
adipose tissue
adjust to cold by 6 mo
need multiple layers
vision
birth - 1 mo: follow object to midline, 8 - 10β
2 mo: lift and look
3 mo: faces!, associate visual stimuli and event
4 mo: hand regard, follow past midline, recognize, follow parents
6 mo: directed reach, depth perception
10 mo: object permanence
hearing
discrimination to mothers voice at birth and familiar sounds to soothe
3-6 mo: localize sound, understand few words
6-12 mo: first meaningful word
12 mo: hear and follow simple command
motor development - gross
random, diffuse, uncoordinated; reflexes carry out bodily functions and responses to external stimuli
head control
1 mo: marked head lag
3 mo: hold up
4 -6 mo: well established head control
