nursing care directed by cultural aspects adn respects the individuals differences
Anticipatory guidance
educating parents and caregivers about what to expect int he next phase of development
purpose is to give parents tools
Solitary play
Does not share with others or directly play with others
Breast milk includes
LActose, lipids, polyunsaturated fatty acids, amino acids
Contribute to myelination of nervous system
Colostrum
First 2-4 days - thin waterly yellowish fluid that is easy to digest, high in protein and low in sugar and fat.
Foremilk
Milk that collects in lactiferous sinuses, which are small tubules serving as reserviours for milk located behind mipples
Let-down reflex
Responsible for release of milk from reservoirs.
When baby sucks, oxytocin is released and causes sinuses to contract which allows milk to let down into nipples
Why is cows milk bad for infants?
Not adequate balance of nutrients
May overload renal system with too much protein, sodium and minerals
Why is tounge extrusion reflex important when does it dissapear?
necessary for sucking to be an automatic reaction when nipple placed in mouth
dissapears at 4-6 months
What foods to avoid in infancy?
Honey
Eggs and meats
Excessvie fruit juice
Popcorn, hard foods, grapes
Citrus, strawberries, wheat, cows milk, eggs
Colic
resolves by

Inconsolable crying that lasts 3 hours or longer per day for more than 3 weeks and no physical cause
usually resolves bt 4 mo
avg baby 2.2 hours a day
States of consciousness
(6)
Deep sleep: Eyes closed, no movment
Light sleep: Eyes closed, Rapid eye movement, irregular movmeents
Drowiness: Eyes closed or half
Quiet alert state: eyes open, body calm
Active alert state: eyes open, body movements
Crying: cries or screams, difficult to gain attention
As the neuro system matures and myelination of the spinal cord continues, reflexive behavior is replaced with
and primitive reflexes disappear and what reflexes develop?
Purposeful action
Protective
Primitve reflexes are
Which ones are present at birth?
Subcortical and involve whole body response
Moro, root, suck, asymmetric tonic neck, plantar and palmar grasp, step and babinski, startle reflex
Protective reflexes are
when do these reflexes develop?
gross motor and related to maintenance of equilibrium
-Righting - occurs when neck muscles strengthen, allowing to maintain normal position in relation to body
and parachute reactions tilted and baby extends arms as if to break a fall
develop around 6 months
The lack of what immunoglobulin is mucosal lining contributes to frequent infections?
IgA
PROTECTIVE REFLEX
What is neck righting?
When does it start?
Neck keeps head in upright position when body is tilited
starts at 4-6 months and persists
PROTECTIVE REFLEX
What is Parachute (sideways)
Protective extension with arms when tilted to the side in a supported sitting position
6 monhts - persists
PROTECTIVE REFLEX
Parachute (Forward)
Protective extension with arms when held up in the air and moved forward. Infant reaches forward to catch him/herself
6-7months - persists
PROTECTIVE REFLEX
Parachute (backward)
Protective extension with arms when tilited backward
9-10months - persists
The presence of natal or neonatal teeth may be assoc with
other birth anomalies
Primary teeth began to emerge at what age
What are first teeth to appear

Lower central incisors followed by upper central incisors
Amylase (digest complex carbs) and lipase (fat digestion) is deficient and do not reach adult levels until
5 months
DEVELOPMENTAL THEORIES FOR NEWBORN AND INFANT
What is Erikson developmental theory
**Trust VS Mistrust (birth - 1yr)
Caregivers respond to infants basic needs. This creates sense of trust
As nervous system matures infants realize they are separate beings. Infants eventually learn even if gratification may be delayed it will eventually be provided
DEVELOPMENTAL THEORIES FOR NEWBORN AND INFANT
What is Piaget developmental theory
4 substages and ages
ownership develops 18-24 mo (MINE!)
Sensorimotor (birth - 2years)
Substage 1: use of reflexes (birth - 1 mo)
Substage 2: Primary circular reactions (1-4mo)
Substage 3: Secondary circular reaction (4-8mo)
Substage 4: COordinate of secondary schemes (8-12mo)
DEVELOPMENTAL THEORIES FOR NEWBORN AND INFANT
Piaget theory
Sensorimotor -
Substage 1
Substage 2
Substage 3
Substage 4
Sensorimotor - Uses senses and skills to learn about world
**Substage 1 **- Reflexive sucking bring nutrition, begin to gain control over reflexes and recognize objects, odors, sounds
Substage 2 - Thumn sucking, Imitiation begins, Object permanance begins, infant shows affect
**Substage 3 **- Repeats actions to get results
Substage 4 - Coordinate previously learned schemes wtih learned behaviors. Shake rattle, crawl. Anticpiate events, assoc symbols with events (waving goodbye when leaving)
DEVELOPMENTAL THEORIES FOR NEWBORN AND INFANT
