Normal Infant Feeding Development Newborn-6 months Flashcards

1
Q

caregiver-infant dyad

A
  • things to think about as we work with this demographic
  • role of the caregiver in the feeding: maternal supply, breastfeeding, role of the father, balancing bottle and breast, return to work
  • 4th trimester: 1st 3 months of life

Q

feeding skill development

A
  • impacted by overall development (cognitive, physical-gross and fine)
  • also impacted by sensory experiences (neural pruning)
  • medical (digestive, airway, GI, allergies)
  • psychosocial development: emotional regulation, cognitive development, speech and language development
  • family dynamics, cultural norms
  • by 4-6 months feeding is solely a learned skill as early reflexes integrate
  • look at feeding and oral motor skills within the context of the whole body
  • everything is connected

Q

tone and motor development and impact on feeding: stability and mobility

A
  • changing interactiof stability and mobility as children age
  • mobility develops from a proximal base of stability, moving toward more distal control
  • refined development of distal oral motor skills is affected if proximal stability is an issue
  • oral stability is dependent upon development of neck and shoulder girdle stability, which are dependent upon trunk and pelvic stability
  • the jaw is proximal to the distal lips, cheeks, and tongue

Q

stability

A
  • external more dependent on external support early on in development and around 6 months
  • less needed as the child approaches 12 months in typical development where more internal control and stability is developed

Q

sensory development and feeding

A
  • normal development of the infant’s sensory systems has a major impact on oral sensorimotor skills
  • mouth and hands have the highest number of sensory receptors per square inch of any other part of the body
  • sensory receptors of the mouth are the earliest to emerge in fetal development
  • early taste exposures com from mother’s diet which influences taste of breastmilk
  • newborns pruning helps “engrain” pathways about touch, taste, vestibular input
  • early tactile experiences and mouthing activities provide the infant with abundant oral sensory input

Q

“as the brain develops, sensory inputs pertinent to feeding extend into the midbrain, cerebellum, thalamus, and cerebral cortex. these developmental processes allow…”

A

“…the older infant and young child to gain competence in the evaluation of the physical character of food and ability to manipulate and swallow it.”

85
Q

suckling

A
  • from reflexive to volitional from 3-6 months
  • by approximately 3 months infant suckle transitions from reflexive to volitional behavior
  • sucking pads still provide positional stability for tongue and nipple but they are starting to disappear
  • slowly starting to transition from suckle to suck closer to 6 months
86
Q

mechanics of sucking

A
  • in newborns –> jaw is stable base for movement of tongue lips and cheeks
  • cheeks are passive support help with efficient sucking
  • lips + tongue = anterior seal and stabilize intraoral position of nipple (breast or bottle)
  • tongue forms central groove and stabilizes the nipple and helps direct fluid posteriorly for swallowing
  • tongue compresses nipple, positive pressure created expels the liquid
  • jaw and tongue drop downward during sucking and create negative pressure (intraorally –> suction) and it pulls fluid into the mouth
87
Q

sucking

A
  • downward jaw movement is rhythmical, enlargers oral cavity
  • facilitates generation of suction
88
Q

breastfeeding

A
  • olfactory system
  • visual system
  • positioning
  • supports physiological flexion
  • supports head/neck control
  • infant-caregiver bond for psychosocial development
  • different oral motor patterns than bottle feeding
89
Q

breastfeeding: visual system

A

color and size of areola

90
Q

breastfeeding: positioning

A

ventral surface bearing and posterior breathing (will define more)

91
Q

breastfeeding: different oral motor patterns than bottle feeding

A
  • different latch between bottle vs. nipple
  • sucking pressures
  • position and action of the tongue during sucking
  • rate of sucking and the pattern of milk flow
92
Q

breastfeeding vs. bottle feeding

A
  • nipple + underlying and surrounding breast tissue is elongated in the mouth by suction created in the infant’s mouth
  • nipple extends to where the hard and soft palate meet
  • lateral borders of the tongue cup around the nipple and form a central groove
  • milk expression and propulsion occurs via rolling action of the tongue from underneath the nipple
  • negative suction + positive compression work together synchronously to maintain milk flow and position of the nipple
93
Q

breastfeeding process

A
  • rooting reflex is initiated
  • bring baby to chest to ensure adequate latch (deep latch)
  • infant suckles for about 1-3 minutes (NNS) before milk ejection “let down” reflex occurs
  • rates of NN and nutritive sucking vary during breastfeeding
  • nutritive sucking is a slower rate (1 suck per second)
94
Q

breastfeeding process: rooting reflex is initiated

A

tactile stimulation of breast nipple to infant mouth

95
Q

breastfeeding process: infant suckles for about 1-3 minutes (NNS) before milk ejection “let down” reflex occurs

A
  • NNS occurs in short burst at a rate of up to 2 sucks per second prior to let down
  • increased flow rate during let down
  • suckling/sucking rate during let down is high and increased coordination is needed by infant for quicker SSB coordination
  • cough/choke or disorganized feeding pattern will be noted if let down or variable flow rate isn’t tolerated
  • after let down, the rate of nutritive sucking decreases to a rate similar to that seen in bottle feeding (1 suck per second)
96
Q

breastfeeding process: rates of NN and nutritive sucking vary during breastfeeding

A

NN occurs in short burst at a rate of up to 2 sucks per second, most often prior to let down

97
Q

normal infant anatomy that supports feeding

A
  • infants tongue is large in oral cavity, creates central tongue groove to create negative pressure
  • pharynx of infant
  • larynx descends in the first year of life to accommodate communication
  • oral motor components for successful feeding: lips, jaw, tongue, buccal mucosa, hard and soft palate
98
Q

normal infant anatomy that supports feeding: pharynx of infant

A
  • hyoid high neck
  • less laryngeal elevation during swallow
  • pharynx is gentle curve from nasopharynx to distal pharynx (adults ~ 90 degree angle)
99
Q

other things to consider: swallowing begins in utero

A
  • after birth infant needs to learn coordinate SSB
  • feeding involves ability to engage in physiologically and behaviorally challenging task, organizing oral movements, coordinate breathing with swallowing, and regulating depth and frequency of breathing to maintain physiological stability
100
Q

central pattern generators (CPGs)

A
  • the central patterning of aeroingestive behaviors include volitional and reflexive control mechanisms, and benefit from sensory feedback to modify the spatiotemporal organization of the feed sequence to ensure safe swallow
  • primarily composed of adaptive networks of interneurons that activate groups of motor neurons to generate task-specific motor patterns
101
Q

central pattern generators (CPGs): think of it as a closed loop system

A

with synchronized sucking, swallowing, breathing, esophageal function with feedback occurring to stop, delay, or maintain sucking

102
Q

development of nutritive sucking: typical feeding (term infant without comorbidities) has…

A

104
Q

infant swallowing thoughts

A
  • the mature swallow –> voluntary oral-preparatory phase, a voluntary oral phase, and involuntary pharyngeal and esophageal phases
  • the infant swallow does not have a voluntary oral-preparatory in early infancy but is otherwise similar but more rapid
  • has natural airway protection give anatomy
105
Q

pharyngeal phase, laryngochemoreflexes in infants

A
  • primary sensory mechanism for defending the airway from the aspiration of liquids
  • usually containing both parasympathetic components, such as apnea, bradycardia, and laryngospasm, and sympathetic components, such as systemic hypertension and blood flow redistribution
  • LCR is mainly present in newborns and infants, with even more robust and prolonged responses occurring in fetuses and premature infants
  • the reflex is thought to be largely a feto-protective reflex present to not only prevent aspiration during birth but also during the immediate postnatal development period
  • with age, maturation of neural circuitry within the brainstem allows for progression of the primitive LCR from prolonged apnea and glottic closure to a cough reflex, which also serves to protect the airways by expelling unwanted substances
106
Q
