Q

BREAST ANATOMY:

What is the BF function of using a wide gap and deep latch by baby?

A

Infant will form teat from nipple & much of areola, which reaches back of mouth. Flexible and elastic breast tissue facilitates optimal, comfortable lengthening of breast & nipple to facilitate this.

Q

INFANT FACIAL BONES: Describe function and location of hyoid bone. Discuss cartilage vs bone of hyoid. Why is hyoid so important in BF?

A

Hyoid cartilage provides attachment to tongue above, larynx below, epiglottis and pharynx behind.

Located in neck at level of base of mandible and above thyroid cartilage.

Develops from cartilage to bone during childhood.

Important in BF because extension of head will slide hyoid and tongue forward, while flexion of head will slide the backward.

Q

As a result of moulding (movement and overriding of the cranial bones at sutures and fontanelles) during birth & in utero, how can the bones be moved back into position after birth? Why is this important to BF?

A

By yawning, sucking and crying. Importatnt because the cranial nerves involved in BF (6/12) follow the sutures.

Q

Describe components of oral cavity of infant

A
  • small
  • tongue fills entire oral cavity at rest
  • taste buds primarily on tip of tongue; increased suckling occurs in response to sweet stimuli
  • lingual frenulum is fold of mucous membrane extending from floor of mouth to midline of under surface of tongue
  • lower jaw (mandible) is small and slightly receding
  • cheeks defined by buccinator and masseter muscles; buccal fat pads in cheeks help provide lateral stability for suckling pattern
  • labial frenum is membrane attaching upper lip to gum ridge
  • lips include orbicularis oris muscle
  • roof of mouth formed anteriorly by boney hard palate, and poseteriorly by mobile soft palate.

Q

Describe changes in oral cavity by 6-8 months of age.

A
  • enlarges
  • buccal fat pads resorb, creating cavity for mastication
  • in infant, larynx sits high in neck @ C1-C3 vertebrae - functionally separates respiratory and digestive tracts. This allows infant to breathe and suckle safely. By 2-3 years, larynx descends, with common channel in oral portion of pharynx for respiration and swallowing.

Q

Role of hard and soft palate

  • rugae
  • hard palate
  • soft palate
A
  • rugae of hard palate assist w positioning and stability of teat
  • hard palate provides resistance against which tongue compresses teat
  • stimulation of hard palate necessary to elicit sucking reflex
  • soft palate joins hard palate to appx. epiglottis until it descends at 3-4 mos. (This, plus size of tongue in oral cavity, is why infants are mostly nose-breathers.)
  • muscles of soft palate cause it to elevate during swallow, closing nasal cavity and allowing milk to enter oro-pharynx
  • hard & soft palate combined separate oral fr nasal cavity, allowing sealed compartment and creation of negative pressure during suckling.

Q

What does skin to skin (SSC) contact do?

A
  • triggers babys innate response (pre-programmed neurobehavior) which guides him to provide for own needs, eg seeking breast
  • prone position of baby on mom’s chest ensures positional stability, allowing baby to use arms to lift upper body and extend neck, before placing chin on breast prior to latching.
  • allows for sensory stimulation of smell, touch, warmth - cause oxytocin surges in mom which heats chest skin temp, triggers nipple erection and decreases maternal anxiety.

Q

What does a proper latch from the “instinctive position” look like?

A
  • a lot of areola/breast tissue beneath nipple taken into mouth, followed by nipple
  • neck slightly extended, chin indenting breast
  • nose free to breathe
  • oro-pharynx wide open to allow unhindered swallowing
57
Q

Describe the biological nurturing position and why it is important.

A

Mom semi-reclines with baby prone in close frontal contact w body.
This position promotes highest release of primitive neonatal reflexes (PNR) for pre-feeding response.

58
Q

Positioning: While Sitting

describe position

A
  • semi-recline in chair with feet up on a stool or something (reduce lower back strain)
  • baby’s head at height of natural fall of breast (beware of pillows lifting baby higher)
  • snuggle baby to chest, under breasts with baby’s chest in contact with lower, inside portion of breast [sensory impact]
  • mother supports baby across back, between shoulders, usually with palm of hand [stable base]
  • mom’s wrist or forearm supports baby’s head and neck using arm on same side as breast suckled (ie cradle hold); or cup formed between thumb and forefinger supports neck (cross cradle hold) [proximal stability]
  • baby’s head, neck, spine aligned (ie head not flex forward not twists in spine at neck or waist); one arm on either side of breast [midline symmetry]
59
Q

Positioning: Cradle Hold & Cross-Cradle Hold

How positioned?

A

Cradle: Semi-reclined, baby across chest and supported with arm on same side feeding.

Cross-cradle: Same, but baby held using opposite arm.

60
Q

Twin or Football hold

What types of women prefer this option?

A

Baby held under arm. Good for women w very large breasts.

61
Q

Positioning: While side-lying

Describe position

A
  • mom lying on side w lower arm tucked under head or pillow (safer co-sleeping position)
  • lay baby on bed, on side with upper shoulder facing mom [proximal stability]
  • baby’s lower arm cradles breast from underneath, upper arm free to move [midline symmetry]
  • baby’s chest and upper shoulder tuck under mom’s upper (unused) breast [sensory input]
  • mom supports baby across back between shoulders with free upper hand [stable base]
62
Q

Positioning: side-lying - benefits

A
  • mom can rest/sleep during feed
  • avoid sitting on painful perineum post delivery
  • avoid weight of baby on c-section wound
63
Q

What to NEVER to in providing proximal stability.

A

NEVER hold back of baby’s head at any time during positioning, latching and feeding

64
Q

What 7 checks to make for proper positioning?

A
  1. Is there adequate sensory input (chest to chest, baby held in firmly)
  2. Is there a stable base (support across back between shoulder blades)
  3. Is there proximal stability (neck & head supported but NOT held)
  4. Is there midline symmetry (neck and head aligned w spine; one arm on either side of breast)
  5. Is chin firmly applied to breast, nose free to breathe
  6. Is mom relaxed and well-supported
  7. Is mom’s baby-supporting arm held comfortably, with relaxed wrist and fingers
65
Q

Which cranial nerves provide the innervation for the rooting reflex? (4)

A

CN V
CN VII
CN XI
CN XII

66
Q

How is rooting reflex elicited?

A

By touch to cheek or near mouth

67
Q

Why is the rooting reflex so called?

A

Because it triggers:

  • turning toward stimulation
  • opening mouth (gape)
  • protrusion of and dropping of tongue ready to grasp breast
68
Q

Which cranial nerves provide the innervation for the sucking reflex? (4)

A

CN V
CN VII
CN IX
CN XII

69
Q

How is the sucking reflex elicited?
What happens when adequate teat is formed?
What about an inadequate teat?

A

tactile or chemical stimuli on hard palate

When an adequate teat has been formed, pressure will be exerted on palate by upper surface of teat eliciting this reflex.

When inadequate teat formed, can be seen as adaptive function - eg when baby unable to form teat d/t insufficient breast tissue in mouth,, won’t suck and therefore avoids nipple damage

70
Q

What are the characteristics of a well-latched baby (5) (Positioning and interaction with breast)

A
  • Nipple and much of areola and underlying breast structures drawn into mouth to form teat
  • Tip of teat (nipple) reaches within 3-5 mm of junction of hard and soft palate (at back of mouth)
  • Tip of tongue protrudes past bottom gum line
  • Lateral edges of tongue form a trough-like shape, cupping breast
  • Mouth will be wide open with both lips relaxed on breast and flanged outwards. Angle at corer of mouth should be at least 140 degrees.
71
Q

Mother may need to shape breast slightly to ensure proper latch. If needed, describe technique options

  • base of nipple position
  • “sandwich” areola position
A
  • Base: put pressure near base of nipple, at point where nose is pointing, causes nipple to tilt toward nose. As bottom lip firmly plants at edge of areola, the finger that is causing the tilting can then roll the nipple so it just brushes under, or folds under baby’s top lip.
  • Sandwich: One finger placed on either side of areola to “sandwich” breast and tile nipple to touch the top lip and offer underside of areola to baby’s bottom lip.
72
Q

Mom provides the POSITIVE PRESSURE in BF - how?

A

Milk ejection

73
Q

Baby provides the NEGATIVE PRESSURE in BF - how?

A

Negative pressure in baby’s mouth draws breast into position and maintains. Baby removes available milk when jaw and posterior tongue lowered creating further negative pressure in mouth, opening milk ducts and drawing milk into mouth. Baby’s gums compress milk ducts and create slight positive pressure.

74
Q

Where is the majority of milk stored in mammary gland?

A

Alveoli

75
Q

Describe the process for initiation of the milk ejection reflex (MER) (6 steps)

A

MER initiated:

  • physically by stimulation of nipple & areola (supplied by lower branches of 4th intercostal nerve)
  • nerve impulse travels to hypothalamus
  • this causes posterior pituitary gland to release oxytocin into blood stream
  • oxytocin travels via bloodstream to both breasts (recall that oxytocin receptors found on myoepithelial cells)
  • in response to oxytocin, myoepithelial cells surrounding alveoli contract, squeezing the alveoli, and
  • forces milk into ductal system toward nipple
76
Q

What happens to milk not removed by infant or by expressing?

A

Moves back up ductal system to alveoli once more.

77
Q

What factors stimulate oxytocin (5)

A
  • hearing a baby cry
  • thinking about baby
  • seeing photo of baby
  • prep to feed
  • being usual time baby feeds
78
Q

What factors inhibit oxytocin (4)

A
  • pain
  • embarrassment
  • anxiety
  • fear
79
Q

Ways to assist mom with MER (8)

A
  • repeat same pre-feeding/pumping activities and even thoughts each time
  • sit in same chair
  • look at photo of baby
  • think positive thoughts about baby
  • visualize milk flows, rivers, waterfalls
  • listen to recording of same relaxing music
  • gently massage or stimulate nipples
  • ensure privacy, empathetic support, and good pain relief if necessary for all mothers.
80
Q

How many mothers experience sensation with first MER?

How about subsequent MER’s?

A

First: 79%
Subsequent: rarely feel

81
Q

How MER might be described (3)

A
  • sharp momentary pain in breast
  • fullness or tightness in breasts
  • tingling sensation in breast

Sx associated with oxytocin release (other than MER) (2)

A
  • involution pain (postnatal uterine contraction)

- thirst

83
Q

Signs MER has occurred include (3)

A
  • drips or squirts of milk fr breast
  • change in suckling pattern to nutritive
  • gulping as swallows larger volume of milk transferred
84
Q

Define sucking vs suckling

A

Sucking - mechanical action within oral cavity to transfer fluid or provide comfort
Suckling - normal action of suck that occurs while at breast

85
Q

Describe order in which newborn’s reflexes mature (sucking, reflexes, coordination, etc) (5)

A
  • 15-24 weeks gestation in-utero: sucking demonstrated
  • 26 weeks +: lingual and gastric lipases present
  • 26-27 weeks: gag reflex present
  • 28 weeks: rooting reflex present
  • 28-37 weeks gestation: Coordinated and effective suck/swallow/breathe for nutritive purposes
86
Q

Describe the 4 steps of the “suck cycle”

A
  • Lower jaw opens, posterior tongue and soft palate descend, touching each other and creating maximum intra-oral vacuum
  • At this point, milk xfer to baby, assuming MER has been elicited
  • Jaw closes, posterior tongue and soft palate rise, intra-oral vacuum is decreased, and the milk bolus prepared for swallow
  • milk xfer is momentarily paused awaiting next cycle
87
Q

Describe teat/infant oral positioning during such cycle.

A

Tip of teat reaches w/in 5 mm of junction of hard/soft palate.
Nipple position varies by appx 1 mm during suckling.
Anterior tongue remains mainly flat during suck/swallow.

88
Q

Types of sucking: Stimulation

  • when used
  • describe (4)
A

Stimulation is initial suck pattern used.
Describe:
-appears as short, fast sucks of up to 2 per second
- seen when infant first latches, prior to MER
- milk ejection usually stimulated within a minute
- intra-oral vacuum greater during this pattern than nutritive sucking

89
Q

Types of sucking: Nutritive (AKA Expression)

  • when used
  • describe (4)
A

Used to obtain nutrition in presence of fluid.
Description:
- During MER when milk flow is high, sucking bursts will be long with infrequent pauses
- rate is about 1 per second
- during MER, sucks appear continuously, followed by immediate swallow
- as milk avail diminishes through feed, sucking bursts become shorter and pauses become longer

90
Q

Types of sucking: Non-nutritive

- describe

A

Spontaneous sucking in absence of anything being introduced into mouth, or sucking on something that will not produce liquid nourishment.

91
Q

Describe process of the swallow (4)

A
  • milk moved fr nipple, held momentarily by posterior tongue
  • then passes under soft palate
  • posterior tongue lifts, helping milk bolus move into oro-pharynx
  • epiglottis closes to protect airway and milk may be safely moved into esophagus to complete swallow.
92
Q

Describe baby’s breathing during the swallow.

A

Infant CAN NOT breathe during swallow. Breathes in during suck, and in or out during pauses between sucking bursts.

93
Q

Possible causes of poor latch (11)

A
  • Mom not supporting baby
  • Baby’s neck not extended
  • Baby’s mouth isn’t wide open to “deep” latch
  • Baby’s bottom lip did not contact breast first or contact point moved after contact
  • Baby’s nose is obstructed by breast tissue
  • Baby’s lips are turned under instead of flanged outwards - mom may not be able to see this
  • Cheeks are sucked in or dimpled when suckling
  • Mom experiences pain throughout feed
  • Baby comes off breast easily, or frequently
  • Baby does a few sucks then just waits (not always poor latch, but often)
  • Nipple is compressed or otherwise misshapen as observed immediately after baby detatches
94
Q

Results of poor latch for mom (5)

A
  • pain while feeding (not always!)
  • damaged nipples (not always!)
  • ineffective breast damage
  • reduction in milk supply
  • early weaning
95
Q

Results of poor latch for baby (5)

A
  • inefficient milk transfer - ALWAYS!
  • tires quickly or may feed adequately only during MER
  • failure to thrive; due to inefficient milk transfer and poor intake (may take few weeks, with baby doing well initially w milk from overabundant supply that accompanies secretory activation)
  • poor sucking habits which may be difficult to correct
  • premature weaning
96
Q

Possible causes of poor/uncoordinated suck in a well, full-term infant (10)

A
  • poor latch
  • maternal drugs
  • separation from mom- absence of skin to skin contact
  • birth trauma
  • oral insult, esp before BF established
  • suck confusion
  • oral infection
  • infant’s state (eg agitated)
  • anything which interferes with baby’s innate reflexes to latch and suckle (eg swaddling)
  • Abnormalities of face, mouth of pharynx (see later cards)
  • dysfunction in infant’s musculature, or cranial or peripheral nervous system affecting suck (eg Down’s, muscular dystrophy)
97
Q

Abnormalities of face, mouth or pharynx: High arched palate or “bubble palate” - describe how this could happen

A

Baby could b thumb-sucking in utero or just hold tongue in high palate, or push breast up into high cavity rather than allowing normal position between hard and soft palate.
Could also result from abnormality of tongue since tongue helps shape palate in utero.

98
Q

Abnormalities of face, mouth or pharynx: Ankyloglossia (tongue tie) - describe resulting problems

A

Prob: If baby cannot extend tip of tongue beyond bottom gum margin, will decrease efficiency of milk xfer and prob cause trauma to breast as he sucks.

99
Q

Abnormalities of face, mouth or pharynx: Micrognathia (small, receding chin) - describe how to ID & resulting effect

A

Observed: when mouth is closed, mandible will tuck back and up under maxillae, sometimes noticeable gap is present.
Effect: affects link and forward mvmt of tongue - baby may find it hard to grasp breast and maintain fleshy teat in mouth, so pay careful attn to ensuring chin is well-anchored to breast

100
Q

Breast Anatomy Abnormalities: Inverted Nipples

  • How to ID
  • Possible treatments
A

ID: Palpate nipple w thumb and forefinger - compress just behind base of nipple. Nipples which are severely inverted will retract and a thick core is felt under finger tips.
Tx: Everting device in late weeks of pregnancy to stretch. Nipple shield is an option, after secretory activation (colostrum does not transfer properly with nipple shield).

101
Q

Change in nipple protractility during initial and subsequent pregnancies?

A

Generally increase in protractility with each pregnancy and lactation.

102
Q

What are 2 likely causes of inhibited MER?

A
  • surgical trauma to branches of 4th intercostal nerve, which innervates nipple & areola (eg during breast reduction or other surgery using peri-areolar incisions)
  • psychological inhibition (eg anxiety, pain, embarrassment)
103
Q

Tx options for inhibited MER (5)

A
  • hold baby in SSC for 20+ mins before baby wants to feed
  • discuss and try to alleviate psychological barriers
  • ‘conditioning’ of reflex incorporating relaxation techniques
  • some women have successfully used oxytocin nasal spray
  • if only one side affected by surgery, stimulating MER on other side will cause it to function on both sides
104
Q

3 possible factors affecting milk xfer

A
  • insufficient milk production
  • severe engorgement - milk ducts become compressed and milk flow inhibited. Baby also has difficulty achieving good latch.
  • surgical trauma to lactiferous ducts, as will occur in reduction mammoplasty, etc.
105
Q

Discuss legal informed consent requirements as they relate to consultations.

A

Before commencing assessment seek mother’s permission. Must get informed consent before any assessment or intervention, and prior to reporting relevant info to primary care provider.

110
Q

Wolf and Glass’ 5-step consultation process: Step 5

A

COMMUNICATION OF RESULTS

  • reiterate findings & action plan for mom *be aware of language using - don’t blame!
  • review plans with mother to be sure they are agreeable and achievable to all parties *could have mom write down in own words the important points and actions used to achieve successful latch
  • document outcomes of assess & eval
  • communicate findings to key healthcare providers (according to moms consent). Clearly ID and refer items needing further medical eval.
111
Q

Step 1: Observation & Assess: Gather Info

- list 4 component parts

A
  • take complete hx (medical, personal, pregnancy, labor, birth, BF)
  • breast exam
  • baby assess
  • observ of BF
112
Q

Step 1: Observation & Assess: Feeding Observation: General Observation
- list 3 component parts (describe = later cards)

A
  • breast exam
  • global assess of baby
  • oral assess of baby
113
Q

Step 1: Observation & Assess: Feeding Observation: General Observation: Breast Exam
- describe complete assess

A

Assess breast for…

  • size, shape
  • nipple variation - normal? large, inverted, flat? infection/damage?
  • palpation of breast for appropriate stage of lactation (ie degree of fullness, presence of lumps)
114
Q

Step 1: Observation & Assess: Feeding Observation: General Observation: Global assess of baby
- describe complete assess

A

*Some can be done while infant in mom’s arms & during hx taking. Otherwise use exam table or a pillow on your lap.
Assess….
- general muscle tone: facial and body mvmts should be symmetrical & smooth
- color & respiration: observe healthy skin color, pink mucous membranes and moist lips. respirations should not be labored or audible.
- degree of nourishment: body fat stores present in face, abdomen, arms and legs
- physical symmetry: head, neck and shoulder symmetry

115
Q

Step 1: Observation & Assess: Feeding Observation: General Observation: Oral Assess of Baby
- describe complete assess

A
  • Baby on exam table or lap. Use clean, gloved finger to assess:
  • rooting and gape response: stroke baby’s face and see response. Check for symmetrical facial mvmts. Elicit gape response by stroking down midline of face, watching for gape & tongue mvmt forward to extend past bottom gum to lick finger. Observe tongue forming long trough down middle to curl up laterally.
  • lips moist, pink mucous membranes. Check for infections, ulcers, and observe labial frenulum adhesion point.
  • Mouth size of oral cavity: stretch cheeks slightly to observe cheek pads for oral infection; note lower jaw position closed under maxilla; check under tongue for tight/short frenulum (tongue tie); are there teeth?
  • tilt baby’s head back and visualize palate - should be evenly sloped & about as wide as avg nipple. Be aware of high palates, rounded only in anterior position or very narrow. Possible to see undetected cleft.
116
Q

Step 1: Observation & Assess: Feeding Observation: Natralistic Observation
- describe complete assess

A
  • Prep: Have mom BF usual way - no intervention, positioning and support the same. Ask her to share current knowledge and talk about technique as she assists baby to latch.
  • Observe: Listen to how mom talks to baby, noises baby makes. Observe baby’s reflexes and how mom responds to them. How comfortable is mom in position? Where is baby’s body in relation to mom’s? Is latch correct - position, indent, gape, nipple resting on top lip before going in mouth, deep latch?
  • Progression of BF: see next card
117
Q

Step 1: Observation & Assess: Feeding Observation: Natralistic Observation
- describe complete assess
CONTINUED
- describe progression of the BF

A
  • Observe sucking patterns - stimulation to nutritive, w/ audible swallows? Stay in stimulation pattern, or lapse quickly into non-nutritive and fall asleep?
  • Note jaw mvmts. Lower jaw should make “deep” mvmts, visible up to temporo-mandibular joint
  • How long was nutritive pattern sustained (w only brief resting pauses)? Normally, after period of nutritive suckling the pauses will be come longer w occasional smaller jaw mvmts and fewer swallows will occur. Cycle may be repeated during BF w/ milk ejections
  • As mom how it feels. Should be pain free, with exception of maybe ‘nipple stretch pain’ in very beginning - occurs as nipple and areola form into teat.
  • How is feed completed? Baby should fall asleep (sated) at breast, or come off contented or wanting more milk from other breast.
  • Note appearance of nipple at moment of release from baby’s mouth. Should look almost same as when left baby’s mouth. No ridges or ‘squashed’ appearance or white lines across it.
118
Q

Step 1: Observation & Assess: Feeding Observation: Elicited observation
- describe complete process of making adjustments

A
  • describe your observations to mom
  • adjustents to hers/baby’s positions & re-education about correct latch can be offered immediately so BF can proceed w improvement
  • further observation of BF may indicate further investigation or implementation of specific plan
119
Q

Optimal BF is NOT defined by (4)

A
  • one breast or two during BF session
  • how much time passes until infant has next feeding cue
  • whether infant sleeps through night, or time between feeds. Sleepy infants usually a warning sign, not a sign of satisfaction.
  • whether or not infant is “good”. May not have sufficient energy to draw mom’s attention if not crying, etc.

A

Use pages 57-68 of BE03, and print all out

124
Q

IBCLC must be sure these 4 things are happening with mom/baby at all times.

A
  1. Feed baby - ensure adequate nutritional intake - could mean alt feeding methods temporarily if BF not successful
  2. Ensure adequate/abundant milk supply
  3. Ensure today’s plan doesn’t make tomorrow more difficult (avoid quick fixes)
  4. Keep BF attempts calm and reinforce positive experience for mom & baby
125
Q

Possible causes of lack of rooting reflex and/or inadequate gape (8)

A
  • prematurity
  • birth trauma/asphyxia
  • sick infant
  • temp CNS depression from intrapartum medications
  • short/tight frenulum
  • holding back of baby’s head to force latch
  • baby’s cues are absent or being missed, body not touching mom, no positional stability, nipple not @ top lip, baby not given enough time to lick
  • confused baby from overstimulation of face
126
Q

Management options for lack of rooting reflex and/or inadequate gape (8)

A
  • medical review and tx of condition as necessary
  • prolonged SSC with mom
  • encourage biological nurturing positions to stimulate primitive neonatal reflexes (PNR) as BF stimulants
  • mom to lie in bed next to baby as he sleeps and place nipple at top lip, ready to trigger innate root response
  • drip drops of expressed milk on baby’s top lip while nipple is ready
  • maintain nutritional status via means other than sucking
  • multi-disciplinary approach and therapy as necessary
  • time for recover, maturation, re-learning
127
Q

Management options for shallow latch +/- ridged/damaged nipples (5)

A
  • instruct mom how to position baby and breast correctly
  • instruct mom how to elicit rooting reflex for good gape, and encourage patience
  • gentle encouragement
  • gentle massage to posterior tongue, allow finger to be sucked back to correct place on palate, using breastmilk reward
  • treat tongue-tie or oral thrush present
128
Q

Possible causes of gape w/o progression to latch and/or suckling (6)

A
  • overly full or edematous breast
  • nipple doesn’t stimulate hard palate, therefore suck reflex (eg inverted or flat nipple)
  • restrictive frenulum, tongue unable to come forward to feel breast and grasp (eg absence of cue)
  • tongue up, blocking infant oral cavity
  • oral hypersensitivity from aggressive suctioning
  • previous sucking on bottle teat or pacifier
129
Q

Possible management options of gape w/o progression to latch and/or suckling (4)

A
  • treat and soften breast approproately
  • tease nipple out; +/- “nipple puller”; position infant in sitting position to use gravity to assist in grabbing more breast tissue; ‘shape up’ breast tissue and hold until sucking well established; may benefit from nipple shield, but only after good milk flow evident
  • facial stimulation exercise prior to attempted BF - slowly stroke midline of face iwth emphasis on bottom lip to encourage tongue to come forward and grasp finger
  • eliminate all forms of non-nutritive sucking until BF well established
130
Q

Possible causes for difficulty maintaining suction - coming off breast frequently/easily (3)

A
  • poor positioning, esp. head turned toward shoulder, or nose blocked by breast tissue d/t flexed neck or baby’s head higher than natural breast level
  • weak muscle tone - non-congenital causes/underdeveloped
  • unusual palate shape, ankyloglossia (tongue tie), small or receding jaw
131
Q

Possible management options for difficulty maintaining suction - coming off breast frequently/easily (4)

A
  • instruct proper positioning techniques, esp. adequate neck extension to provide jaw indent into breast and tongue stability
  • fill baby’s mouth with breast tissue and assist with breast support and compressions during feed
  • medical review and tx; frenulotomy for ankyloglossia
  • upright (sitting) feeding positions may help; good for cleft problems
132
Q

Name the two anchor points for the lingual frenulum

A

floor of mouth & under tongue

133
Q

What two conditions must be met for frenulum to allow full range of mvmt of tongue?

A

Frenulum must be THIN and MOBILE

134
Q

Short/tight frenulums may cause the following BF concerns (6)

A
  • inability to grasp breast
  • sore/damaged nipples - often a compression line
  • reduced milk transfer
  • uncoordinated suck
  • tired baby
  • undernourished baby
135
Q

Possible management options for short/tight frenulum (2)

A
  • frenotomy by trained health professionals…mom encouraged to BF immediately after
  • young baby will adapt to the extra tongue mobility quickly. Older baby may need tongue exercises to help focus tongue mvmts
