BLNST study plan

BLNST · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Maternal and Infant Anatomy and Physiology

  • Map the gross anatomy of the mammary gland - lobules, ducts, ampullae, nipple, areola, Montgomery glands, suspensory ligaments - and draw a labeled diagram from memory

  • Trace the endocrine sequence of lactogenesis I and II, naming the hormones, their source, and the timing of each transition

  • Explain the milk ejection reflex arc from nipple mechanoreceptor to oxytocin release and myoepithelial contraction, including inhibitors of let-down

  • Compare colostrum, transitional milk, and mature milk in volume, energy density, protein, immunoglobulin, and oligosaccharide content

  • Describe infant oral anatomy (tongue, palate, jaw, fat pads) and the swallow–breathe–suck coordination sequence in the newborn

Your checkpoint

A one-page hand-drawn lactation anatomy and physiology diagram with 15 labeled structures and a written hormone timeline, self-graded against your notes for missing items

Week 2

Normal Breastfeeding and Lactation Management

  • Demonstrate and document the four breastfeeding positions and the components of a deep asymmetric latch in a written step-by-step protocol

  • Calculate expected 24-hour milk intake by infant age and weight, and state normal stool and urine output benchmarks for days 1–5 and beyond

  • Outline a responsive feeding plan that names early hunger cues, satiety cues, and the recommended feeding frequency in the first weeks

  • Explain the physiology behind supply-and-demand regulation, including the role of milk removal frequency and glandular emptying

  • Construct a prenatal breastfeeding education outline covering colostrum, skin-to-skin, rooming-in, and avoidance of unnecessary supplementation

Your checkpoint

A two-page written latch-and-position teaching protocol plus a cue-based feeding handout suitable to give to a parent, reviewed for accuracy line by line

Week 3

Normal Breastfeeding and Lactation Management & Assessment and Care of the Breastfeeding Dyad

  • Perform a structured dyad assessment - maternal history, breast and nipple exam, infant oral exam, and observed feed - and write up findings in SOAP format

  • Classify nipple and breast variants (flat, inverted, retracted, sore, cracked, blanched) and match each to a first-line management step

  • Evaluate infant weight trajectories using WHO growth standards, distinguishing normal newborn weight loss from excessive loss requiring action

  • Score and interpret a feeding observation using a validated tool's domains (latch depth, suck pattern, audible swallowing, milk transfer signs)

  • Draft a differential for poor milk transfer that separates maternal, infant, and dyadic causes

Your checkpoint

Three complete SOAP notes on simulated dyad cases (one normal, one nipple-trauma case, one poor-weight-gain case) with a defensible assessment and plan for each

Week 4

Assessment and Care of the Breastfeeding Dyad & Complex Breastfeeding and Lactation Problems

  • Diagnose and stage engorgement, plugged ducts, and mastitis, and write evidence-based management for each including when to continue feeding

  • Differentiate inflammatory mastitis from bacterial infection and from abscess, naming the findings that change management

  • Explain the pathophysiology and management of nipple candidiasis and of vasospasm/Raynaud phenomenon, distinguishing them clinically

  • Assess low milk supply with a structured approach that rules out insufficient removal, endocrine causes, and anatomic causes before concluding glandular insufficiency

  • Describe the recognition and immediate referral pathway for neonatal dehydration and hypernatremia in the breastfeeding newborn

Your checkpoint

A comparison table of six breast and nipple conditions with columns for clinical signs, pathophysiology, first-line management, escalation trigger, and whether breastfeeding continues

Week 5

Complex Breastfeeding and Lactation Problems

  • Evaluate ankyloglossia using a structured functional assessment and justify whether release is indicated based on feeding function rather than appearance alone

  • Explain the mechanism and management of hyperlactation and oversupply, including foremilk/hindmilk misconceptions

  • Plan care for the late-preterm or small-for-gestational-age infant, covering supplementation decisions, paced bottle feeding, and triple feeding logistics

  • Describe the management of breastfeeding during maternal surgery, hospitalization, and separation, including pumping schedules to preserve supply

  • Outline the support plan for a parent returning to work, naming pump schedule, storage limits, and workplace accommodation talking points

Your checkpoint

Two case analyses of 600+ words each - one infant with oral restriction and one maternal supply problem - with differential, decision rationale, and a 2-week follow-up plan

Week 6

Pharmacology and Toxicology in Lactation & Nutrition, Growth, and Development in Breastfed Infants

  • Apply the principles of relative infant dose and milk-to-plasma ratio to judge whether a maternal medication is compatible with breastfeeding

  • Classify 20 commonly encountered drug classes (analgesics, antidepressants, antihypertensives, antiepileptics, galactagogues, contraceptives) as compatible, monitor, or avoid, with the reasoning stated

  • Describe the handling of radiologic contrast, anesthesia, and alcohol or cannabis exposure during lactation

  • Interpret WHO growth charts and distinguish faltering growth from constitutional small size using serial measurements and velocity

  • Explain the energy, protein, iron, zinc, and vitamin D requirements of the exclusively and partially breastfed infant, including the rationale for vitamin D supplementation

Your checkpoint

A 20-row drug reference card with drug class, lactation risk category, cited reasoning, and monitoring note, plus a one-page growth-chart interpretation exercise

Week 7

Professional Practice, Ethics, and Research & Complex Breastfeeding and Lactation Problems

  • Apply the IBCLC scope of practice and code of ethics to five written scenarios involving scope limits, referral duty, and conflict of interest

  • Critique a published lactation study by identifying design, bias risk, confounders, and whether the conclusion is supported

  • Summarize the key provisions of the WHO Code and subsequent resolutions relevant to a clinician's own practice and to accepting gifts or samples

  • Explain informed consent, documentation standards, and confidentiality obligations in lactation consultations

  • Rehearse culturally sensitive counseling for a parent who declines a recommended intervention

Your checkpoint

A structured critical appraisal of one primary lactation research article (400+ words) plus a written ethics response to two of the scenarios

Week 8

Maternal and Infant Anatomy and Physiology & Normal Breastfeeding and Lactation Management & Assessment and Care of the Breastfeeding Dyad & Complex Breastfeeding and Lactation Problems & Pharmacology and Toxicology in Lactation & Nutrition, Growth, and Development in Breastfed Infants & Professional Practice, Ethics, and Research

  • Complete two full-length timed practice exams and log every missed item by domain

  • Re-teach your three weakest topics from source material and rewrite the notes in your own words

  • Drill 60 rapid-fire recall items on anatomy, hormones, drug compatibility, and growth standards until each is answered without hesitation

  • Re-read your own week 1–7 deliverables and correct any error you now recognize

  • Build a one-page pre-exam summary sheet of numbers, thresholds, and referral triggers

Your checkpoint

A scored practice-exam log with a per-domain accuracy percentage, a ranked list of remaining weak areas, and the completed one-page summary sheet

Milestones

Week 2: Explain lactogenesis, the milk ejection reflex, and a correct latch from memory in under 5 minutes without notes; if any gap appears, redo week 1 goals before moving on

Week 4: Produce a complete SOAP note on an unseen dyad case in 25 minutes and correctly identify the primary problem in at least 3 of 4 practice cases

Week 6: Score at least 80% on a self-made 30-item quiz covering drug compatibility and infant nutrition, and interpret two growth charts correctly

Week 8: Score at least 75% on both timed practice exams with no domain below 65%; schedule the exam only after this threshold is met
