IBCLC common mistakes
IBCLC · Understand the traps and how to avoid them.
Selects the option that matches what is routinely done in their own unit or clinic, even when the stem describes an infant or setting where that routine is not the safest course.
Years of local custom create a strong 'this is how we do it here' pull, and habitual practice feels more trustworthy under exam pressure than a guideline the candidate half-remembers.
What to do instead
Before committing, ask: 'Is this the safest option supported by current guidance for this particular mother-infant pair?' Treat institutional habit as a distractor unless the stem explicitly limits resources so that only that option is feasible.
Chooses an option that is factually true but does not answer the question asked, because the stem's qualifier (first, next, most likely, except, contraindicated, initial) was skimmed.
Under time pressure candidates pattern-match the stem to a memorised fact and then read each option only far enough to confirm that fact, not to check what the stem actually requested.
What to do instead
Read the final line of the stem first, restate the task in your own words, then read the options and physically eliminate any option that answers a different question, however correct it is on its own.
Reasons about a newborn using adult or older-child parameters: expecting a 3-day-old to take 60-90 mL per feed, expecting a neonate to concentrate urine, expecting adult-type sleep consolidation, or expecting a young infant to mount a fever readily.
Adult physiology is over-learned and the day-by-day developmental timeline for gastric capacity, renal concentrating ability, thermoregulation and feeding frequency blurs easily when facts are recalled in isolation.
What to do instead
Memorise anchor numbers and attach each to a day of life: colostrum intake roughly 2-10 mL per feed in the first 24 hours, gastric capacity about 5-7 mL on day 1 rising to about 45-60 mL by day 7, 8-12 feeds per 24 hours, term newborns handle a fluid load poorly and concentrate urine poorly.
Concludes 'low milk supply' from a crying baby, short or frequent feeds, or a single weight measurement, without first establishing latch and oral anatomy, suck-swallow-breathe coordination, 24-hour nappy and stool output, and pre/post feed weights on the same scale.
Crying and perceived short feeds are the commonest presenting complaints in practice and feel diagnostic; exam stems deliberately withhold the confirming data to test whether the candidate asks for it rather than assuming.
What to do instead
Choose the option that gathers the missing data or treats the identified cause. Reserve 'insufficient milk' for cases where intake, output and transfer data support it; remember perceived insufficient milk is far more common than true insufficiency, and that a weighted feed requires the same scale, same clothing state, and no intervening nappy change or feed.
Marks a drug as incompatible with breastfeeding because it appears on a caution or 'avoid' list, without weighing route of administration, protein binding, oral bioavailability, half-life, and relative infant dose.
Candidates memorise drug-name lists rather than the pharmacokinetic reasoning that generated them, so any warning label reads as an absolute prohibition.
What to do instead
For every drug, run the same three questions: how much reaches milk, how much survives the infant gut, and how large is that exposure relative to a therapeutic infant dose. A relative infant dose under about 10 percent is generally reassuring. Know the common compatibles (ibuprofen, paracetamol, most penicillins and cephalosporins, sertraline) against the genuine cautions (codeine and tramadol, cytotoxic agents, radioisotopes).
Reassures and continues conservative management when the stem contains one red flag embedded among reassuring findings: fever with a tender red breast, a new fixed mass, a baby with few wet nappies plus a sunken fontanelle, or unilateral pain that has not improved after 24-48 hours of correct management.
Most breastfeeding problems do resolve with support, so the reflex is to normalise; candidates under-weight a single ominous finding when the rest of the stem sounds like a familiar, manageable picture.
What to do instead
Scan each stem specifically for the finding that must not be missed, and let it override the overall pattern. Keep short memorised referral lists: mastitis with systemic illness or no improvement, suspected abscess, any fixed mass suggesting inflammatory breast cancer, infant dehydration or jaundice, and weight loss beyond about 10 percent with poor output.
Answers with a technical intervention (pump more, try a nipple shield, add a supplement) when the stem centres on a mother who is exhausted, in pain, tearful, or openly ambivalent about continuing to breastfeed.
Candidates study techniques intensively and have far more practice solving latch and supply problems than reading psychosocial cues, so emotional content in the stem is treated as background colour rather than the problem to be solved.
What to do instead
When a stem names a feeling, a relationship, or a decision, choose the option that first validates the mother's experience, screens for perinatal mood disorder (for example with the EPDS), and supports shared decision-making; a technical step, if offered, should come alongside that rather than instead of it.
Endorses or overlooks practices that breach the International Code of Marketing of Breast-milk Substitutes - accepting or handing out company samples, displaying manufacturer materials in a clinic, or recommending a specific brand - or imposes the clinician's own cultural feeding norm on a family with different traditions.
These behaviours are routine in many facilities and therefore feel benign, and Code content tends to be studied as background ethics rather than as testable, concrete rules.
What to do instead
Learn the Code as a set of specific prohibitions on marketing to health workers and to the public, and be able to name what is and is not permitted. When a stem involves culture or family custom, choose the option that asks about the family's practices and negotiates a plan within them, not the option that corrects them.
Labels normal infant behaviour as a feeding problem: evening cluster feeding, 8-12 or more feeds in 24 hours, brief comfort sucking, night waking at four months, or a shift in centile that stays within normal channels.
Parents bring these as complaints, and candidates absorb the parental framing; growth-chart confusion between WHO and CDC references compounds the error.
What to do instead
Recite the normal ranges before evaluating: stool transition from meconium to green to yellow by day 4-5, at least six wet nappies a day by day 5, weight nadir within 7-10 percent and regained by day 10-14, wide variation in night waking across the first two years. Use WHO standards for 0-2 years and interpret a centile shift against the whole growth trajectory, not one plot.
Mismanages the regulation of milk production: adding frequent pumping and longer feeds for an oversupply, or assuming prolactin alone determines output with no role for milk retained in the breast.
The endocrine and autocrine details are memorised as isolated facts and never linked to the clinical decisions they actually drive, so management is chosen by habit rather than mechanism.
What to do instead
Anchor each management choice to its mechanism: effective removal in the first two weeks upregulates prolactin receptors and sets long-term capacity; milk left in the breast raises the feedback inhibitor of lactation and downregulates output locally. For oversupply, reduce the removal stimulus (block or single-side feeding, avoid unnecessary pumping) rather than increasing it.
