What is an IBCLC? Feeding Support Explained
Updated: 1 day ago
IBCLC stands for International Board Certified Lactation Consultant. It is an internationally recognised, board-certified professional credential for practitioners specialising in lactation and infant feeding.
Becoming an IBCLC requires a defined combination of health-science education, lactation-specific education, substantial clinical experience and successful completion of the IBCLC examination. The credential is maintained through ongoing recertification requirements.
An IBCLC can support a feeding dyad from before birth, through the establishment and development of feeding, and for as long as the dyad chooses to seek support. Their expertise encompasses far more than breastfeeding alone and can include breastfeeding or chestfeeding, expressing, bottle feeding, infant formula feeding, combination feeding, relactation, changing feeding methods and weaning.
Importantly, IBCLC is a professional credential rather than a primary healthcare profession. IBCLCs come from a range of professional backgrounds, and their scope of practice is determined by their IBCLC scope alongside any other professional registration, qualifications, legislation and local requirements.
Understanding what the IBCLC credential represents can help families distinguish between the different types of breastfeeding and infant-feeding support available and choose support appropriate to their needs.
What does it take to become an IBCLC?
The IBCLC credential is not awarded simply because someone has experience breastfeeding their own children or has attended a short breastfeeding course.
There are defined eligibility requirements. Candidates must complete health-sciences education, lactation-specific education and substantial lactation-specific clinical experience before they can sit the examination.
The current certification requirements include 95 hours of lactation-specific education, comprising 90 hours of lactation education, including education relating to the WHO Code, together with communication education. Candidates must also meet the clinical-experience requirements of one of the recognised pathways to certification.
There are three routes to gaining the required clinical experience:
Pathway 1: at least 1,000 hours of lactation-specific clinical practice in an appropriate supervised setting within the required timeframe.
Pathway 2: completion of an accredited lactation academic programme, including at least 300 hours of directly supervised lactation-specific clinical practice.
Pathway 3: completion of a verified, pre-approved mentorship route, including at least 500 hours of directly supervised lactation-specific clinical practice.
Clinical hours must involve providing lactation care; simply observing or shadowing another practitioner does not meet the requirement. Personal breastfeeding experience, or supporting family and friends informally, also does not count as clinical practice.
Candidates must then successfully complete the IBCLC examination before being awarded the credential.
This means that an IBCLC has undertaken a substantial and structured programme of education, clinical experience and examination specifically related to lactation and infant feeding.
Who are IBCLCs?
IBCLCs come from different professional and educational backgrounds. Some are nurses, midwives, doctors, dietitians, speech and language therapists or other healthcare professionals. Others enter the profession through recognised lactation-specific routes.
What they have in common is the additional education, clinical experience and examination required for the IBCLC credential.
An IBCLC may therefore have another professional registration alongside their IBCLC credential. This is important because their additional professional registration may give them a separate scope of practice that is different from their IBCLC scope.
For example, an IBCLC who is also a registered nurse may have nursing responsibilities and competencies that another IBCLC does not. Similarly, an IBCLC who is also a doctor, midwife or another regulated professional will have the scope of that profession alongside their lactation expertise.
The IBCLC credential itself, however, relates specifically to specialist lactation and infant-feeding knowledge and clinical practice.
“Lactation consultant” does not necessarily mean IBCLC
Families should also be aware that the term lactation consultant is not, in itself, a legally protected professional title in the UK.
This means that someone describing themselves as a lactation consultant is not necessarily an IBCLC.
There are many knowledgeable and experienced people providing valuable breastfeeding and infant-feeding support who hold different qualifications. These may include breastfeeding counsellors, peer supporters and practitioners with other lactation or feeding qualifications.
The important distinction is that IBCLC identifies a specific internationally recognised, board-certified credential with defined eligibility, examination and recertification requirements.
For families, it is therefore reasonable to ask what qualification a person holds, what their clinical background is, and what experience they have with the particular feeding issue they are seeking help with.
What can an IBCLC help with?
IBCLC care is not limited to breastfeeding.
An IBCLC can support families with a wide range of infant-feeding situations, including:
preparing for breastfeeding before birth
getting feeding established after birth
positioning and attachment
painful feeding and nipple pain
concerns about milk transfer
milk supply concerns
expressing and breast-pump use
flange fitting and pumping technique
responsive bottle feeding
feeding expressed breast milk
infant formula feeding
combination feeding
transitioning between breast, bottle and other feeding methods
relactation
feeding after a period of separation
changing or reducing breastfeeding
weaning and ending breastfeeding
This means that seeing an IBCLC does not mean that a family has to be exclusively breastfeeding, or that the aim of support is necessarily to increase breastfeeding.
The role of the IBCLC is to provide specialist assessment, information and support around lactation and infant feeding while working with the family's individual circumstances, choices and goals.
IBCLC care and medical care
An IBCLC is a specialist in lactation and infant feeding. They are not a replacement for a GP, paediatrician or other medical professional.
However, this distinction does not mean that an IBCLC should only deal with simple feeding problems.
IBCLCs are trained to take a detailed history and undertake comprehensive maternal, infant and feeding assessments within their scope of practice. Through this assessment they may identify signs, symptoms or patterns that warrant further medical assessment.
For example, an IBCLC may recognise that a persistent milk-supply concern could warrant investigation of factors such as insufficient glandular tissue, hormonal or endocrine factors, medication effects or other underlying issues. They may recognise symptoms consistent with mastitis or another condition requiring medical assessment.
The IBCLC can explain their findings to the family and recommend that they discuss the concern with an appropriate healthcare professional.
However, a recommendation from an IBCLC does not oblige a GP or another healthcare professional to undertake a particular investigation or treatment. A GP remains responsible for making their own clinical assessment and decisions within the scope, standards and regulatory requirements of their own profession.
This is an important part of multidisciplinary care. The IBCLC contributes specialist lactation and infant-feeding expertise; the GP or other medical professional contributes their own medical expertise and clinical responsibility.
The two roles should complement one another rather than one professional being expected to undertake the role of the other.
What about tongue-tie?
Tongue-tie is a good example of why specialist infant-feeding assessment can be valuable.
An IBCLC does not have authority to diagnose tongue-tie simply because they hold the IBCLC credential. The IBCLC scope allows comprehensive maternal, infant and feeding assessment related to lactation, but diagnosis of a disease or medical condition is outside the IBCLC scope unless the practitioner has separate professional authority to do so.
An IBCLC can, however, assess feeding function, observe how an infant is using their mouth and tongue during feeding, document relevant findings and identify when further assessment may be appropriate.
This is particularly important with tongue-tie because the presence of a frenulum is an anatomical finding; it does not, by itself, establish that feeding is impaired or explain the whole clinical picture.
Anatomy provides information. Function provides context.
Tongue-tie-related feeding concerns can be multifactorial, involving oral function, feeding mechanics, infant regulation, maternal factors, positioning, milk transfer and other aspects of the feeding relationship.
This is one reason specialist lactation knowledge can be particularly valuable when assessing a feeding concern in which tongue-tie may be part of the picture. It also demonstrates why a multidisciplinary approach can be more appropriate than expecting one professional to assess every aspect of an infant's health and development.
An IBCLC may therefore identify a concern, undertake the aspects of assessment that fall within their scope, explain what they have observed and refer or recommend further assessment where appropriate.
The IBCLC credential itself does not authorise frenulotomy. Where an IBCLC also performs tongue-tie division, that must arise from separate professional registration, training and legal authority applicable to the practitioner and jurisdiction.
Why multidisciplinary care matters
Good infant-feeding care does not depend on one professional having all the answers.
An IBCLC may work alongside a GP, paediatrician, midwife, health visitor, speech and language therapist, dietitian, pharmacist, physiotherapist, occupational therapist, dentist or another appropriately qualified professional, depending on the needs of the infant and family.
Each professional brings a different area of expertise.
The IBCLC contributes specialist knowledge of lactation and infant feeding. A medical professional contributes medical assessment and management. A speech and language therapist may contribute expertise in communication and swallowing. A dietitian may contribute nutritional assessment. Other professionals may assess musculoskeletal, developmental, oral-health or other factors.
The purpose is not to pass responsibility from one professional to another. It is to bring together the appropriate expertise while keeping the infant and feeding dyad at the centre of care.
How do you choose an IBCLC?
If you are considering an IBCLC, it is reasonable to look beyond the letters after someone's name.
First, check that their IBCLC credential is current. Current IBCLCs can be verified through the international IBCLC professional register.
In the UK, the Lactation Consultants of Great Britain (LCGB) also provides a directory of IBCLCs who are current LCGB members. LCGB is the professional association for IBCLCs in Great Britain and provides education and professional support for its members.
It can also be helpful to consider:
the practitioner's professional background and additional qualifications
their experience with the type of feeding issue you are experiencing
whether they regularly work with infants of your baby's age and needs
whether they offer the type of feeding support you are looking for
recommendations from other families
independent reviews and feedback about their service
whether they work collaboratively with other healthcare professionals when this is appropriate
Reviews and recommendations can provide useful insight into a practitioner's communication, accessibility and families' experiences, but they should not replace checking the person's actual professional credentials and experience.
LCGB's “Who's Who in Breastfeeding Support and Lactation in the UK” is also a useful resource for understanding the differences between IBCLCs, breastfeeding counsellors, peer supporters and other forms of breastfeeding support.
The important thing to remember
An IBCLC is a specialist in lactation and infant feeding who has met defined education, clinical-experience and examination requirements to obtain an internationally recognised board-certified credential.
Their expertise can extend from before birth through the entire feeding journey — whether that journey involves breastfeeding, chestfeeding, expressing, bottle feeding, formula feeding, combination feeding, relactation, changing feeding methods or weaning.
They do not replace other healthcare professionals, nor should they be expected to. Instead, an IBCLC can provide specialist assessment and support within their scope while working alongside other professionals when additional expertise is needed.
For families, understanding what the IBCLC credential actually represents makes it easier to distinguish between different types of feeding support and to choose a practitioner whose qualifications, experience and approach are appropriate for their individual needs.
