Two Credentials, One Goal

When you are struggling with breastfeeding and someone tells you to "see a lactation consultant," it can feel straightforward enough. But search for one, and you quickly discover a confusing alphabet soup of credentials: CLC, IBCLC, CLE, CLEC, CBS. They all seem to involve lactation, but what do the letters actually mean? And more importantly, which one do you need?

The two most common credentials you will encounter are CLC (Certified Lactation Counselor) and IBCLC (International Board Certified Lactation Consultant). Both are legitimate professionals who can help with breastfeeding, but they represent different levels of training, different scopes of practice, and different price points. Understanding the distinction can help you find the right support for your specific situation.

What Is a CLC?

A Certified Lactation Counselor (CLC) is a professional who has completed an accredited lactation education program and passed a certification exam administered by the Academy of Lactation Policy and Practice (ALPP). The CLC credential requires:

  • A minimum of 45 hours of lactation-specific education, typically delivered as an intensive course over five to seven days
  • A written certification exam covering lactation physiology, common breastfeeding challenges, counseling techniques, and cultural competence
  • Continuing education to maintain certification (additional hours every five years)

CLCs are trained to support normal breastfeeding and to identify when a situation requires referral to a higher level of care. Many CLCs work in hospitals, WIC offices, community health centers, pediatric offices, and private practice.

What Is an IBCLC?

An International Board Certified Lactation Consultant (IBCLC) holds the highest internationally recognized credential in lactation care. The IBCLC certification, administered by the International Board of Lactation Consultant Examiners (IBLCE), requires:

  • Extensive prerequisite education in health sciences, including anatomy, physiology, nutrition, psychology, and child development (14 health science courses)
  • A minimum of 90 hours of lactation-specific education from an accredited program
  • Supervised clinical hours working directly with breastfeeding families (300 to 1,000 hours depending on the pathway)
  • A rigorous certification exam that covers pathology, pharmacology, medical conditions affecting lactation, and complex clinical scenarios
  • Recertification every five years through continuing education or re-examination

IBCLCs are the clinical specialists of the lactation world. They are trained to assess and manage complex breastfeeding problems, including those involving infant oral anatomy (like tongue ties), maternal medical conditions, premature infants, and situations requiring coordination with other healthcare providers.

Side-by-Side Comparison

Training Depth

The most significant difference is the depth and breadth of training. A CLC completes approximately 45 hours of lactation education. An IBCLC completes at least 90 hours of lactation education plus hundreds of supervised clinical hours and extensive prerequisite coursework in health sciences. This means an IBCLC has substantially more training in the medical and pathological aspects of lactation.

Scope of Practice

  • CLCs are trained to support normal, uncomplicated breastfeeding. They can help with latching, positioning, milk supply basics, pumping guidance, and common early challenges. They are also trained to recognize when a problem exceeds their scope and to refer to an IBCLC or other healthcare provider.
  • IBCLCs can do everything a CLC does, plus assess and create care plans for complex situations. This includes evaluating for tongue and lip ties, managing low milk supply with a comprehensive workup, supporting breastfeeding with medical conditions (diabetes, thyroid disorders, breast surgery history), working with premature or NICU babies, and coordinating with physicians on medication compatibility.

Where They Work

  • CLCs are commonly found in WIC offices, community health settings, hospital postpartum units, and pediatric practices. They often serve as the first point of contact for breastfeeding support.
  • IBCLCs work in hospitals (often in NICU and postpartum units), private practice, pediatric and OB/GYN offices, and community settings. They are more likely to be the specialist you are referred to when initial support has not resolved the issue.

Cost

  • CLC visits are generally less expensive, often ranging from $50 to $150 per session. Many WIC offices provide CLC services at no cost. Some community health programs also offer free CLC support.
  • IBCLC visits typically range from $150 to $350 per session, with initial consultations sometimes costing more than follow-ups. Insurance coverage for IBCLC visits has been expanding. Under the Affordable Care Act, many insurance plans are required to cover breastfeeding support and counseling, which may include IBCLC visits.

Insurance Coverage

Insurance coverage varies by state and plan. The ACA mandates coverage of breastfeeding support, but what qualifies as "covered" differs. Some plans cover only IBCLC visits, others cover both CLC and IBCLC, and some require a physician referral. Always call your insurance provider and ask specifically about lactation support coverage, including the credential types they will reimburse.

When to See a CLC

A CLC is an excellent choice when:

  • You want proactive support in the first days of breastfeeding, before problems develop
  • You are having common early challenges with latch, positioning, or sore nipples
  • You need pumping guidance (when to start, how often, flange sizing basics)
  • You are returning to work and need help planning a pumping schedule
  • You want reassurance that breastfeeding is going well
  • You need support with bottle introduction or weaning
  • Cost is a primary concern and your situation is straightforward

CLCs are often more accessible and affordable, making them a great first step for many families. If your CLC identifies a concern beyond their scope, they will refer you to an IBCLC.

When to See an IBCLC

An IBCLC is the better choice when:

  • Your baby is not gaining weight adequately
  • You suspect a tongue tie, lip tie, or other oral anatomy concern
  • You have persistent pain during breastfeeding that has not improved with basic latch correction
  • You have a history of breast surgery (reduction, augmentation, or biopsy)
  • You are managing a medical condition that may affect milk supply (thyroid disorders, PCOS, diabetes, insufficient glandular tissue)
  • Your baby was born premature or has spent time in the NICU
  • You are relactating (restarting milk production after stopping) or inducing lactation (producing milk without a pregnancy)
  • You are taking medications and need guidance on compatibility with breastfeeding
  • You have seen a CLC and the issue has not resolved
  • You are experiencing recurrent mastitis or other breast infections

Can You See Both?

Absolutely. In fact, many families benefit from seeing both a CLC and an IBCLC at different points in their breastfeeding journey. A CLC might provide the initial support in the hospital and the first week home, while an IBCLC steps in for a specific clinical issue that arises later.

Some practices employ both CLCs and IBCLCs, allowing them to triage effectively. You might start with a CLC appointment for a general assessment, and if the CLC identifies something that needs a deeper clinical evaluation, they can bring in the IBCLC.

Other Lactation Credentials You Might Encounter

  • CLE (Certified Lactation Educator): Focused on teaching and education rather than clinical support. Often leads group classes or provides basic one-on-one guidance.
  • CBS (Certified Breastfeeding Specialist): Similar scope to a CLC. The credential is offered through a different certifying body.
  • La Leche League Leaders: Trained peer supporters who facilitate support groups and offer mother-to-mother guidance. Not a clinical credential, but a valuable source of community support.

How to Choose

Start by honestly assessing your situation:

  • If things are generally going well and you want a tune-up or some confidence-building, a CLC is a great, cost-effective choice.
  • If something specific is wrong and you need a clinical assessment, go straight to an IBCLC.
  • If you are not sure, start with a CLC. A good CLC will tell you if you need an IBCLC, and you will not have lost anything by starting there.

No matter which credential you choose, look for someone who listens to your goals, respects your choices (including the choice to supplement or stop breastfeeding), and makes you feel supported rather than judged.

You can find both CLCs and IBCLCs in your area on BAABY. Every provider listing includes their credentials so you can choose the level of support that fits your needs.
