Where Lactation Expertise Leads the Way
International Board Certified Lactation Consultants are often the first professionals to suspect a tongue-tie, and for good reason. You watch feeds. You see the latch, the transfer, the maternal pain, the patterns a brief clinical visit misses. Your functional assessment is frequently the most important input in the entire tongue-tie evaluation process.
This guide is a practical framework for functional tongue-tie assessment from a lactation perspective. It covers what to observe, how to assess tongue function, how to distinguish restriction from other causes, and how to document your findings for an effective referral.
At Latched Beginnings in Austin, Dr. Kacie Culotta deeply values IBCLC assessments and built her referral process around collaboration with lactation professionals. Here's a shared framework.
Start With the Feeding History
A thorough functional assessment begins before you look in the baby's mouth. The history frames everything. Gather the maternal experience of pain, nipple trauma, and supply, the baby's weight gain trajectory and diaper output, the timing and pattern of feeds, and what supports have already been tried.
This context separates a baby who may have a restriction from one whose issues stem from positioning, oversupply, or other causes. The history also gives the evaluating provider the clinical picture they need, so capture it carefully.
Observe the Feed
Direct observation of a feed is the heart of functional assessment. Watch for these elements.
Latch Quality and Depth
Assess whether the baby achieves a deep, asymmetric latch or stays shallow, with lips that don't flange and a latch that slips.
Milk Transfer
Look for rhythmic suck-swallow patterns and audible swallowing versus fluttering, frequent pausing, and signs of poor transfer. A pre- and post-feed weight can quantify this.
Compensations and Fatigue
Note clicking, loss of suction, jaw or cheek compensations, milk leaking, and a baby who tires quickly or falls asleep from effort.
Maternal Comfort
Observe pain during the feed and the shape of the nipple afterward. A compressed, blanched, or lipstick-shaped nipple suggests compression from poor mechanics.
Assess Tongue Function Directly
Beyond the feed, a hands-on functional assessment of the tongue adds critical information. Within your scope, assess tongue elevation, extension, lateralization, and cupping, and the quality of the suck on a clean finger. Note whether the tongue can lift toward the palate, whether it can extend over the lower gum, and how it responds during a suck.
Functional assessment frameworks like the Hazelbaker Assessment Tool for Lingual Frenulum Function can structure this part. The goal is to characterize how the tongue moves and functions, not simply whether a frenulum is visible. Posterior restrictions in particular are identified through function rather than obvious appearance.
Distinguish Restriction From Other Causes
A skilled functional assessment also rules things out. Feeding difficulties can stem from oversupply or forceful letdown, positioning issues, birth-related tension, prematurity or sleepiness, or maternal anatomy, none of which a tongue-tie release would address.
Trialing positioning changes, addressing letdown, and considering bodywork before or alongside referral helps clarify whether a restriction is truly the driver. This differential thinking is what makes an IBCLC assessment so valuable to the evaluating provider, and what protects families from unnecessary procedures.
Document and Refer Effectively
When your assessment supports referral, clear documentation makes the handoff productive. Summarize the maternal history and symptoms, the weight and diaper data, your feed observations, your tongue function findings, and the supports already trialed. State your clinical impression and the reason for referral.
This documentation lets the evaluating provider build on your work rather than starting from scratch, and it keeps the family from repeating the whole story. It also creates a shared record that supports collaborative follow-up after any treatment.
Collaborating With Latched Beginnings in Austin
Latched Beginnings is structured around exactly this kind of collaboration. Dr. Kacie Culotta, DDS holds both a laser certification for tongue-tie releases and a lactation counselor certification, so she speaks the same functional language IBCLCs use. She treats your assessment as a central input, not an afterthought.
She shares a conservative, function-first philosophy, communicates back about shared patients, and coordinates post-release lactation support so families have continuity of care. Many IBCLCs across the Austin area refer to Latched Beginnings precisely because the collaboration is genuine and two-way.
If you're an IBCLC looking for an aligned referral partner for infant oral ties, we'd love to build that relationship. We can share referral forms and discuss how we coordinate care around your assessments.
Frequently Asked Questions
What is a functional tongue-tie assessment?
A functional tongue-tie assessment evaluates how the tongue moves and works during feeding, rather than just whether a frenulum is visible. It includes feeding history, direct feed observation, and hands-on assessment of tongue elevation, extension, lateralization, and cupping. Function-first assessment identifies restrictions, including posterior ties, that appearance alone would miss.
What should an IBCLC observe during a feed for tongue-tie?
Observe latch quality and depth, milk transfer through suck-swallow patterns and audible swallowing, compensations like clicking and loss of suction, fatigue, and maternal comfort including nipple shape after the feed. A pre- and post-feed weight can quantify transfer. These observations are central to a functional assessment.
How do I assess tongue function in an infant?
Within your scope, assess tongue elevation toward the palate, extension over the lower gum, lateralization, cupping, and the quality of the suck on a clean finger. Structured tools like the Hazelbaker Assessment Tool can guide this. The goal is to characterize how the tongue functions, since posterior restrictions are identified through function, not obvious appearance.
How do I tell a tongue-tie from other feeding problems?
Differentiate by ruling out oversupply or forceful letdown, positioning issues, birth-related tension, prematurity or sleepiness, and maternal anatomy. Trialing positioning changes, addressing letdown, and considering bodywork helps clarify whether a restriction is truly driving the difficulty. This differential thinking protects families from unnecessary procedures.
What should I document when referring for a tongue-tie evaluation?
Document the maternal history and symptoms, weight and diaper data, feed observations, tongue function findings, the supports already trialed, your clinical impression, and the reason for referral. Clear documentation lets the evaluating provider build on your work and spares the family from repeating their story.
Does an IBCLC diagnose tongue-tie?
IBCLCs perform functional assessments and identify when a restriction is likely affecting feeding, then refer to a provider who can diagnose and treat. The IBCLC's functional assessment is often the most valuable input in the process, and collaborative providers treat it as central to the evaluation rather than an afterthought.
Why does collaboration between IBCLCs and the releasing provider matter?
Collaboration ensures the functional assessment informs the evaluation, that families receive consistent guidance, and that post-release lactation support provides continuity of care. Two-way communication about shared patients improves outcomes and keeps everyone aligned around the baby's actual needs rather than working in silos.
