Does Your Baby Have Tongue Tie? Signs and Symptoms to Know
Maybe nursing hurts more than you expected. Maybe your baby is fussy after feeds. Maybe your baby clicks while feeding, or a friend mentioned that their baby had a tongue tie. However you got here, you're probably wondering: could my baby have one?
This article walks through the signs parents most often notice, what else can cause these symptoms, and what to do next. One important note first: only a physician or dentist can diagnose tongue tie. The signs below are reasons to get your baby checked, not a way to diagnose at home.
What is tongue tie?
Every baby has a lingual frenulum, a thin band of tissue connecting the underside of the tongue to the floor of the mouth. In tongue tie (ankyloglossia), this tissue is short, tight, or attached in a way that may limit how the tongue moves.
Frenula vary a lot from baby to baby. A frenulum that looks tight doesn't always cause problems. What matters most is whether it affects how your baby feeds.

Signs you might see in your baby's mouth
Some parents notice differences in how their baby's tongue looks or moves:
A heart-shaped or notched tongue tip when the tongue is lifted or pushed forward
Difficulty lifting the tongue toward the roof of the mouth when crying
The tongue not reaching past the lower gum when your baby tries to stick it out
A visible band of tissue close to the tip of the tongue
Some babies with tongue tie don't show any visible signs, and some babies with visible differences feed just fine. That's why feeding signs and a comprehensive oral functional assessment are often more meaningful than appearance.
Signs during breastfeeding
Tongue tie is most often noticed during nursing, because breastfeeding asks a lot of the tongue. Signs can include:
Trouble latching, or a latch that feels shallow
Slipping off the breast often
Clicking or smacking sounds while feeding
Very long feeds, or wanting to feed constantly
Falling asleep quickly at the breast or seeming frustrated
Gassiness or spitting up from swallowing air
Slow weight gain

Signs the nursing parent may notice
Sometimes the first clues come from the person nursing:
Nipple pain that continues throughout feeds
Nipples that look flattened, creased, or lipstick-shaped after feeding
Cracked, bleeding, or damaged nipples
Breasts that don't feel softer after feeds
Concerns about milk supply
Baby is fussy at the breast
Some tenderness in the first days can be common. Ongoing pain is a reason to get support, not something you have to push through.
Signs during bottle-feeding
Many babies with tongue tie bottle feed well, but some show signs like:
Milk leaking from the corners of the mouth
Clicking during feeds
Gulping, coughing, or sputtering
Tiring quickly or taking a long time to finish
Fussy and gassy after feeds

Important: these signs have many possible causes
Here's what many online checklists leave out. Almost every sign on this page can be caused by something other than tongue tie. Other common reasons for feeding difficulty include:
Positioning or how your baby's body is supported
Body tension or a baby who seems stiff or uncomfortable
A sleepy newborn, prematurity, or a difficult birth
Nasal congestion
Reflux
Breast or nipple factors, such as engorgement or nipple shape
Fast or slow milk flow
Head turn preference or torticollis
This is why a careful, team-based approach matters. If a feeding problem is caused by something else, treating tongue tie won't solve it.
When to call your pediatrician right away
Contact your pediatrician promptly if your baby:
Isn't gaining weight as expected
Has fewer wet or dirty diapers than usual
Is very sleepy or hard to wake for feeds
Coughs or chokes often while feeding
Has trouble breathing during feeds
What to do if you notice these signs
Start with your pediatrician and a lactation consultant. Your pediatrician can check your baby's growth and health. A lactation consultant (IBCLC) can assess latch and milk transfer and help you adjust positioning.
Ask about a tongue tie evaluation if concerns continue. A physician or dentist, such as your pediatrician, an ENT, or a pediatric dentist, can evaluate your baby and decide whether tongue tie is present and whether a release is appropriate.
Consider feeding support and a functional oral assessment. An occupational therapist who works with infants can look at how your baby uses their mouth and body during feeding, including oral-motor skills, posture, body tension, and suck-swallow-breathe coordination. An OT doesn't diagnose tongue tie, but works alongside your lactation consultant and can share observations with your baby's care team. Learn more in [What Happens at an Infant Feeding OT Visit].
Trust what you're noticing
You know your baby best. If feeding feels hard, painful, or stressful, it's worth asking for help, whether the cause turns out to be tongue tie or something else entirely.
