Hearing clicking while your baby nurses can leave you wondering whether their latch is working, whether they’re swallowing air, or whether they might have a tongue tie. You may have been told everything looks fine, but you’re still hearing something that makes you pause.

Clicking usually means your baby is briefly losing suction during the feed. It gives you information about what’s happening, but the sound alone doesn’t tell you why—or whether feeding needs to change. Looking at when it happens and what else you notice can help you decide what to try next.

Why Clicking Happens While Breastfeeding

Your baby uses suction, or vacuum, to stay attached and remove milk. Their tongue moves as they suck, changing the pressure inside their mouth. Ultrasound research has shown that milk flow into the mouth coincides with the tongue lowering and the vacuum increasing.

A click can happen when that suction briefly releases. Think of the popping sound when something suctioned to a surface comes loose. That comparison helps explain the sound, but it doesn’t identify which part of feeding is making suction harder to maintain.

The Latch, Tongue Movement, and Milk Flow Work Together

How your baby attaches, how their tongue moves, and how they manage the milk flow can all affect feeding. A baby who repeatedly slips toward the nipple may have difficulty maintaining their attachment. Another may pull back or lose suction when milk arrives faster than they can comfortably manage.

Lip position is part of that picture, but it isn’t the whole explanation. A lip that doesn’t look fully turned outward doesn’t establish why clicking is happening, and changing how the lip looks may not change what’s happening inside the mouth.

Is Clicking While Breastfeeding a Problem?

An occasional click during an otherwise comfortable, effective feed is different from repeated clicking alongside pain, slipping, or difficulty managing milk. The question is what the sound means in the context of your baby’s feeding.

Notice whether your baby stays attached, swallows regularly, takes comfortable breathing pauses, and gets the milk they need. Your experience matters, too. Pain, nipple damage, or repeatedly having to help your baby stay attached deserves attention even when weight gain is reassuring.

If intake is your main concern, look at feeding alongside diapers and growth. My guide to signs your newborn is getting enough milk explains how those observations fit together in the first weeks.

Why Clicking Can Come and Go

Feeds don’t happen under identical conditions. Your baby may be upset before one feed and settled before another. Your breast may feel fuller, your position may change, or your milk may flow more forcefully at certain times.

That’s why the timing is useful information. Clicking during the first rush of milk suggests something different to investigate from clicking throughout the feed with repeated slipping. Neither pattern gives you a diagnosis, but both give you a place to start.

What to Try When Your Baby Clicks

Start by watching a feed before changing several things. Notice when the clicking begins, whether it continues, and what your baby does around the same time. Then make one useful adjustment and see whether feeding becomes easier.

Check Their Body Support and Attachment

Bring your baby close, with their head and body facing the same direction so they don’t have to turn their neck to reach the breast. Support their body while allowing their head to tip back slightly. Give them time to open wide and come toward the breast chin first.

If the latch hurts or your baby keeps sliding off, gently release the suction with a clean finger before offering the breast again. If repeated attempts aren’t helping, you don’t have to keep practicing the same uncomfortable feed without support.

Notice Whether Clicking Happens With the First Rush of Milk

If clicking comes with gulping, coughing, or pulling away as milk begins flowing, try a supported, laid-back position with your baby resting against your body. Some babies manage a fast flow more comfortably this way.

Let your baby come off for a break if they need one. You can catch the initial spray in a cloth and offer the breast again when the flow settles. Fast flow doesn’t automatically mean you have an oversupply, so get individualized guidance before trying to reduce milk production.

Compare What Happens With Other Feeding Methods

If your baby also takes bottles, notice whether clicking happens there too. Clicking during both feeding methods is useful to mention during an assessment, but it still doesn’t identify one cause. Bottle nipple shape and flow introduce their own variables. My guide to clicking during bottle feeding explains what to look at.

Does Clicking Mean Your Baby Has a Tongue Tie?

No. A restrictive tongue tie can affect tongue movement and breastfeeding, but clicking alone cannot tell you whether your baby has one. Attachment, milk flow, and other feeding difficulties can produce overlapping signs.

The reverse is also true: not hearing clicking doesn’t rule out a tongue tie. Assessment needs to consider tongue movement, an examination of the mouth, an observed feed, your comfort, and milk transfer. The appearance of the tissue under the tongue is only part of that assessment.

The American Academy of Pediatrics recommends a complete breastfeeding assessment and addressing other contributing difficulties before considering treatment for symptomatic tongue tie. Clicking is a reason to ask questions about feeding, not a reason on its own to recommend a procedure.

Does Clicking Cause Gas?

You may have heard that clicking means your baby is swallowing air and that the air explains their discomfort. Swallowed air can contribute to wind, but the clicking sound doesn’t tell you how much air your baby swallowed or whether it explains their symptoms.

Squirming, arching, crying, and pulling up the legs don’t identify one cause either. Feeding difficulties and digestive discomfort can occur together without every symptom coming from a broken seal. Persistent discomfort deserves a broader look rather than assuming that stopping the click will solve everything.

What Does the Research Tell Us?

Research on burping doesn’t give us a direct answer about clicking. In one small randomized trial involving 71 mother–baby pairs, routine burping did not significantly reduce colic and was associated with more regurgitation. That doesn’t prove swallowed air never causes discomfort, but it does challenge the assumption that routinely removing air will prevent crying.

If a pause or gentle burp helps your baby settle, that’s useful. If discomfort happens after most feeds, or comes with poor feeding or growth concerns, ask your baby’s healthcare provider to assess it rather than treating everything as gas.

When Clicking Deserves a Feeding Assessment

Seek support when clicking is persistent or comes with pain, nipple damage, repeated slipping, coughing, tiring during feeds, or concerns about intake. An IBCLC with experience assessing breastfeeding and oral function can watch how your baby attaches and moves milk, then help decide whether other members of the feeding or medical team should be involved.

If transfer is uncertain, the assessment may include a weighted feed to estimate how much milk your baby takes during that session. That information belongs alongside feeding observations and growth, rather than being treated as the answer to every feeding question.

Contact your baby’s healthcare provider promptly for repeated coughing or choking, low diaper output, or poor weight gain. Difficulty breathing, color changes, or being too sleepy or weak to feed needs urgent medical attention.

Use the Sound to Understand the Feed

Clicking gives you something to notice. The next question is what happens around it: whether your baby stays attached, manages the milk, feeds comfortably, and gets what they need. Improvement may look like less slipping, more comfortable swallowing, or less pain—not simply a quieter feed.

If you’ve been told the latch looks good but feeding still hurts or feels difficult, you can ask for someone to watch a full feed and explain what they notice. Your observations belong in that conversation, and you don’t need to identify the cause before asking for help.
