It Shouldn’t Hurt: Why “Clicking” Sounds and Painful Nursing Are Red Flags for Feeding Dysfunction

Breastfeeding is often described as natural, instinctive, and bonding. But for many mothers, the reality feels very different. If you’ve been told that “breastfeeding hurts at first” and weeks later you’re still wincing through feeds, dealing with cracked nipples, clogged ducts, or mastitis, something important needs to be said clearly:

Pain is not a rite of passage. It’s a symptom. And if, along with the pain, you’re hearing a clicking noise when nursing, smacking sounds, or noticing that your infant fatigues easily, these are not minor quirks. They are signs of a mechanical breakdown in how your baby is feeding.

This article is for mothers who have been reassured that the latch “looks fine,” but their body and their baby are telling a different story.

When “It’s Normal” Doesn’t Feel Normal

You were prepared for tenderness in the early days. You expected an adjustment period. But no one warned you that weeks later you might still be bracing yourself before every feed.

You may be experiencing:

• Sharp or burning nipple pain

• Cracked or bleeding nipples

• Recurrent clogged ducts

• Mastitis or constant breast inflammation

• A baby who pops on and off the breast

• Audible clicking or smacking during feeds

You’ve probably heard:

• “Your latch looks great.”

• “Some babies are just noisy eaters.”

• “Breastfeeding is supposed to be uncomfortable at first.”

Here’s the truth: ongoing pain is not normal, and neither are consistent clicking sounds. When nursing hurts you or feeding sounds off, there is usually a mechanical issue in the baby’s Suck–Swallow–Breathe pattern.

Decode the Sounds: What “Clicking” Actually Means

Many mothers describe it the same way. A sharp clicking, popping, or smacking sound every few seconds while their baby nurses.

What the Clicking Noise When Nursing Really Is

That sound is not harmless. It usually means your baby is repeatedly breaking the seal between their mouth and the breast. In effective feeding, the baby’s tongue stays cupped and elevated, maintaining a gentle vacuum. When that seal is lost, the tongue snaps back into place, creating the clicking sound you hear.

Why the Seal Breaks

This breakdown commonly happens because:

• The tongue cannot stay elevated or cupped

• Oral muscle tone is low

• There is restricted tongue movement, often linked to a tongue ties

When the tongue cannot maintain suction, the baby compensates with jaw movement instead of tongue efficiency.

The Chain Reaction

This single mechanical issue creates multiple problems:

• Milk flow becomes inconsistent

• The baby swallows excess air, leading to gas, reflux, or colic

• The breast tissue experiences friction instead of stable compression

• Mothers feel pain, compression, and trauma

• Risk for pain with nursing/mastitis increases

Clicking is not just a sound. It’s a signal.

The “Lazy Eater” Myth: Fatigue Is Not Fullness

Another phrase many mothers hear is, “Your baby just gets sleepy while eating.”

But there’s an important difference between a baby who is content and one who is exhausted.

When Infants Fatigue Easily

If your baby:

• Falls asleep early in the feed

• Cannot stay alert long enough to finish

• Needs frequent feeds close together

• Appears hungry shortly after nursing

This is not because they are lazy or “milk drunk.” It’s because feeding is costing them too much energy.

The Real Effort Behind Dysfunctional Feeding

Feeding with poor mechanics is like trying to drink a thick milkshake through a tiny coffee stirrer. The effort is intense, inefficient, and tiring.

Babies who fatigue easily often:

• Burn more calories feeding than they consume

• Struggle to maintain weight gain

• Appear constantly hungry yet exhausted

• Fall asleep from effort, not satisfaction

This pattern often leads to the “poor weight gain” red flag and leaves parents confused and worried.

Why Latch Alone Isn’t the Whole Story

Most early feeding support focuses on what the latch looks like from the outside. And while latch matters, it’s only part of the picture. A latch can look acceptable while the inside mechanics are still dysfunctional.

Looking Beyond the Surface

True feeding efficiency depends on:

• Tongue elevation and cupping

• Sustained suction

• Coordinated swallowing

• Oral muscle endurance

If these pieces are not working together, no amount of repositioning will fully resolve the problem. That’s why some families feel stuck. They’ve tried every position, every pillow, every suggestion, yet the pain and clicking persist.

How We Fix the Mechanics (Not Just the Latch)

At Mequon Speech and Learning Connection, feeding therapy goes deeper than appearance. Specialists like Kim Harrison focus on what the baby’s tongue and oral muscles are actually doing during feeding.

A Different Approach

Instead of only adjusting latch, we evaluate:

• Tongue movement and elevation

• Oral muscle tone and stamina

• Ability to maintain suction

• Clarity of the suck–swallow–breathe rhythm

Gentle, Targeted Techniques

Support may include:

• Oral exercises to improve tongue elevation

• Techniques to build endurance and coordination

• Strategies that help the tongue stay cupped

• Education that empowers parents to understand the “why”

The goal is simple but powerful: efficient feeding that does not hurt you and does not exhaust your baby.

When mechanics improve, feeds often become:

• Shorter (under 30 minutes)

• Quieter

• More satisfying

• Less painful

Why Early Support Matters for Both Baby and Parent

When feeding dysfunction goes unaddressed, it affects more than just milk transfer.

For babies, it can mean:

• Reflux and discomfort

• Poor weight gain

• Feeding aversion over time

For parents, it can mean:

• Ongoing pain

• Recurrent mastitis

• Anxiety around feeding

• Dreading the next session

Feeding should be a time of connection, not fear or endurance.

A Reassuring Word to Mothers in Pain

If you are dreading the next feed, that is information worth listening to.

Your pain matters. The clicking sounds matter. Your baby’s fatigue matters.

You are not failing. You are noticing, and noticing early creates the opportunity for change.
