If your baby’s ears smell bad, first check whether the smell comes from the skin behind the ear or from fluid at the ear-canal opening. Gently clean and dry only intact outside skin. Smelly drainage, pain, a sore or weeping fold, or a baby who seems unwell needs medical advice. Do not put cotton buds, oil or home remedies inside the ear.
I’d look at your baby before reaching for a cloth: are they feeding comfortably, waking normally and acting like themselves? Then look at the outside of the ear in good light. You do not need to identify the smell or name an infection to make a useful call.
When to get help for a smelly baby ear
A smell on an otherwise comfortable baby’s intact skin is different from swelling, drainage or illness. Use the signs below to decide how quickly to seek help. If you cannot tell where fluid is coming from, describe that uncertainty to your baby’s clinician instead of cleaning deeper to find out.
Behind the ear, at the opening, or a baby who feels unwell?
The outside fold is the crease where the back of the ear meets the head. The canal opening is the small entrance you can see from the front. Looking at those two places is enough for a parent’s first check. A clinician uses an appropriate instrument to examine farther inside.
Where you notice it changes what you do
Behind the ear → look at the skin.
Is there surface residue, or is the fold cracked, wet, hot or sore? Intact skin can have a gentle outside wipe and careful drying. Damaged or persistently smelly skin needs advice.
At the canal opening → notice drainage.
Fluid that reappears or stains clothing is worth describing. Do not plug the opening, scrape out material or use its color to diagnose an infection.
The whole baby → check comfort and feeding.
Temperature, alertness, feeds and wet diapers belong in the same decision. A clean-looking ear does not cancel concerning symptoms.
Support your baby comfortably while they are awake. You can gently move the outer ear just enough to see the crease, but stop if that hurts or your baby strongly resists. Do not pull harder to uncover the “real” source. Pain with ordinary handling is useful information for the clinician.
Take one quick look at the other side for comparison. Note which side has the smell and whether either fold looks wet or irritated. I would describe what I can actually see: “There is a damp patch behind the left ear,” rather than “There is definitely an infection.” That leaves room for an examination to answer the medical question.
What can make the skin behind a baby’s ear smell?
Surface residue and a damp fold
During a feed, bath or change of clothes, you may notice milk residue, spit-up or dampness near the ear. If the material is on intact outside skin and your baby is comfortable, clean that visible area gently and dry it. The NHS recommends cleaning around babies’ ears while keeping cotton buds and other cleaning inside the ear out of the routine.
A fold that is easy to miss is not evidence that you have failed at caring for your baby. I’d use the discovery as a reminder to include that little crease in ordinary washing, without turning it into a repeated inspection. More rubbing is not automatically better cleaning. Once the visible residue is gone and the skin is dry, leave it alone.
Check what is touching the area, too. A damp neckline or bib can be changed without adding another skin product. Keep bibs off for sleep. If the odor returns despite gentle care, or the skin looks raw, arrange advice rather than escalating to stronger soap. Tell the clinician whether the smell disappears after cleaning and how quickly it comes back.
Cradle cap or inflamed skin in the crease
Infant seborrhoeic dermatitis, often called cradle cap, can affect more than the scalp, including behind the ears and other folds. Greasy scales may be part of that pattern. Eczema UK advises getting medical advice when affected skin becomes hot, unusually smelly or weepy because infection can complicate the skin problem. A photograph cannot reliably settle that distinction. Eczema UK: infant seborrhoeic dermatitis.
If you also see scalp scales, our cradle cap guide explains what to notice and discuss. Keep scalp treatments separate from ear care: advice about loosening scalp scales does not mean putting oil or shampoo in an ear canal. Do not peel scales off the fold or try to scrub it smooth.
For a baby with an existing skin-care prescription, ask whether that plan applies to the ear crease before extending it there. Say whether the skin is dry, cracked, moist or bleeding and whether touching it changes your baby’s behavior. Have the product name ready. “The cream we used before” can mean different things to different caregivers.
Is it earwax or drainage?
Wax can be yellow, orange or brown, and wet wax can resemble discharge. Fluid from an infection may look cloudy or pus-like. These descriptions help you report what you see, but color and smell cannot tell you exactly what is happening. Clear moisture just after a bath can be water; fluid that continues, recurs or accompanies symptoms needs assessment.
The AAP explains that an infected middle ear can sometimes drain through an opening in the eardrum. A baby may seem less uncomfortable after drainage begins, but that improvement does not prove the problem is over. New drainage is a reason to contact the clinician, not a sign that cleaning solved it. AAP: ear infection symptoms.
Leave material inside the canal alone. If fluid is already on the outer ear, you can gently wipe that outside surface without pushing the cloth into the opening. Do not use a cotton bud to collect a sample. If a clinician wants a photo, show the visible outside area and explain when the fluid appeared.
I would skip trying to classify the odor as “cheesy,” “fishy” or another precise smell. Those words are subjective and do not choose the treatment. More useful details are which side, where the moisture appears, whether it returns, your baby’s age and whether feeding or comfort has changed.
How to clean the outside safely
This short routine is for intact outer skin on a comfortable baby. It is not treatment for drainage, an injured ear or a sore, weeping rash. Follow your clinician’s instructions if your baby has ear tubes, a known eardrum problem or a current ear treatment.
Prepare → wipe outside → pat dry
- Prepare first. Have clean lukewarm water, a soft clean cloth or fresh cotton wool, and something clean for drying within reach. Keep your baby supported and supervised.
- Use a gentle outside wipe. Clean visible skin around the ear and the crease behind it. Keep the cloth or cotton wool outside the canal. Use a clean part for the other ear.
- Pat the fold dry. Avoid scrubbing, picking or leaving the crease wet. Stop if ordinary gentle contact seems painful.
The NHS’s washing and bathing guidance covers outside-ear cleaning and careful drying. A full bath is not necessary just to clean a small patch of intact skin.
Do not put soap, peroxide, alcohol, essential oils, breast milk or homemade mixtures into the ear. Avoid suction gadgets and ear-cleaning tools. If wax seems to be the issue, ask the clinician whether anything needs to be done. Removing every bit you can see is not a goal for infant ear care.
If your baby wriggles, pause rather than trying to finish a “perfect” clean. Put them somewhere safe while you reset the supplies, or ask another awake adult to help with support. You should not need to restrain your baby for deep cleaning because deep cleaning is not part of this routine.
Afterward, remember what changed. Did the visible residue wipe away? Is the fold comfortable and dry, or still moist and sore? That observation helps you decide whether a simple outside-care step was enough or whether you need advice. Do not repeat the wipe every few minutes to check for an answer.
Can my baby have an ear infection without a fever?
Fever is one possible symptom, not a requirement for an ear problem. Babies may show discomfort through crying, changes during feeds or disrupted sleep. Ear pulling by itself can also be ordinary exploration or self-soothing. Neither a normal temperature nor a tug on the ear gives you a diagnosis. AAP: ear infection information.
There are different places an infection can occur. The middle ear is behind the eardrum; the outer ear canal is a different area. Treatment depends on what the examination shows. That is why advice for an older child’s swimmer’s ear, or a prescription from a previous episode, may be wrong for this baby’s symptoms. NHS: ear infections.
Arrange an examination when an infection is suspected, especially for a baby under 12 months. Tell the clinician about recent colds, drainage, feeding changes and anything already put in the ear. If there are ear tubes or previous ear surgery, mention that early rather than assuming it is already visible in the appointment notes.
Why one smelly ear still matters
One-sided odor does not prove either an infection or harmless residue. Check the outside location and symptoms in the same way you would for both ears. A foreign object is another possibility in a child who could place something there; do not probe or flush to investigate. A possible button battery needs emergency assessment because it can cause serious injury. Children’s Minnesota: objects in the ear.
If the same ear repeatedly smells or drains, keep a short timeline and arrange follow-up even if the baby seems comfortable between episodes. Write down when the area looks completely normal as well as when it changes. Repeatedly cleaning away the visible evidence can make the pattern harder to describe.
Swelling behind the ear is a different concern
Pain, tenderness or swelling behind the ear, especially with an ear pushed outward, needs urgent medical assessment. Mastoiditis is a serious infection of the bone behind the ear, and these can be warning signs. Smell alone does not mean mastoiditis; the point is to act on swelling and illness instead of treating them as a dirty fold. NHS: mastoiditis.
Watch: a pediatrician explains ear infections
In UNICEF’s “How to care for your baby’s ear infection,” pediatrician Dr. Alok Patel explains symptoms, examination and treatment decisions. The useful takeaway is that a clinician examines the eardrum and decides the care plan. The video’s discussion of watching and waiting applies when a clinician recommends it; it is not a reason to wait on new smelly drainage in a baby.
Watch UNICEF’s video on YouTube if the player does not load. The written steps here remain available without watching.
Do smelly ears need drops or antibiotics?
That decision belongs to the clinician after assessment. Not every ear infection needs antibiotics, and an ear smell does not establish an infection at all. If medicine is prescribed, use the specific medicine, dose and duration directed for this episode. Do not use leftover antibiotics or another child’s drops.
Before using any nonprescription ear drops, tell the clinician whether there is drainage, an ear tube or a possible eardrum injury. Do not assume a product labeled for wax is suitable. If there could be a battery in the ear, Poison Control specifically warns against adding drops before examination. Poison Control: button battery guidance.
Ask for a clear follow-up point: what improvement should you expect, when should you call if it is not happening, and which new signs need immediate care? Put those instructions with the medicine rather than relying on memory during a difficult night. If your baby vomits a dose or you are unsure how much went in, ask the prescriber or pharmacist what to do.
For pain relief, ask what is appropriate for your baby’s age and weight. Young-infant fever needs assessment before you try to manage it at home. An ear thermometer is not reliable for babies younger than 6 months, according to the AAP; ask how to measure temperature correctly if you are unsure.
Make the plan clear before you leave
If the clinician recommends observation, ask what that means for your baby specifically. Does the office want a call tomorrow, an examination if drainage continues, or another check after treatment? A general statement that some ear infections improve without antibiotics is not an individual follow-up plan. Write down the actual instructions you receive.
Also ask about bathing and keeping the ear dry during this episode. Advice can differ when there is drainage, an ear tube or a particular prescription. Do not improvise a plug for the canal. If the instructions are unclear, have the clinician or pharmacist explain how and where to apply the prescribed medicine before the next dose is due.
Mention any change in how your baby responds to familiar voices or sounds. You do not need to test hearing by clapping close to the ear or making louder noises. Tell the clinician what seemed different during ordinary interaction and ask whether it changes the follow-up. An ear visit is a good time to raise that observation, even if the odor was what first caught your attention.
What to tell the pediatrician
I’d make a short note before the call, particularly if another caregiver will speak with the office. You do not need an elaborate symptom diary. A few concrete observations make it easier to explain what changed and help prevent a tired adult from accidentally leaving out the baby’s age or a recent fever.
A ready-to-use call note
“My baby is ___ old. I noticed the smell ___ ago, on the ___ side. It seems to come from ___ . I can see ___ . Their temperature is ___, measured with ___ . Feeding and wet diapers are ___ . They seem ___ . We have used ___ on or near the ear.”
Add ear tubes, a recent illness, prescribed medicines or an injury. “I cannot tell whether this is wax or drainage” is a useful observation too.
Describe visible changes in ordinary words. “The fold looks shiny and wet” is clearer than choosing a rash name you found online. If the fluid has marked a neckline or sheet, note when that happened. Keep a photo only if it can be taken without delaying care or making your baby uncomfortable.
For a recurring problem, include what helped temporarily and what did not. Separate a treatment prescribed by a clinician from something tried at home. There is no benefit to leaving out a product because you worry it was the wrong choice; that information helps the clinician give you the right next instructions.
If you are waiting for a callback, keep your phone available and follow any triage instructions already given. Tell the office if symptoms change while you wait. An earlier message about a comfortable baby with an odor does not describe the situation if fever, swelling or poor feeding develops afterward.
When another adult takes your baby to the appointment, send the short note and medicine details with them. Ask them to bring back the diagnosis, any treatment instructions and the next contact point in writing. That way, everyone caring for the baby is working from the same plan rather than a secondhand summary of “the ear looked okay.”
How to handle bedtime while an ear problem is being assessed
If discomfort has changed your baby’s feeds or sleep, care and comfort come before a new bedtime plan. Follow the clinician’s treatment instructions and offer the usual feeds. Call back if drinking becomes difficult, wet diapers drop or your baby seems worse. Do not interpret an unsettled night as a sleep habit you must correct.
Keep the evening manageable: change damp clothing, dim the room when appropriate and use a familiar quiet song or book. Skip an optional bath if it makes care harder. A bath is not a treatment for ear odor or an infection; our guide to baths and baby sleep discusses when bathing fits a routine and when a simpler evening makes sense.
An awake adult can hold and comfort a baby, but the sleep space should remain firm, flat and clear. Put your baby on their back in their own approved crib or bassinet, with a fitted sheet and no loose bedding. Do not raise the mattress, add a wedge or use a pillow to keep the sore side up. If you are getting drowsy while holding your baby, transfer them to their sleep space. AAP: safe sleep.
I would keep overnight instructions visible for whoever takes the next shift: the advice already received, the time of any prescribed medicine, and what change means another call. That avoids waking your baby for repeated ear checks simply because two adults have different information. Do not hide concerning symptoms behind a goal of protecting the sleep schedule.
Once your baby is comfortable and the medical plan is clear, you can return gradually to ordinary bedtime choices. Our guide to choosing a baby’s bedtime can help with that broader routine. A rough night during illness does not require you to solve the entire sleep pattern at once.
An optional cloth, if you need one
A clean, soft cloth you already own is enough for intact outside-ear skin. You do not need a special ear-cleaning kit. If you need extra washcloths, Burt’s Bees Baby’s Golden Bee cotton washcloth three-pack is one practical option: the manufacturer describes a small cloth with smooth and looped terry sides.
Choose it for gentle outside washing, not to treat odor, dermatitis or infection. Keep it outside the canal, wash it between uses and stop if contact is painful. A bulk purchase or an ear tool does not make this small care step more effective.

If the smell comes back
Check the location again without digging. A recurring damp fold and recurring canal drainage are different stories to bring to an appointment. Note whether the skin ever looks fully normal, whether the same side is involved and whether the return follows a feed, bath or change of clothing. These details organize the conversation; they do not prove the cause.
Arrange advice for persistent or repeated odor despite gentle outside care, and use the urgent signs above whenever new symptoms appear. I would not keep adding products to cover the smell. Your job is to notice the change and help your baby get appropriate care. You do not have to solve an ear diagnosis in the nursery.

Thank you so much for this video! I had no idea about the dangers of baby swings :O
Hi Mary-Ann. I have a question: Is method in any way similar to the ones recommended by Dr Bucknam, Dr. Weissbluth or Dr. Karp? We tried those but none of them help.
Hi Regina, thank you for your question. The short answer is no. The techniques I share in my guide are based on newest scientific research and this is why I have never seen any approach similar to the one I recommend.
This method really works! I tried it on my son Jesus and after just one week he went from waking up more than 5 times a night to waking up just once or twice. You are a lifesaver, Mary-Ann!
I'm truly impressed with how much information you share in your video. And all for free! I can feel that you truly care about mothers like myself, and that's hard to find these days. I have recommended your site to several of my friends already.
Mary-Ann, our child suffers from autism. Is your approach still suited?
Chloe, I made sure my method can be used with any child, even babies who are special like yours. Please note that I'm not a doctor and that I always advice to consult with your physician because nothing is more important than the safety and well-being of your love.
Hallo Mary-Ann, I'm from Germany. Do you have your guide in German?
Hello Heide, we do! Normally you should already see our video in German. If not, please contact our support so they can guide you
Thenk you for your answer, Mary-Ann!
I just completed your approach and I have to say, it worked almost too well. Yes, it took a bit of getting used to with your bedtime routine but the difference is huge. My son George used to take 1 hours to go down and now he's firmly asleep in no more than 10 minutes! You're the best!
It seems I'm the only man watching this video, lol! What you shared about the 'emotional backpack' made immediate sense to me and I can't wait to help my little girl Mila to unpack it!
Hey there, just discovered your site and this really sounds different. Just wanted to say thanks for sharing :)
For everyone who's still thinking about getting Mary-Ann's guide I want to advise you to go ahead. I wasn't sure myself but now I'm so thankful I invested in this program. It made a huge difference in our life as a family and yes, my baby girl does sleep through the night now.
