An ear infection happens when fluid builds up behind the eardrum and becomes infected, usually during or just after a cold. They are one of the most common reasons children see a doctor, and most clear up on their own within a few days. This guide covers how to recognize one, what actually helps, when antibiotics are worth it, what to do about fluid that lingers, and when to call us.
What is an ear infection?
The common kind is a middle ear infection, called otitis media. It happens when the small tube that drains the middle ear gets blocked, usually by a cold or allergies, and fluid backs up behind the eardrum. When that fluid gets infected, it presses on the eardrum and causes pain.
Children get ear infections far more often than adults for a simple reason. The tube that drains the middle ear does not work as efficiently in a child, so fluid drains less easily. Most children have at least one ear infection by age 3, and most outgrow them as they get older and that tube matures. Almost every ear infection starts with a viral cold, which is why more exposure to colds, such as time in child care, leads to more ear infections.
It helps to know what an ear infection is not. It is not the same as swimmer's ear, which is an infection of the outer ear canal, often after water gets trapped there. And it is different from fluid that sits behind the eardrum without any infection, which is common after a cold and usually harmless. We cover that lingering fluid further down.
One thing that surprises many parents: an ear infection itself is not contagious. The colds that lead to ear infections are. So once your child feels well enough, they can go back to child care or school, even if the ear is still clearing.
How can I tell if my child has one?
The most reliable signs are ear pain and a recent cold. In a baby who cannot tell you what hurts, watch their behavior rather than any single clue.
Look for:
- Ear pain, often worse at night or when lying down.
- Fussiness, crying, or trouble sleeping in a baby or toddler who cannot describe pain.
- Fever, which shows up in about half of ear infections.
- Fluid or pus draining from the ear.
- Trouble hearing, or not responding to sound the way they usually would.
- Reduced appetite, since chewing and sucking can hurt.
Ear-tugging by itself is not a reliable sign. Many babies pull or rub their ears to self-soothe or simply because they have discovered them. A happy, playful baby who is tugging an ear most likely does not have an infection. Tugging matters more when it comes with pain, fever, or a cold.
The principle that serves parents best is to watch the child, not just the thermometer. How your child looks and acts tells you more than the exact temperature.
Keep in mind that ear pain has many causes. Teething, a sore throat, swimmer's ear, jaw pain, and pressure changes can all hurt a child's ear. We can often help by phone to decide whether your child needs to be seen, but confirming an ear infection means looking at the eardrum.
Does my child need antibiotics?
Probably not right away. Most ear infections improve on their own, and in the first day or two, controlling pain matters more than antibiotics do.
Your pediatrician is more likely to start antibiotics promptly when:
- Your child is under 2, and especially under 6 months.
- The pain or fever is severe.
- Both ears are infected in a young child.
- There is fluid or pus draining from the ear.
- Your child has a weakened immune system or another condition that raises the risk of complications.
For an older child with milder symptoms in one ear, waiting a day or two before deciding on antibiotics is a reasonable, evidence-based choice. This is sometimes called watchful waiting. The idea is simple: give the infection a short chance to clear on its own while you keep your child comfortable. If we choose this path, we will make a plan to recheck, and sometimes we will give you a prescription to hold and fill only if your child is not better in two to three days.
If antibiotics are the right call, they are usually amoxicillin. Give every dose, and finish the full course even after your child seems better. Stopping early can let the infection come back. About 1 in 5 children get mild side effects such as loose stool, an upset stomach, or a rash. Call us if that happens, and always tell us if your child has a known drug allergy. If your child is on antibiotics, a probiotic may ease stomach upset; ask us if you are interested.
Whether your child is on antibiotics or you are watching at home, expect the pain to ease within a day or two and any fever to settle within about two days. Call us if your child is not improving after two to three days, or is getting worse at any point.
We do not reach for antibiotics automatically because overusing them causes side effects and makes future infections harder to treat, without helping most ear infections heal any faster.
How can I treat the pain at home?
Pain relief is the most important part of care in the first day or two, whether or not your child takes antibiotics. Start here.
- Use acetaminophen or ibuprofen for pain and fever. Dose by weight, not age, and confirm the concentration printed on your bottle, since products vary. See our medication dosing guide, or call us if you are unsure. Give ibuprofen only if your child is at least 6 months old.
- Never give aspirin to a child or teen, because of the risk of a rare but serious condition called Reye syndrome.
- Offer extra fluids and let your child rest.
- Try a warm compress held gently against the ear.
- Raise the head a little for sleep if it helps, since pain is often worse lying flat.
- Skip cold-and-cough medicines. Decongestants and antihistamines do not help ear infections, and they are not recommended for young children.
When should I call your pediatrician?
If you think your child may have an ear infection, call us, especially with a baby. A quick conversation is often enough to decide whether they need to be seen right away, watched at home, or treated.
Reasons to call:
- Your child is under 2 and has ear pain or a fever.
- Pain or fever lasts more than two to three days or is getting worse.
- Fluid or pus is draining from the ear.
- Symptoms come back soon after finishing antibiotics.
- You are not sure the problem is the ear.
One age exception is worth stating plainly. A baby under 6 months with a fever should be seen promptly. Call us right away.
When is it an emergency?
Serious complications from ear infections are rare. A few signs, though, mean your child should be seen right away.
Seek care immediately if you notice:
- Swelling, redness, or tenderness behind the ear, or an ear that looks pushed forward or down.
- A stiff neck or a severe headache.
- A very high fever that is not improving.
- A child who is lethargic, hard to wake, or looks very ill.
- Repeated vomiting.
- Weakness on one side of the face, or new trouble with balance or walking.
The main serious complication is mastoiditis, an infection that spreads to the bone just behind the ear. It is uncommon and treatable, but it needs care quickly. Swelling or tenderness behind the ear is the sign to watch for.
What about fluid that won't go away?
It is normal for fluid to stay behind the eardrum for weeks after an infection clears, and it usually drains on its own. This is called otitis media with effusion, which simply means fluid without active infection.
This fluid is not painful and is not dangerous. It can cause mild, temporary muffled hearing, which returns to normal once the fluid clears. We typically watch it for about three months rather than treat it. Antibiotics, steroids, antihistamines, and decongestants do not clear this fluid and are not recommended for it. If the fluid lasts around three months, or if you notice your child is not hearing well, we will check their hearing and talk through the next steps.
Some children need closer follow-up when fluid lingers, including those with speech delay, developmental differences, or conditions such as Down syndrome or cleft palate. Tell us if your child has any of these, since clear hearing matters most while they are learning to talk.
Will my child need ear tubes?
Most children never need ear tubes, and they are recommended less often today than many parents expect.
We consider referral to an ear, nose, and throat specialist mainly in two situations:
- Repeated infections, often defined as three infections in six months or four in one year, with fluid still present in the ear when we examine it.
- Lingering fluid that sits behind the eardrum for about three months or longer and affects hearing.
Tubes are a short, common procedure that lets fluid drain and air reach the middle ear. They usually fall out on their own within a year or two. Most children with tubes can swim and bathe normally, and routine ear plugs or water avoidance are not needed for most of them. We will arrange a hearing test before considering surgery.
Can I prevent ear infections?
You cannot prevent every ear infection, but a few habits lower the odds, mostly by heading off the colds that cause them.
- Keep vaccines current. The pneumococcal and annual flu vaccines prevent some ear infections, because many ear infections develop after viral illnesses, including influenza.
- Breastfeed if you can. Breast milk helps protect against infections, and even partial breastfeeding helps.
- Feed your baby semi-upright, not lying flat, and do not prop a bottle. Milk can pool and reach the middle ear in a baby who is lying down.
- Keep your child away from cigarette smoke. Secondhand and thirdhand smoke raise the risk.
- Wash hands often, and manage your child's allergies if they have them.
- Limit constant pacifier use in older babies.
Common myths about ear infections
"Pulling at the ears always means an ear infection." Many babies tug or rub their ears to self-soothe or out of curiosity, with no infection at all.
"Every ear infection needs antibiotics." Most clear on their own, and in the first days, pain control matters more.
"Swimming causes ear infections." Swimming can cause swimmer's ear in the outer canal, which is a different problem from the middle ear infections that usually follow a cold.
"Decongestants or antihistamines will clear it up faster." They do not help an ear infection or the fluid left behind, and they are not recommended for young children.
"An ear infection will damage my child's hearing." Hearing is usually muffled only while fluid is present and returns to normal once it clears. Lasting damage is rare.
"If the eardrum bursts, something is seriously wrong." A small tear can happen from the pressure, and it usually drains for a day or two and heals on its own. Still, call us if you see drainage.
"Yellow or green mucus means my child needs antibiotics." Colored mucus is a normal part of a cold as it runs its course. On its own, it does not mean a bacterial infection or that antibiotics are needed.
The bottom line
Ear infections are common, painful, and almost always temporary. The two most useful things you can do are treat your child's pain early and watch how they are doing overall, not just the number on the thermometer. Many infections never need antibiotics, and the fluid that lingers afterward usually clears on its own. When you are unsure, call us, especially with a baby. It comes down to three things. Treat the pain. Watch your child. Call us if things aren't improving.
Ear infections are one of the clearest examples of why direct access to your own pediatrician matters. Because we know your child and can usually speak with you the same day, we can often use watchful waiting safely when it fits, avoid unnecessary antibiotics, and decide quickly when your child does need to be seen. Our physicians keep small panels on purpose, which is what makes that kind of access possible.
Frequently asked questions
How long does an ear infection last? Pain usually improves within a day or two, especially with pain medicine, and most infections clear within a few days to a week. Fluid behind the eardrum can take several weeks longer to fully drain, which is normal.
Can my child go to daycare or school with an ear infection? Yes, once they feel well enough. Ear infections are not contagious, though the colds that cause them can be.
Is it safe to wait before starting antibiotics? For many children over 2 with mild symptoms, yes. Watching for two to three days while keeping your child comfortable is an evidence-based option, as long as we have a plan to recheck if things do not improve.
My child's ear is draining fluid. What should I do? Call us. Drainage often means the eardrum has a small tear, which usually heals on its own, but we will want to confirm what is going on.
Do ear infections cause permanent hearing loss? Rarely. Hearing is often muffled while fluid is present and returns to normal once it clears.
How can I tell an ear infection from teething? Both can cause fussiness and ear-pulling. Ear pain that is clearly worse at night, a fever, or a recent cold point more toward an infection. When in doubt, call us.
When does my child need ear tubes? Mainly for repeated infections with fluid still present, or for fluid that lasts about three months and affects hearing. Most children never need them.
What can I give my child for ear pain? Acetaminophen or ibuprofen, dosed by weight. Give ibuprofen only if your child is at least 6 months old. Confirm the concentration on your bottle, or call us if you are unsure.
Can my child fly with an ear infection? Usually yes, but the pressure changes during takeoff and landing can be painful. Give a dose of pain medicine about half an hour before the flight, and encourage your child to swallow, suck on a pacifier, or drink during takeoff and landing. Call us first if the pain is severe or your child recently had ear surgery.
Can my child swim with an ear infection? If the eardrum is intact and nothing is draining from the ear, swimming is generally fine. Skip it if fluid or pus is draining, and call us if you are not sure.
Can my child sleep on the side with the sore ear? Yes. Let your child sleep in whatever position is most comfortable. Some prefer the sore ear up because pressure hurts, while others find gentle pressure soothing. There is no wrong sleeping position.
