The most reliable sign of an ear infection in a child is pain in and around the ear, but younger kids often can’t tell you that directly. Instead, you’ll notice behavioral changes: fussiness that seems out of proportion, trouble sleeping, or a hand constantly going to one ear. Most ear infections clear up within about three days, but knowing what to look for helps you decide how quickly your child needs to be seen.
Signs in Babies and Toddlers
Children under two or three can’t point to their ear and say it hurts, so you have to read the clues. The most common behavioral signs include:
- Tugging or pulling at the ear. This is the classic move, though some kids do it when teething too. It’s more meaningful when combined with other symptoms.
- Unusual crying and irritability. The pain from fluid pressing against the eardrum tends to worsen when lying down, so a child who seems fine during the day but falls apart at bedtime or during naps is a common pattern.
- Difficulty sleeping. Lying flat increases pressure in the middle ear, making nighttime miserable.
- Feeding problems. Sucking and swallowing change pressure in the ear, which can make bottle-feeding or breastfeeding painful. A baby who suddenly refuses to eat or pulls away crying mid-feed may be dealing with ear pain.
- Clumsiness or balance problems. The middle ear plays a role in balance, so you might notice a toddler who’s wobblier than usual or falling more often.
- Trouble hearing or responding to sounds. Fluid behind the eardrum muffles sound. If your child isn’t turning toward their name or seems to need the TV louder, that’s worth noting.
None of these signs alone confirms an ear infection, but two or three happening together, especially after a cold, paint a pretty clear picture.
Physical Symptoms You Can Spot
Fever is common with ear infections, particularly in babies and younger toddlers. A temperature of 102.2°F (39°C) or higher alongside ear-related behavior is a strong signal. Not every ear infection causes fever, though. Older children sometimes have infections with no temperature change at all.
Fluid or pus draining from the ear is another visible sign. This happens when pressure builds up enough to create a small hole in the eardrum. It sounds alarming, but the drainage itself often brings pain relief, and the eardrum typically heals on its own. The fluid may be yellow, white, or slightly bloody.
If your baby is under 3 months old and has a fever of 100.4°F (38°C) or higher, that warrants prompt medical attention regardless of whether you suspect an ear infection. At that age, any fever needs evaluation.
What Older Kids Will Tell You
Children who can talk make this easier. They’ll complain about ear pain, a feeling of fullness or pressure, or say things sound “weird” or muffled. Some describe a ringing or buzzing. The pain often starts suddenly and can be sharp or throbbing. It’s usually worse at night.
Older kids might also mention that it hurts to chew, since the jaw joint sits right next to the ear canal. If your child had a cold or upper respiratory infection in the past week or two and now has ear pain, an ear infection is the most likely explanation. The tubes that drain the middle ear into the throat get swollen and blocked during a cold, trapping fluid that then becomes a breeding ground for bacteria.
Why Some Kids Get Them More Often
Children between 6 months and 2 years are especially prone to ear infections because the drainage tubes connecting their middle ear to the throat are shorter, narrower, and more horizontal than in older kids or adults. That anatomy makes it easier for fluid to get trapped.
Beyond age, several factors increase the odds. Kids in group daycare settings are exposed to more colds, which means more opportunities for fluid buildup. Exposure to secondhand smoke irritates the lining of the drainage tubes. Bottle-feeding while lying flat can allow milk to flow toward the middle ear. And children who had their first ear infection before 6 months of age tend to get more of them as they grow.
What the Doctor Looks For
You can’t confirm an ear infection at home. The diagnosis requires someone to look at the eardrum with an otoscope, the small handheld tool with a light and magnifying lens. A doctor is checking for specific things: whether the eardrum is bulging outward from fluid pressure, whether it’s red or inflamed, and whether there’s visible pus behind it. They may also use a small puff of air to test whether the eardrum moves normally. An infected ear with trapped fluid behind it won’t move the way it should.
Home otoscopes and smartphone-attached cameras are available, but research shows parents and physicians often disagree on what the images reveal. In one study, there was low agreement between images parents captured and what a specialist saw during a standard exam. Diagnosing an ear infection is genuinely harder than it looks, because a child who’s been crying will also have a red eardrum, and earwax frequently blocks the view. These tools may have a role for families already monitoring ear tubes, but they’re not reliable for diagnosing a new infection.
Not Every Ear Infection Needs Antibiotics
This surprises many parents, but current guidelines from the American Academy of Pediatrics recommend a “watchful waiting” approach for mild, uncomplicated ear infections in children 6 months and older. If the pain is mild, has lasted less than 48 hours, and the fever is below 102.2°F, your doctor may suggest managing symptoms at home for two to three days before prescribing antibiotics. Most infections resolve on their own in about three days.
Antibiotics are recommended upfront when symptoms are more severe: a fever at or above 102.2°F, moderate to severe ear pain, or pain that’s already lasted more than 48 hours. Children under 6 months with a confirmed ear infection generally receive antibiotics right away.
During the waiting period, over-the-counter pain relievers appropriate for your child’s age can help manage discomfort. Warm compresses held against the ear also provide some relief. If symptoms aren’t improving after three days, or they get worse at any point, that’s the signal to follow up.
Signs of a Serious Complication
Ear infection complications are rare, but they do happen. The infection can occasionally spread to the bone behind the ear (you’d notice swelling, redness, or tenderness behind the ear that pushes it forward). In very rare cases, bacteria from an ear infection can reach the membranes surrounding the brain.
Get immediate medical care if your child develops any of these alongside an ear infection: a sudden high fever, stiff neck, persistent vomiting, confusion or unusual sleepiness, seizures, or a bulging soft spot on an infant’s head. These are not typical ear infection symptoms and need urgent evaluation.
Fluid Can Linger After the Infection Clears
One thing that catches parents off guard is that fluid often remains behind the eardrum for weeks or even months after the infection itself has resolved. Your child may seem perfectly fine but still have muffled hearing during this period. This is normal and usually resolves without treatment, but it’s worth mentioning to your pediatrician if it seems to affect your child’s speech development or hearing over time. Persistent fluid that doesn’t clear on its own is one of the reasons doctors sometimes recommend ear tubes for children with frequent infections.
