The most reliable sign of an ear infection in a child is ear pain that comes on suddenly, often alongside a fever and irritability. But younger children can’t tell you their ear hurts, so you’ll need to watch for behavioral clues like tugging at the ear, trouble sleeping, and unusual fussiness. Here’s how to read the signs at every age and know when it’s time to call the pediatrician.
The Most Common Symptoms
Ear infections (called acute otitis media) happen when fluid and bacteria get trapped in the middle ear, causing swelling, redness, and pressure behind the eardrum. That pressure is what causes pain, and pain is the single most common complaint. In a child old enough to talk, you might hear “my ear hurts” and that’s your clearest signal. But ear infections produce a cluster of symptoms, not just one, so look for several of these appearing together:
- Ear pain that comes on fast, often worse when lying down
- Fever, particularly in infants and toddlers
- Irritability or crying that seems out of proportion
- Trouble sleeping or waking repeatedly through the night
- Tugging or pulling at one or both ears
- Fluid draining from the ear (yellow, white, or slightly bloody)
- Loss of balance or unusual clumsiness
- Muffled hearing or not responding to quiet sounds
- Poor feeding in babies
Fever isn’t always present, and when it is, it’s often low-grade. A temperature below 102.2°F (39°C) is typical. Fever above that threshold suggests a more severe infection and warrants a prompt call to your child’s doctor.
Signs in Babies and Toddlers
Most ear infections happen before children have learned to talk, which makes diagnosis trickier. A baby can’t point to the problem, so you’re reading behavior instead. The NIH specifically recommends watching for ear tugging, increased fussiness and crying, trouble sleeping, and reduced interest in feeding. Babies with ear infections often cry more when laid flat because the position increases pressure on the inflamed eardrum. If your baby is suddenly refusing the bottle or breast, pulling away during feeds, or arching their back while eating, the pain from swallowing and sucking could be the reason.
Balance problems are another clue that’s easy to miss. A toddler who was walking steadily and suddenly seems clumsy or unsteady may have fluid buildup affecting their inner ear. And because ear infections frequently follow a cold, pay extra attention if your baby has had a runny nose or congestion for several days and then becomes noticeably more upset.
One important threshold for infants: if your baby is under 3 months old and has a fever of 100.4°F (38°C) or higher, contact a healthcare provider right away. At that age, any fever needs evaluation regardless of the suspected cause.
Fluid in the Ear vs. Active Infection
Not every ear problem is an active infection, and understanding the difference helps you gauge urgency. An acute ear infection comes on suddenly with pain, fever, and visible distress. The eardrum is inflamed and bulging from trapped fluid and pus. This is what most parents are worried about, and it’s the type that may need antibiotics.
There’s a second, quieter condition called otitis media with effusion. This is when fluid lingers in the middle ear after an infection has already cleared, or accumulates without any infection at all. Your child might feel fullness in the ear, have slightly reduced hearing, or show no symptoms whatsoever. It’s not painful the way an acute infection is, and it usually resolves on its own over weeks to months. But if fluid keeps returning or sticks around for a long time, it can make your child more vulnerable to new infections and may affect hearing during a critical period for language development.
The practical takeaway: sudden pain plus fever usually means active infection. Muffled hearing without pain, especially after a recent cold, is more likely residual fluid.
What Happens at the Doctor’s Office
You can’t confirm an ear infection at home. A pediatrician uses a small lighted instrument called an otoscope to look at the eardrum directly. What they’re checking for is whether the eardrum is bulging outward (a sign of pressure from trapped fluid), red or inflamed, or whether fluid is visibly draining. They may also use a gentle puff of air to see how the eardrum moves. A healthy eardrum moves easily; one backed by fluid barely moves at all. Without these findings, the diagnosis isn’t ear infection, even if your child has ear pain.
This matters because ear pain has other causes, including teething, a sore throat that radiates to the ear, or swimmer’s ear (an infection of the outer ear canal, which is a completely different condition). Your pediatrician can sort these out in a single visit.
Not Every Ear Infection Needs Antibiotics
This surprises many parents, but current guidelines support a “watchful waiting” approach for certain children. The idea is to give your child’s immune system 2 to 3 days to fight off the infection before starting antibiotics. This approach applies in two situations:
- Children 6 months to 23 months with an infection in only one ear, mild pain, symptoms lasting less than 2 days, and a temperature below 102.2°F
- Children 2 years and older with an infection in one or both ears, meeting those same mild symptom criteria
Your pediatrician may write a prescription but ask you to wait before filling it, only using it if symptoms worsen or don’t improve within a few days. When antibiotics are needed, amoxicillin is the standard first choice. The course typically lasts 7 to 10 days, and it’s important to finish the full course even if your child feels better after a day or two.
Managing Pain at Home
Whether you’re in watchful waiting mode or your child is on antibiotics, managing pain matters. Acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) are both effective for ear pain. Follow the dosing instructions on the label based on your child’s weight. Ibuprofen is approved for children 6 months and older and has the added benefit of reducing inflammation. Never give aspirin to children or teenagers, especially if they’re recovering from a cold or flu, because of the risk of Reye’s syndrome, a rare but serious condition.
Numbing ear drops are available and can provide short-term relief, but they should only be used if the eardrum is intact. If you see fluid draining from your child’s ear, that may indicate a ruptured eardrum, and drops shouldn’t go in. A warm cloth held against the ear can also ease discomfort. Keeping your child’s head slightly elevated during sleep helps reduce the pressure that makes lying flat so painful.
Symptoms That Need Urgent Attention
Most ear infections resolve without complications, but a small number spread to the bone behind the ear, a condition called mastoiditis. Watch for swelling, redness, or tenderness in the bone just behind the ear. The ear itself may look like it’s sticking out more than the other side. On lighter skin, the area appears red; on darker skin tones, it can look purplish. Other warning signs include throbbing ear pain that keeps getting worse despite treatment, pus draining from the ear, worsening hearing loss, high fever, confusion, or double vision.
If your child has any of these symptoms, seek medical care promptly. Mastoiditis is treatable but requires more aggressive intervention than a standard ear infection.
Reducing the Risk of Future Infections
Some children are simply more prone to ear infections because of the size and angle of their Eustachian tubes (the tiny channels that drain the middle ear). Those tubes are shorter and more horizontal in young children, which makes drainage harder and infection easier. As kids grow, the tubes lengthen and angle downward, which is why ear infections become less common after age 3 or 4.
You can’t change anatomy, but you can reduce exposure to the triggers. Breastfeeding for at least the first six months provides antibodies that help fight off the infections that lead to ear problems. If you bottle-feed, hold your baby in a semi-upright position rather than letting them drink while lying flat, which can allow milk to flow toward the middle ear. Keep your child away from secondhand smoke, which irritates the Eustachian tubes and increases infection risk. Staying current on vaccinations also helps, particularly the pneumococcal vaccine, since the bacteria it targets is a common cause of ear infections. And frequent handwashing during cold season reduces the respiratory infections that so often precede an ear infection.
