Babies can’t tell you their ear hurts, so you have to read the clues. The most reliable signs of an ear infection are a combination of fussiness, trouble sleeping, fever (especially in babies under two), and changes in how your baby responds to sounds. No single symptom confirms an infection on its own, but when several show up together, particularly after a cold, an ear infection is a strong possibility.
Behavioral Signs to Watch For
The first thing most parents notice is a shift in mood. A baby with an ear infection is often irritable in a way that seems different from normal fussiness. The crying may be sharper, harder to soothe, and worse when lying flat, because that position increases pressure on the inflamed eardrum. You might find your baby fights being put down for naps or wakes repeatedly through the night, even if they’re usually a solid sleeper.
Feeding can become a battle too. Sucking and swallowing change the pressure inside the middle ear, which hurts when that space is swollen and full of fluid. Babies may latch on and then pull away crying, or refuse the bottle or breast after a few sips. If your baby suddenly loses interest in eating and seems upset during feeds, that pressure-pain connection is a likely reason.
Tugging or pulling at the ear gets a lot of attention as an ear infection sign, but on its own it’s not very reliable. Babies pull on their ears for all sorts of reasons: teething causes referred pain in the jaw and ear area, some babies find it soothing, and plenty of babies simply discover their ears and grab them out of curiosity. Ear pulling becomes more meaningful when it’s paired with a fever or follows a recent cold.
Fever and Its Role
Fever is common with ear infections, especially in younger babies and toddlers. A temperature of 100.4°F (38°C) or higher alongside other symptoms like irritability and poor sleep makes an ear infection more likely. That said, not every ear infection causes a fever, and not every fever means an ear infection. The pattern matters most: a child who had a runny nose for a few days, seemed to improve slightly, and then spikes a new fever is following the classic ear infection timeline. The cold creates congestion in the tube connecting the throat to the middle ear, fluid builds up behind the eardrum, and bacteria move in.
Physical Signs You Can See
Sometimes the body gives you a visible clue. Fluid draining from the ear is the most obvious one. If you see pus or cloudy fluid on your baby’s pillow or around the ear canal, it usually means the eardrum has ruptured under pressure from the infection. This sounds alarming, but it happens in roughly 10% of bacterial ear infections and the eardrum typically heals on its own. The drainage is often yellow or green, and it may have a noticeable odor.
Balance changes are another physical sign, though they’re easier to spot in toddlers than in younger babies. A toddler who’s been walking steadily may suddenly seem clumsy or unsteady. In younger babies, you might notice them seeming disoriented or unusually wobbly when sitting. The middle ear plays a direct role in balance, so when it’s full of infected fluid, coordination takes a hit.
Hearing Changes
Fluid trapped behind the eardrum muffles sound, so your baby may temporarily seem less responsive to quiet noises. You might notice they don’t turn toward your voice from across the room the way they usually do, or they don’t startle at sounds that would normally get their attention. This temporary hearing change usually resolves once the fluid clears, but it’s worth flagging to your pediatrician, especially if your baby has had multiple ear infections. Repeated or prolonged fluid buildup during the first few years of life can interfere with language development during a critical window for learning speech.
Ear Infection vs. Teething
This is one of the trickiest distinctions for parents because the symptoms overlap so much. Teething can cause fussiness, trouble sleeping, mild fever, drooling, and yes, ear pulling. A few things tilt the odds toward an ear infection rather than teething:
- Recent cold: Ear infections almost always follow an upper respiratory infection. If your baby had a stuffy nose or cough in the past week, an ear infection is more plausible than teething alone.
- Higher fever: Teething may cause a very slight temperature rise, but a true fever over 100.4°F points more toward infection.
- Pain that’s worse lying down: Teething discomfort doesn’t typically change with position, while ear infection pain does.
- Feeding refusal: A teething baby may chew more on the nipple but generally still eats. A baby with an ear infection often cries and pulls away during feeds.
When in doubt, a quick visit to the pediatrician can settle it. The only way to confirm an ear infection is to look at the eardrum.
How Doctors Confirm It
Your pediatrician will use a small lighted instrument called an otoscope to look inside the ear canal at the eardrum. A healthy eardrum is translucent, pearly gray, and moves freely when a small puff of air is blown against it. An infected eardrum looks red or yellow, bulges outward from the pressure of fluid behind it, and barely moves when air is puffed. The whole exam takes about 30 seconds per ear and doesn’t hurt, though your baby will probably protest being held still.
There’s no home test or app that can replace this exam. The behavioral signs give you good reason to call the doctor, but the eardrum check is what separates a definite ear infection from congestion, teething, or a virus that’s making your baby miserable for other reasons.
What Makes Some Babies More Prone
Ear infections are extremely common in young children. The tube that drains the middle ear into the throat is shorter and more horizontal in babies than in adults, which means it clogs easily and doesn’t drain well. Some factors increase the risk further:
- Daycare attendance: More exposure to colds means more opportunities for fluid to build up behind the eardrum.
- Secondhand smoke: Smoke irritates the lining of the drainage tube, making it swell and trap fluid.
- Bottle feeding while lying flat: Liquid can flow toward the middle ear when a baby drinks on their back. Holding your baby at a slight angle during feeds reduces this.
- Pacifier use: Studies have linked prolonged pacifier use to slightly higher rates of ear infections, possibly because the sucking motion affects pressure in the middle ear.
- Age: Babies between 6 and 18 months get the most ear infections. The anatomy of the ear gradually changes as children grow, and infections become less frequent after age three.
What Happens After Diagnosis
Not every ear infection needs antibiotics right away. For babies over six months with mild symptoms in one ear, many pediatricians recommend a “watchful waiting” approach for 48 to 72 hours, since a significant number of ear infections clear on their own. You can manage pain with age-appropriate doses of infant pain reliever during this window. If symptoms worsen or don’t improve, antibiotics are the next step.
Babies under six months, children with high fevers, and those with infections in both ears are more likely to be prescribed antibiotics from the start. A typical course runs 7 to 10 days. Most children start feeling better within two to three days of starting treatment, though it’s important to finish the full course.
If your child keeps getting ear infections (three or more in six months, or four or more in a year), your pediatrician may refer you to an ear, nose, and throat specialist to discuss small tubes placed in the eardrums. These tiny tubes help fluid drain and prevent the buildup that leads to infection. The procedure is one of the most common childhood surgeries, takes about 15 minutes, and most kids go home the same day.
