The most reliable signs that your child has an ear infection are ear pain, fever, and fussiness that come on suddenly, often during or right after a cold. Children older than two or three will usually tell you their ear hurts. For babies and toddlers who can’t say that yet, you’ll need to watch for behavioral clues like tugging at the ear, unusual crying, and trouble sleeping. Here’s how to read those signals and know when it’s time to call your pediatrician.
The Key Symptoms to Watch For
Ear infections in children typically produce a cluster of symptoms rather than just one. The core signs include ear pain, fever, irritability, difficulty sleeping, and sometimes fluid draining from the ear. A fever of 101°F or higher alongside ear pulling is a strong indicator you’re dealing with an infection rather than something else like teething.
Not every child will have all of these at once. Some kids spike a high fever with little fussiness, while others are clearly in pain but barely register a temperature. The combination matters more than any single symptom. If your child has two or three of these signs together, especially following a cold or upper respiratory illness, an ear infection is a likely explanation.
Signs in Babies and Toddlers
Babies can’t point to their ear and tell you what’s wrong, so you have to look for indirect cues. The National Institute on Deafness and Other Communication Disorders lists these as the key behavioral signs in young children:
- Tugging or pulling at one or both ears. This is one of the most recognizable signs, though some babies do this out of habit or curiosity. It becomes meaningful when paired with other symptoms.
- Unusual fussiness and crying. The pain from an ear infection often worsens when a child lies down, because the position increases pressure on the eardrum. You may notice your baby is fine upright but miserable in the crib.
- Trouble sleeping. For the same reason, nighttime and naptime often become a battle. A child who normally sleeps well but suddenly wakes crying repeatedly may be dealing with ear pain.
- Fever. Fever is especially common in infants and younger toddlers with ear infections.
- Problems with balance or clumsiness. The middle ear helps control balance. Toddlers who are walking may seem unsteady or fall more than usual.
- Not responding to quiet sounds. Fluid buildup in the middle ear dampens sound. You might notice your child doesn’t turn toward your voice or needs the TV louder than normal.
Feeding can also be a clue. Sucking and swallowing change the pressure in the middle ear, which can make pain worse. A baby who suddenly refuses the breast or bottle, or cries while feeding, may be telling you something about their ears.
Teething vs. Ear Infection
This is one of the most common sources of confusion for parents, and for good reason. Both teething and ear infections cause fussiness, disrupted sleep, and sometimes a low-grade fever. Both can make a baby pull at the side of their face.
The clearest difference is the fever. Teething can produce a mild temperature bump, but a fever of 101°F or higher points toward infection. Teething also causes drooling, swollen gums, and a desire to chew on everything, none of which are ear infection symptoms. And teething discomfort tends to come and go over days or weeks, while ear infection pain escalates over hours and doesn’t let up. If your child’s symptoms haven’t improved after three days, or if a real fever develops, it’s worth calling your pediatrician.
What the Doctor Looks For
You can’t confirm an ear infection at home. A pediatrician uses a lighted instrument called an otoscope to look at the eardrum directly. The key finding is a red, bulging eardrum, which signals that infected fluid has built up behind it. In some cases, the doctor may also use a small puff of air to check whether the eardrum moves normally. A healthy eardrum flexes easily; one backed by fluid stays rigid.
According to the American Academy of Pediatrics diagnostic guidelines, the most specific sign of an acute ear infection is a bulging eardrum. Other criteria include new drainage from the ear, recent onset of pain with mild bulging, and intense redness of the eardrum. These are things only a trained clinician can assess, which is why an office visit matters even when you’re fairly sure what’s going on.
Two Types of Ear Fluid
Not all fluid behind the eardrum means an active infection. There are two distinct conditions worth understanding because they look different and are handled differently.
An acute ear infection involves bacteria or viruses actively multiplying in trapped fluid. This is the painful one, with fever, crying, and obvious distress. It typically follows a cold and comes on fast.
The second type is fluid that lingers after the infection itself has cleared. This is extremely common in young children. The fluid can sit behind the eardrum for weeks or even months without causing pain or fever. The main symptom is mild hearing loss, often described as a feeling of fullness in the ear. Hearing loss is actually the most frequently reported symptom of this condition. Your child might not seem to hear you from across the room, or they may turn up the volume on devices. This fluid usually resolves on its own, but if it persists for several months, your pediatrician will want to monitor your child’s hearing.
Temporary Hearing Changes
Mild hearing loss during an ear infection is normal and almost always temporary. Fluid in the middle ear physically blocks sound vibrations from reaching the inner ear, so everything sounds muffled to your child. Once the fluid drains, hearing returns to normal.
The concern is with repeated infections or fluid that never fully clears. In young children, even mild hearing loss during a critical window for language development can affect speech. If your child has had several ear infections in a short period, or if you notice they’re not responding to sounds the way they used to even between infections, bring it up with your pediatrician. Monitoring hearing over time is more important than worrying about any single episode.
What Increases Your Child’s Risk
Some children get ear infections far more often than others, and it’s not random. Age is the biggest factor: the tubes that drain the middle ear are shorter and more horizontal in young children, making it easier for fluid and bacteria to get trapped. Most kids outgrow frequent ear infections by age three or four as these tubes grow and angle downward.
Other factors that raise risk include attending daycare or group childcare (more exposure to colds means more opportunity for ear infections), exposure to cigarette smoke, and bottle-feeding while lying flat. Feeding a baby in a more upright position helps prevent milk from flowing toward the middle ear. Children who use pacifiers also tend to get slightly more ear infections, though the mechanism isn’t entirely clear.
When Symptoms Need Urgent Attention
Most ear infections are not emergencies, but a few situations call for prompt medical attention. Contact your pediatrician right away if your child has a fever of 102.2°F (39°C) or higher, if you see pus or fluid draining from the ear, or if symptoms are getting worse rather than better after two to three days. For infants under three months old, any fever of 100.4°F or higher warrants a call regardless of the suspected cause.
Also watch for swelling or redness behind the ear, which can indicate the infection has spread to the bone. This is rare but requires immediate care. Similarly, if your child seems unusually lethargic, has a stiff neck, or is difficult to wake, seek medical attention right away.
