Ear infections are one of the most common reasons parents bring young children to the doctor, and spotting one isn’t always straightforward. Babies and toddlers can’t tell you their ear hurts, so you have to read their behavior and watch for a handful of physical signs. Here’s what to look for and what to expect if your child does have one.
Behavioral Signs in Babies and Toddlers
Since most ear infections happen before children can talk, behavior is your first clue. The classic signs include tugging or pulling at one or both ears, unusual fussiness or crying that seems out of proportion to the situation, and trouble sleeping. A child who was sleeping through the night and suddenly starts waking up crying may be dealing with ear pain that worsens when they lie flat, since that position increases pressure in the middle ear.
You might also notice your child has lost interest in eating. Sucking and swallowing change the pressure in the ear, which can make feeding painful. If your baby pulls away from the bottle or breast while crying, ear pain is a reasonable suspicion. Older toddlers may become clingier than usual or seem off-balance, since the middle ear plays a role in balance.
Physical Symptoms to Watch For
Fever is common with ear infections, though not every child runs one. A temperature under 102.2°F (39°C) with mild ear pain is considered on the milder end. For babies under 3 months, any fever at or above 100.4°F (38°C) warrants prompt medical attention regardless of the suspected cause.
Fluid or pus draining from the ear is a strong indicator. This discharge means the eardrum has likely ruptured from pressure buildup, which sounds alarming but usually heals on its own. The drainage itself often brings the child some relief because it reduces the pressure. Other physical signs include headache (in kids old enough to report it), trouble hearing or responding to sounds, and loss of appetite.
What the Doctor Actually Checks
A pediatrician diagnoses an ear infection by looking at the eardrum with a small lighted instrument called an otoscope. They’re looking for three things: signs that symptoms came on recently and suddenly, evidence of fluid trapped behind the eardrum, and signs of inflammation. A bulging, red eardrum with fluid visible behind it is the hallmark finding. In some cases, the doctor will use a small puff of air to see whether the eardrum moves normally. A healthy eardrum flexes easily; one backed by trapped fluid barely moves at all.
This exam takes only a minute or two, though keeping a squirming toddler still for it can feel longer. It’s worth getting checked rather than guessing at home, because several other conditions (teething, swimmer’s ear, even referred pain from a sore throat) can mimic ear infection symptoms.
Fluid Without Infection
Not every ear problem involves an active infection. Sometimes fluid lingers in the middle ear after an infection clears, or it builds up from congestion or allergies without any bacteria present. This is called otitis media with effusion, and it’s sneakier than an acute infection because it often causes no pain or fever. Your child might just seem like they’re not hearing well, turning the TV up louder, or asking “what?” more often.
This fluid usually resolves on its own over weeks to months. The concern is when it sticks around or keeps returning, because persistent fluid dulls hearing during a critical window for language development. If your child seems to have muffled hearing for more than a few weeks after a cold or ear infection, it’s worth a follow-up visit.
When Antibiotics Are Needed (and When They’re Not)
Not every ear infection requires antibiotics right away. For children between 6 months and 23 months with an infection in only one ear, mild pain, and a fever below 102.2°F, the doctor may recommend “watchful waiting,” which means observing for 2 to 3 days to give the immune system a chance to clear the infection on its own. The same approach applies to children 2 and older with infection in one or both ears, as long as symptoms are mild and have lasted less than 2 days.
During that waiting period, you can manage your child’s pain with children’s ibuprofen (for kids 6 months and older) or acetaminophen. Use the dosing syringe that comes with the medicine rather than a kitchen spoon, and go by your child’s weight rather than age for the most accurate dose. Ibuprofen can be given every 6 to 8 hours as needed. If symptoms worsen or don’t improve within 2 to 3 days, the doctor will typically prescribe antibiotics at that point.
For younger babies, children with high fevers, severe pain, or infections in both ears, antibiotics are usually started immediately.
What Happens If Infections Go Untreated
A single ear infection that goes unnoticed for a few days isn’t cause for panic. Most resolve, and even a ruptured eardrum typically heals within weeks. The real risks come from infections that are repeatedly ignored or chronically undertreated.
Mild, temporary hearing loss is normal during an active infection because fluid blocks sound transmission. But frequent or prolonged infections can cause permanent damage to the delicate structures responsible for hearing. In infants and toddlers, this hearing impairment during a critical developmental window can contribute to speech and language delays.
Rarer complications include mastoiditis, where the infection spreads to the bone behind the ear, causing swelling, redness, and pain in that area. An abnormal skin growth called a cholesteatoma can also develop from chronic infections or eardrum perforations, gradually eroding the small bones of the middle ear. In extremely rare cases, infection can spread to the membranes surrounding the brain. These serious outcomes are uncommon with appropriate treatment, but they’re the reason recurrent ear infections deserve consistent follow-up rather than a wait-and-see approach every time.
Patterns That Suggest a Bigger Problem
One or two ear infections a year is typical for young children. Three infections in six months, or four in a year, is generally considered recurrent. If your child hits that threshold, the pediatrician may discuss preventive options, including referral to an ear, nose, and throat specialist.
Certain factors make infections more likely: attending daycare (more exposure to colds), bottle-feeding while lying flat, exposure to cigarette smoke, and a family history of ear infections. Pacifier use after 6 months has also been linked to higher rates. You can’t eliminate every risk factor, but adjusting the ones within your control, like feeding position and smoke exposure, can reduce the frequency.
