Babies with ear infections almost always show behavioral changes before anything else becomes obvious. Because infants can’t tell you their ear hurts, you have to read the clues: tugging or pulling at the ear, unusual fussiness, trouble sleeping, and sometimes fever. These signs together, especially following a cold, strongly suggest an ear infection.
Behavioral Signs to Watch For
The most recognizable signal is a baby repeatedly tugging or pulling at one or both ears. On its own, ear tugging can be normal exploration, but combined with other symptoms it becomes much more telling. Here’s what to look for:
- Tugging or pulling the ear, particularly on one side
- Crying and irritability that seems out of proportion or unexplained
- Difficulty sleeping, since lying flat increases pressure on the middle ear
- Fever, which is more common in younger babies with ear infections
- Fluid draining from the ear, which means the eardrum has ruptured (this sounds alarming but often relieves pain quickly)
- Loss of balance or clumsiness in babies who are crawling or walking
- Reduced response to sounds, like not turning toward your voice as usual
- Refusing to eat, because sucking and swallowing change the pressure inside the ear and can make pain worse
Most ear infections develop a few days into a cold or upper respiratory infection. If your baby has been congested and then suddenly becomes more irritable, that timing alone is a strong clue.
Why Babies Get Ear Infections So Easily
The anatomy of a baby’s ear is essentially set up for infection. The eustachian tube, which connects the back of the throat to the middle ear, is shorter, narrower, and more horizontal in infants than in adults. That means fluid from a cold or congestion doesn’t drain well. It pools in the middle ear, creating a warm, wet environment where bacteria thrive.
As children grow, the tube lengthens and tilts to a steeper angle, which is why ear infections become far less common after age three or four. But in the first two years of life, many kids will have at least one.
Feeding Position Matters
If you bottle-feed, the angle you hold your baby makes a real difference. Feeding in a fully horizontal position allows liquid to flow back up through the eustachian tube into the middle ear. That backflow introduces bacteria and increases infection risk. Keeping your baby’s head elevated above their stomach during feeds, even at a slight angle, helps prevent this. Breastfeeding naturally positions babies more upright, which is one reason it’s associated with fewer ear infections.
What Happens at the Doctor’s Office
A pediatrician diagnoses an ear infection by looking at the eardrum with a small lighted instrument called an otoscope. A healthy eardrum is translucent and pearly gray. An infected one looks red, swollen, and bulging outward from the pressure of trapped fluid behind it. In some cases, the doctor uses a small puff of air to check whether the eardrum moves normally. An infected eardrum barely moves because fluid is pressing against it from the inside.
This exam takes about 30 seconds per ear. It can be uncomfortable for a squirmy baby, but it isn’t painful.
Not Every Ear Infection Needs Antibiotics
This surprises many parents, but current pediatric guidelines call for a “watch and wait” approach in certain cases. The decision depends on your child’s age, whether one or both ears are affected, and how severe the symptoms are.
Babies under six months with a confirmed ear infection are treated with antibiotics right away. Between six months and two years, the approach depends on whether the infection is in one ear or both. A bilateral infection (both ears) gets immediate treatment, while a unilateral infection in an otherwise well child may be monitored for 48 to 72 hours to see if it improves on its own. For children two and older with mild symptoms, observation is the standard first step.
Severe symptoms change the equation at any age. If your child has a fever of 102.2°F (39°C) or higher, moderate to severe ear pain, or symptoms that have lasted more than 48 hours, antibiotics are started immediately.
Managing Pain at Home
Whether or not your baby ends up on antibiotics, pain relief matters. Acetaminophen (Tylenol) is safe for babies three months and older, given every four to six hours as needed, up to five doses in 24 hours. Ibuprofen (Motrin, Advil) is an option for babies six months and older, given every six to eight hours, up to four doses per day. Both are dosed by weight, not age, so check the packaging carefully or ask your pediatrician for the right amount.
A warm (not hot) washcloth held gently against the ear can also provide comfort. Keeping your baby’s head slightly elevated during sleep helps fluid drain and reduces pressure on the eardrum.
Symptoms That Need Prompt Attention
Most ear infections are manageable and resolve within a few days, but certain signs warrant a same-day call or visit. A fever of 102.2°F or higher, pus or fluid draining from the ear, symptoms that worsen instead of improving, or noticeable hearing changes all call for medical evaluation. For babies under three months, any fever of 100.4°F (38°C) or higher is reason to contact your pediatrician immediately, regardless of whether you suspect an ear infection.
Repeated Infections and Hearing
A single ear infection rarely causes lasting problems. But infections that keep coming back, or persistent fluid that lingers in the middle ear for weeks, can temporarily reduce hearing. Even mild, temporary hearing loss during the first two years of life can delay speech and language development. Babies learn to talk by listening, so even a partial reduction in what they hear during a critical window matters.
If your child has had three or more ear infections in six months, or fluid that hasn’t cleared after three months, your pediatrician may refer you to an ear, nose, and throat specialist to discuss whether ear tubes could help. These tiny tubes are placed in the eardrum during a brief procedure and allow fluid to drain freely, breaking the cycle of repeat infections.
Reducing the Risk
Keeping up with your baby’s recommended vaccines is one of the most effective preventive steps. The pneumococcal vaccine (Prevnar) and the Haemophilus influenzae type B (Hib) vaccine protect against the most common bacteria behind ear infections. Beyond vaccines, minimizing exposure to cigarette smoke, keeping your baby upright during bottle feeds, and breastfeeding when possible all reduce risk. Frequent handwashing during cold season helps too, since ear infections almost always start as viral upper respiratory infections.
