The most reliable signs that your child has an ear infection are persistent fussiness, trouble sleeping, fever above 100.4°F, and tugging or pulling at one or both ears. Since most ear infections strike before children can talk, parents typically have to piece together behavioral clues rather than rely on a verbal complaint. Knowing what to look for, and what else might be causing the fussiness, can save you a lot of guesswork.
Signs to Watch For
Ear infections cause pressure and pain inside the middle ear, and young children show that discomfort in predictable ways. The National Institute on Deafness and Other Communication Disorders lists these key signs:
- Tugging or pulling at the ear. This is the classic signal, though on its own it doesn’t confirm an infection (more on that below).
- Fussiness and crying that seems out of proportion or harder to soothe than usual.
- Trouble sleeping. Lying flat increases pressure in the middle ear, so many kids with infections wake more often or resist being put down.
- Fever, especially in infants and younger children.
- Fluid draining from the ear, which can look yellowish or whitish.
- Balance problems or clumsiness, since the middle ear plays a role in balance.
- Trouble hearing or responding to quiet sounds.
You don’t need to see every one of these. A child who has a cold, then suddenly becomes much fussier and starts sleeping poorly, is a very common ear infection pattern. The infection often develops a few days into an upper respiratory illness because swelling blocks the small tube that drains fluid from the middle ear.
Teething or Ear Infection?
This is one of the trickiest distinctions for parents, because teething and ear infections share several symptoms: ear pulling, irritability, and mild fever. A few differences help sort them out.
Teething tends to cause swollen or tender gums, increased drooling, and a strong urge to chew on objects. It may raise your child’s temperature slightly, but it doesn’t typically cause a true fever above 100.4°F. Ear infections, on the other hand, often push fevers higher, cause more intense and persistent crying, and get noticeably worse when the child lies down. If your baby is pulling at their ear but also gnawing on everything in sight with visibly puffy gums and no real fever, teething is the more likely explanation.
The combination of clues matters most. Frequent or intense ear pulling paired with fever, loss of appetite, or fluid from the ear points toward infection rather than a new tooth coming in.
Subtle Hearing Changes
Fluid buildup in the middle ear, whether from an active infection or leftover fluid after one, can temporarily muffle your child’s hearing. In babies, this may look like not turning toward your voice or not startling at loud sounds the way they usually do. In toddlers, you might notice they stop responding to quiet sounds, turn the TV volume up, or seem to ignore you when you speak from across the room.
These hearing changes are almost always temporary and resolve once the fluid drains. But if your child has repeated ear infections or fluid that lingers for weeks, it’s worth paying attention to speech development. Persistent fluid during the ages when children are learning language can slow things down if it isn’t addressed.
What Happens at the Doctor’s Office
A doctor diagnoses an ear infection by looking at the eardrum with a small lighted scope. A healthy eardrum is translucent and moves freely. An infected one looks red, swollen, and bulges outward because of the pressure from trapped fluid behind it. In some cases the doctor will use a small puff of air to check whether the eardrum moves normally. Limited movement is a strong sign of fluid buildup and is 70% to 90% accurate for confirming middle ear fluid.
There’s an important distinction your doctor may mention. An active infection (acute otitis media) involves fluid plus inflammation, pain, and often fever. Fluid without active infection symptoms (otitis media with effusion) is common after an infection resolves. The fluid-only version doesn’t usually need treatment and clears on its own, though it can temporarily affect hearing.
Not Every Infection Needs Antibiotics
This surprises many parents, but current pediatric guidelines distinguish between cases that need immediate antibiotics and cases where it’s safe to wait and watch for a couple of days.
Antibiotics are recommended right away when:
- Your child has moderate or severe ear pain, pain lasting 48 hours or more, or a fever of 102.2°F or higher.
- Both ears are infected in a child between 6 and 23 months old, even if symptoms are mild.
A “watch and wait” approach is considered safe when:
- Only one ear is infected in a child 6 to 23 months old, with mild symptoms and a fever below 102.2°F.
- Your child is 2 years or older with mild symptoms in one or both ears.
Watch-and-wait means the doctor gives you a plan to manage pain at home and asks you to return or fill a prescription if symptoms don’t improve within two to three days. Many mild ear infections clear up on their own in that window. This approach helps avoid unnecessary antibiotics, which reduces the risk of side effects and antibiotic resistance.
Signs That Need Prompt Attention
Most ear infections, while painful, aren’t emergencies. But certain symptoms call for a faster response. The CDC recommends contacting a healthcare provider if your child has a fever of 102.2°F or higher, pus or fluid draining from the ear, symptoms that are getting worse instead of better, or symptoms that last beyond two to three days. Hearing loss that doesn’t bounce back after the illness resolves also warrants a follow-up visit.
For infants under 3 months old, the threshold is much lower: any fever of 100.4°F or higher needs prompt medical evaluation, regardless of whether you suspect an ear infection or something else.
