If your baby has been extra fussy or waking up screaming at night, you might be asking yourself how to tell if infant has an ear infection. Infants cannot tell us what hurts, so we have to watch for a pattern of clues instead of one single sign. Many parents feel that same worry after their little one has had a cold. The good news is that knowing what to look for helps you decide when it is time to get help.

Why Infants Get Ear Infections So Often
Babies get ear infections more than older kids or adults because of how their ears are built. Their Eustachian tubes are shorter, wider, and more horizontal. This shape makes it easy for fluid to get trapped instead of draining away. When fluid sits there, bacteria can grow fast and cause infection.
The Cold-to-Ear-Infection Pipeline
Most ear infections start right after a viral cold or upper respiratory infection. The congestion from the cold swells the lining of the Eustachian tube and blocks drainage. That is why you often see ear trouble a few days after the runny nose and cough begin.
If your baby still has a stuffy nose, our guide on saline nasal drops for newborns shows safe ways to help clear things out and may lower the chance of fluid backing up.
The Most Reliable Signs of an Infant Ear Infection
You rarely see just one symptom. Instead, look for a cluster of changes that appear after a recent cold or runny nose. These signs together paint a clearer picture than any single behavior.
Sudden Fussiness or Night Waking (Especially Lying Flat)
One of the biggest clues is sudden crying or waking when you lay your baby down. When your infant is upright in your arms, gravity helps keep pressure off the middle ear. The moment you place them flat in the crib, fluid presses harder on the eardrum and pain spikes. Many parents notice their baby sleeps fine being held but screams the second their head hits the mattress.
Changes in Feeding and Appetite
Sucking and swallowing create pressure changes inside the ear. A baby with an ear infection often pulls away from the breast or bottle after only a few gulps, turns their head, or cries during feeds. You may also notice they seem less hungry overall because eating has become uncomfortable.
Fever (And the “No Fever” Exception)
A fever of 100.4°F (38°C) or higher is common with ear infections. Still, experts note that roughly one in three babies with an ear infection never runs a fever at all. So do not rule it out just because your infant feels cool to the touch. Watch the full pattern of behavior instead.
Fluid Draining From the Ear (Otorrhea)
Yellow, white, or blood-tinged fluid coming from the ear canal is the clearest at-home sign. This usually means the eardrum has ruptured, which actually relieves some pressure and pain. Even though the pain may ease, you still need to call the pediatrician the same day. The rupture needs proper care and follow-up.
The “Ear-Pulling” Myth: Is It Teething or an Infection?
Many parents assume ear pulling always means infection. Studies show this is not true. Happy, well-feeding babies who tug or rub their ears are often just teething or self-soothing. Ear pulling alone does not confirm an ear infection.
How to Tell the Difference
Use this quick comparison to sort it out:
- Teething usually brings lots of drooling, chewing on fists or toys, and swollen gums. The baby still eats well and sleeps normally once soothed.
- Ear infection often follows a cold, includes fever in many cases, and makes feeding painful. The baby may refuse the bottle or breast and wake crying when laid flat.
- Other causes like strep throat are rare in young infants but can also make swallowing hurt. If feeding refusal continues without cold symptoms or fever, mention it to your doctor.
When to Call the Pediatrician
Trust your gut. If something feels off, pick up the phone. You know your baby best.
Red Flag Symptoms for Immediate Care
Call right away if you see any of these:
- Fever in any infant under 6 months old
- Fever over 102.2°F (39°C) at any age
- Fluid, pus, or blood draining from the ear
- Swelling, redness, or tenderness behind the ear (possible sign of mastoiditis)
- Symptoms that last more than 2–3 days or keep getting worse
- Baby is very sleepy, hard to wake, or seems in severe pain

How Pediatricians Diagnose and Treat Ear Infections
A visit to the doctor brings answers fast. Here is what usually happens so you know what to expect.
The Otoscope Exam
The pediatrician uses a lighted tool called an otoscope to look inside the ear. They check for a bulging, red, or cloudy eardrum that does not move well when air is puffed gently against it. This exam is the only way to officially diagnose acute otitis media.
The “Watchful Waiting” Approach
For many older infants with mild cases, the American Academy of Pediatrics supports watching and waiting 48–72 hours while managing pain. Plenty of infections clear on their own during this time. Your doctor will give clear instructions on what to watch for and when to return or start medicine.
Antibiotics vs. Pain Management
Antibiotics (often amoxicillin) are started right away for babies under 6 months, severe pain in both ears, or high fever. For milder cases in older infants, pain relief with infant acetaminophen or ibuprofen is the main treatment at first. Always use the exact dose your doctor or the package recommends for your baby’s weight and age.
Important Note:
Please always consult your pediatrician before giving any medication to your infant. Every baby is different, and the right dose and medicine depend on your child’s age, weight, and overall health. Never start or change medicines based only on general information — your doctor knows your baby best and can guide you safely.
Can Infant Ear Infections Be Prevented?
You cannot prevent every ear infection, but these steps lower the risk:
- Keep your baby upright during bottle feeds so milk does not pool near the Eustachian tubes.
- Avoid secondhand smoke, which irritates the airways and raises infection chances.
- Breastfeed when possible — it passes helpful antibodies to your baby.
- Limit pacifier use after 6 months, since heavy use can affect ear drainage.
Key Takeaways
- Ear pulling by itself is usually teething or comfort, not infection.
- Look for a cluster of signs after a cold: night waking when laid flat, feeding refusal, and possible fever.
- Fluid draining from the ear needs same-day medical attention.
- Only an otoscope exam gives a definite diagnosis.
- Many mild cases improve with watchful waiting and pain relief alone.
Frequently Asked Questions (FAQs)
Can a baby have an ear infection without a fever?
Yes. Up to 30% of infants with ear infections never develop a fever. The other behavioral signs matter just as much.
How long does an infant ear infection last?
Most babies feel better within 48–72 hours once treatment or watchful waiting begins. Fluid can stay behind the eardrum for weeks afterward without causing pain or needing more medicine.
Are ear infections contagious?
The ear infection itself is not contagious. The cold virus that led to it spreads easily from person to person, though.
How can I soothe my baby’s ear pain at night?
Try these steps while waiting for the doctor or medicine to work:
- Keep your baby’s head slightly raised with a rolled towel under the crib mattress (never use pillows in the crib).
- Give the correct dose of infant pain reliever your pediatrician recommends.
- Place a warm (not hot) damp cloth against the outer ear for a few minutes.
- Offer extra cuddles and upright rocking if lying flat hurts.
You are doing the right thing by paying close attention to your baby’s cues. Most ear infections clear well with the right care, and catching them early keeps everyone more comfortable. If you are unsure, a quick call to your pediatrician brings peace of mind every time.
