Ear Infections in Babies: Signs, Treatment, and When to See a Doctor

Ear infections (otitis media) are extremely common in babies and young children — roughly three-quarters of children will have at least one by age 3. Here's what you need to know.

Why babies are prone to ear infections

The Eustachian tube — the canal connecting the middle ear to the back of the throat — is shorter, wider, and more horizontal in babies than in adults. This makes it much easier for bacteria or viruses from a cold or throat infection to travel up into the middle ear.

Other contributing factors:

• Immature immune systems
• Group childcare (exposure to more viruses)
• Passive smoke exposure (significantly increases risk)
• Bottle feeding lying flat (formula can pool near the Eustachian tube opening)

Types of ear infection

Acute otitis media (AOM): Middle ear infection — bacterial or viral infection behind the eardrum. Most common type.

Otitis media with effusion ("glue ear"): Fluid in the middle ear without active infection. Often follows AOM. Can persist for weeks to months and causes temporary hearing reduction. Very common — many children have episodes, most resolve without treatment.

Outer ear infection (otitis externa): Infection of the ear canal (not the middle ear). Less common in babies; associated with swimming.

Signs of an ear infection in babies

Babies can't tell you their ear hurts, which makes diagnosis harder. Watch for:

• Unusual crying or irritability, particularly after a cold
• Pulling, tugging, or rubbing the ear — though this is a non-specific sign and can be teething or simply discovery of the ear
• Disturbed sleep — ear pain is worse when lying flat (increased pressure)
• Fever — not always present
• Discharge from the ear — if the eardrum has perforated (which relieves pain), you may see yellow or clear fluid; this is an indication of infection
• Reduced response to sounds — hard to assess in babies, but worth noting
• Poor feeding — swallowing can be uncomfortable with a middle ear infection

What happens at a GP appointment

The GP will examine both ears with an otoscope (a small light) to look at the eardrum. Signs of AOM include a red, bulging eardrum and sometimes fluid behind it.

Treatment: the UK approach

UK guidance (NICE): Most ear infections in children (over 6 months) are viral — or bacterial but self-limiting — and do not require immediate antibiotics.

For most children:

• Pain relief first: Paracetamol or ibuprofen for comfort
• Watchful waiting for 72 hours: Most infections resolve within 3 days
• A delayed prescription may be issued — a prescription you fill only if symptoms haven't improved after 2–3 days

Antibiotics are recommended immediately if:

• Baby is under 6 months
• Symptoms are severe (high fever, very unwell, intense pain)
• There is discharge from the ear (perforated eardrum)
• Symptoms are not improving after 3 days
• Baby has a weakened immune system or other complicating condition

Antibiotic of choice: Amoxicillin (if not allergic to penicillin). 5-day course in the UK.

Managing pain at home

• Paracetamol or ibuprofen — adequate analgesia is the most important thing
• Warm compress over the ear — a warm (not hot) flannel can provide relief
• Upright positioning — reduces pressure in the middle ear; helps during sleep
• Continue feeding normally — sucking and swallowing can be uncomfortable; offer more frequently for shorter periods

Glue ear — what happens next

If fluid persists in the middle ear after an infection (or simply accumulates without clear infection), this is glue ear. It causes:

• Temporary hearing loss — equivalent to wearing earplugs
• Sometimes speech delay in toddlers with persistent glue ear

Most cases resolve on their own within 3 months without treatment.

If glue ear persists and is affecting hearing and speech development, a referral to ENT may be made for consideration of grommets (small tubes inserted into the eardrum to allow drainage). This is a common procedure but usually not considered until the child is 2–3 years and glue ear has been persistent.

Recurrent ear infections

Some children have frequent recurrences (3+ per year). Referral to ENT for assessment and possible grommets may be appropriate.

What helps reduce recurrence:

• Avoid smoke exposure (passive smoking is a strong risk factor)
• Breastfeeding (protective effect on immune system and Eustachian tube function)
• Upright bottle feeding position
• Vaccinations — the pneumococcal and Hib vaccines reduce bacterial ear infection risk
