Ear infections are one of the most common reasons parents end up at the GP with a young child, and one of the most misjudged at home. The classic story — a cold that's getting better, then 48 hours later your baby is suddenly more miserable than they were on day one and won't sleep flat — is the picture in roughly half of preschool ear infections. Knowing what to look for and what current UK guidance actually says about antibiotics takes a lot of the guessing out of an unsettled night. Logging temperature, crying patterns, and feeds in Healthbooq gives you something concrete to show the GP rather than relying on memory at 9 a.m. on no sleep.
Why Young Children Get Them
The Eustachian tube — the small channel connecting the middle ear to the back of the throat — is shorter, narrower, and more horizontal in babies and toddlers than it is in older children and adults. Its job is to drain fluid out of the middle ear and equalise pressure. In a cold, the tube swells shut from the same inflammation that's blocking your child's nose, and fluid backs up behind the eardrum. Bacteria from the throat (typically Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis) travel up the blocked tube into the warm fluid and multiply. That's the bacterial superinfection that turns "a cold" into "an ear infection."
This explains two things parents often notice. First, ear infections almost always follow a respiratory virus — the cold isn't separate, it's the trigger. Second, they're heavily concentrated in the under-threes. Eustachian tube anatomy improves with growth; by age five most children have outgrown the worst of it.
Risk factors documented by the AAP and NICE include: nursery attendance, exposure to tobacco smoke, bottle feeding (especially when fed lying flat), and a family history of recurrent ear infections.
Recognising It in a Baby Who Can't Tell You
In a child who can't yet point to where it hurts, look for the pattern, not single signs.
The clearest tell is a sudden second wave. Your child has had a cold for four or five days, the runny nose is settling, and then they get notably worse — fever returns, crying is harder to console, sleep falls apart. That second peak is classic acute otitis media.
The next strongest sign is positional: inconsolable crying that's worst when lying flat. Lying down increases pressure behind the inflamed eardrum and makes the pain spike. A baby who screams every time you put them down at bedtime but settles when held upright on your shoulder is telling you something.
Other signs:
Increased night waking, particularly waking with a sharp cry.
Pulling, batting, or rubbing at the ear. On its own this is not specific — teething and habit do the same — but combined with the rest of the picture it's meaningful.
Fever (over 38°C). Often present, but not always.
Reduced feeding, especially breast or bottle, where sucking and swallowing changes pressure in the middle ear and hurts more.
Discharge from the ear — yellow or pus-like fluid leaking from the ear canal. This usually means the eardrum has perforated, which sounds alarming but actually relieves the pressure and the pain. Perforations almost always heal on their own within a couple of weeks.
Balance issues, falling more than usual, or unusual head tilting in an older toddler.
What Happens at the GP
There's no reliable way to diagnose an ear infection from the outside. The GP looks into the ear canal with an otoscope. A normal eardrum is pearly grey, slightly translucent, with a clear cone-shaped light reflex. An acutely infected one is red, bulging, and the light reflex is lost. Sometimes pneumatic otoscopy (a quick puff of air to check eardrum movement) is used.
If you suspect an ear infection, see the GP. Don't wait it out at home guessing.
Treatment: When to Watch and When to Treat
NICE guidance recommends a tiered approach.
For most children over two with mild to moderate symptoms, watchful waiting for 72 hours is appropriate. Roughly two-thirds of ear infections resolve without antibiotics in that window. The GP may give a "delayed prescription" — a script you fill only if your child isn't improving at 72 hours. This is mainstream UK practice, not undertreatment, and it's part of why UK antibiotic resistance rates are lower than in countries where antibiotics are reflexive.
Antibiotics are recommended from the start for: children under two; severe ear pain regardless of age; high fever (above 39°C); systemically unwell children; bilateral infection in under-twos; ear discharge; children who haven't improved after 72 hours of watchful waiting.
Amoxicillin is the UK first-line antibiotic, typically a 5 to 7 day course at age-appropriate dose. For penicillin allergy, clarithromycin or erythromycin. Finish the full course; not finishing is a real driver of recurrence and resistance.
Pain relief, throughout. Paracetamol or ibuprofen at the correct dose for weight, given regularly for the first 48 hours rather than waiting for distress to peak, makes a meaningful difference. The NHS dose chart is the source — never adult-dose-by-eye for a small child. Warm flannel against the ear can help. Don't put cotton buds, oils, or warmed onion (yes, this is a thing parents try) into the ear canal.
What Doesn't Help
Decongestants and antihistamines don't shorten ear infections in children and aren't recommended.
Eardrops aren't useful for routine acute otitis media without a perforation — the eardrum is intact, so drops don't reach the infection.
Antibiotics for every ear infection isn't supported by current evidence, and it drives antibiotic resistance and side effects (diarrhoea, thrush, rash) without much benefit for the milder cases.
Recurrent Infections and Glue Ear
Three or more ear infections in six months, or four or more in a year, is the threshold at which NICE suggests considering ENT referral. Persistent middle ear fluid (glue ear, or otitis media with effusion) — the fluid that lingers after the acute infection settles — can affect hearing for weeks to months and sometimes affects speech development if it persists.
ENT options include grommets (small drainage tubes inserted through the eardrum under general anaesthetic, which equalise pressure and prevent further fluid build-up) and adenoidectomy. Grommets typically stay in 6 to 18 months and fall out on their own. They're considered when ear infections are frequent, when glue ear is causing measurable hearing loss, or when speech or learning is being affected.
When to Get Urgent Help
Call 111 or see a GP urgently for: a baby under three months with fever; a child who is very unwell, drowsy, or unresponsive; severe headache, neck stiffness, or rash that doesn't blanch.
Call 999 or go to A&E for: signs of meningitis (stiff neck, photophobia, non-blanching rash, drowsiness); facial weakness or asymmetry on the same side as the infected ear; sudden severe swelling or redness behind the ear (mastoiditis — uncommon but serious); a child who is severely unwell or won't wake properly.
Key Takeaways
Acute otitis media is one of the most common bacterial infections in children under three, and most often follows a cold that seemed to be improving. In babies who can't say their ear hurts, the tell is often inconsolable crying when laid flat plus a sudden second wave of unwellness on top of a winding-down viral illness. NICE guidance supports 72 hours of watchful waiting in most children over two; under two, severe pain, high fever, or no improvement at 72 hours warrant amoxicillin.
