Ear Infection Symptoms You Should Never Ignore

Ear infections are very common in young children. In fact, about 50 percent of all children will have at least one ear infection by their first birthday. As a mum of three boys, I’ve dealt with my fair share of ear infections. My middle son needed grommets (more on what those are later). But, my experience isn’t just limited to my boys. As a paediatrician in a large city paediatrics practice, I frequently see children with ear infections and their parents always have lots of questions: What causes ear infections? Why do kids get them more frequently than adults? Do all ear infections need to be treated? You may have the same questions, too. So here it is: The guide to absolutely everything you need to know about ear infections.

What exactly is an ear infection?

Ear infections, known by the medical term otitis media, are an infection of the middle ear — specifically the space behind the ear drum. It is not uncommon for children to have ear infections following colds or other viral illnesses, because the fluid that builds up behind the inner ear during those illnesses can get infected. Environmental allergies can also cause a buildup of fluid behind the ear drum, and lead to an infection.

What are the symptoms of an ear infection?

If your child is a baby or toddler, you may notice that she tugs at her ears. That symptom alone could mean that she’s teething or practicing a self-soothing behaviour. However, if she’s having these additional symptoms — or you’re concerned — you should always consult your doctor right away:

  • Ear pain
  • Fever
  • Vomiting
  • Poor appetite
  • Difficulty sleeping
  • General crankiness

How are ear infections diagnosed?

The only way to diagnose an ear infection is to have your child’s doctor look in his ears to see if the typical signs of an ear infection, like redness or pus behind the ear drum, are present.

Why do kids get ear infections more frequently than adults?

Children are more likely to have viral illnesses than adults because they are in close contact with other children and young children often put toys and other objects in their mouths. These illnesses cause swelling of the mucus membranes in the nose and throat, which make it more likely for bacteria to build up in the nose. In addition, children’s eEustachian tubes are more narrow and more horizontal then adults. This narrow tube runs from the back of the ear into the throat and allows for fluid drainage from the ear. As children get older, the Eustachian tube lies more on a diagonal which helps to promote fluid drainage. Since children’s Eustachian tubes are more horizontal, they tend to clog easier and do not drain fluid as well making children more susceptible to ear infections.

How are ear infections treated?

First and foremost, you want to make sure your child is comfortable by controlling her pain. If she’s older than six months, you can manage her pain with over-the-counter pain relievers such as paracetamol and ibuprofen. ( It is not recommended to use cough or cold medications or decongestant in children.) Your doctor will then decide how to treat the actual ear infection based on your child’s age, history of previous infections, degree of illness and underlying medical problems. One strategy is to prescribe antibiotics and the second is watchful waiting. Watchful waiting refers to the idea of observing a child for 48 to 72 hours before starting antibiotics. If the child isn’t feeling better within that timeframe then she would start taking antibiotics.

However, there are some cases in which watchful waiting is not appropriate and antibiotics should always be given:

  • Children are younger than age 2
  • Older children who have had ear pain for more than 48 hours
  • Those with a temperature above 39°C
  • Children with an infection in both ears
  • There is drainage from the ear
  • The child looks unwell to a physician
  • Children who have compromised immune systems

What are grommets and when might a child need them?

Grommets (aka ear tubes) are tiny tubes that a doctor puts in a child’s ear drums to create an opening. This procedure is done surgically by an Ear, Nose and Throat specialist. Children may need grommets if they are having repeated ear infections (typically more than three infections in a six month period), or have chronic fluid buildup behind the ears (the later can lead to hearing loss and speech delays). If you think that your child may need ear tubes, reach out to your doctor.
