If you’ve ever found yourself Googling your child’s symptoms at 2 am, you’re far from alone. From runny noses and unexplained fevers to itchy rashes and tummy bugs, child health issues are a near-constant feature of family life, especially when little ones are at daycare, kindy, or school.
Most are mild and pass on their own. But knowing what’s normal, what to do at home, and when children’s healthcare needs to step in can take a lot of the stress out of those middle-of-the-night moments.
This guide walks through the common childhood illnesses Australian parents ask about most, and what to expect at each stage.
Why Kids Get Sick So Often
Young children’s immune systems are still learning. Every germ they meet is a new one, which is why a child in daycare can pick up around six to eight colds a year, according to HealthDirect, far more than the average adult.
Add in close-contact play, shared toys, and the fact that toddlers are not great at covering their coughs, and it’s easy to see why illness spreads so quickly through families and classrooms. The good news: most of these infections build long-term immunity over time.
The Most Common Reasons Parents Bring Their Child To A Doctor
Here are the conditions that bring children into our child health clinic most often, along with what to look out for.
Fevers
A fever is one of the most common signs your child’s body is fighting off an infection. Most fevers are caused by viruses and resolve within a few days. According to HealthDirect, a fever in itself is not usually dangerous, but it can be a sign that something more serious is going on, especially in babies.
See a child doctor if: your child is under three months old and has any fever, the fever lasts more than 48 hours, or your child seems unusually drowsy, will not drink fluids, or has a rash that does not fade when pressed.
Coughs And Colds
Most coughs and colds in children are caused by viruses, which means antibiotics will not help. Symptoms usually clear up within a week to ten days. Plenty of fluids, rest, and saline nasal drops for younger children can help with comfort.
See a doctor if: your child has trouble breathing, the cough lasts more than two weeks, or they develop a high fever alongside the cough.
Ear Infections (Otitis Media)
Ear infections are extremely common in children under five, often following a cold. Signs include ear pain, tugging at the ear, irritability, trouble sleeping, and sometimes fluid leaking from the ear.
While many ear infections clear up on their own, some need treatment to prevent complications. If your child seems to be in significant pain or symptoms last more than a couple of days, it’s worth booking an appointment.
Gastro (Vomiting And Diarrhoea)
Gastroenteritis spreads quickly through families and childcare centres. The biggest risk for young children is not the illness itself, but dehydration. Offer small, frequent sips of water or oral rehydration solution rather than large drinks at once.
See a doctor urgently if: your child has fewer wet nappies than usual, dry lips, sunken eyes, no tears when crying, or unusual sleepiness.
Childhood Rashes
Rashes can be alarming for parents, but most are caused by mild viral infections (like roseola or hand, foot and mouth) or skin conditions like eczema. Eczema often flares up with weather changes and can usually be managed with regular moisturising and, when needed, prescribed creams.
See a doctor urgently if: the rash looks like small purple or red spots that don’t fade when you press on them — this can be a sign of meningococcal disease and needs immediate attention.
Asthma Symptoms
If your child has a persistent cough at night, wheezes when running around, or gets short of breath easily, they may have asthma. Around one in ten Australian children have asthma, and early diagnosis means it can be well managed with an action plan and the right medication.
Childhood Allergies
Hay fever, food allergies, and eczema often run together. Mild allergic reactions usually involve a rash, itching, or sneezing. Severe reactions (anaphylaxis), or including difficulty breathing or swelling of the tongue or throat, are a medical emergency and need an ambulance straight away.
If you suspect your child has an allergy, your GP can help with diagnosis, an action plan, and referrals if needed.
Prevention: Simple Habits That Support Children’s Healthcare
Prevention will not stop every bug, but it makes a real difference. Here are some prevention practices you can instil with your children at home.
- Stick to the routine immunisation schedule Australia uses. Your GP can also help with catch-ups if you’ve missed any
- Teach handwashing before meals and after using the toilet
- Keep sick children home from school or daycare to slow the spread
- Make sure your child eats well, sleeps enough, and stays active
When To Book Your Children’s GP / Family Doctor
It’s always okay to bring your child in if you’re unsure; that’s what we’re here for. As a general guide, book an appointment if:
- Your child’s symptoms aren’t improving after two to three days
- Your child seems unusually drowsy, floppy, or hard to rouse
- They’re not drinking fluids or having fewer wet nappies
- Breathing seems fast, noisy, or laboured
- You’re simply worried — parents know their child best
For severe symptoms, difficulty breathing, a non-fading rash, seizures, or persistent vomiting, call 000 or go to your nearest emergency department.

Frequently Asked Questions
How often is it normal for a child to get sick?
It’s completely normal for young children to get six to eight colds a year, and even more if they’re at daycare. As their immune system matures, the frequency typically decreases.
When should I take my child to a doctor versus the emergency department?
Book a GP appointment for symptoms that are mild but concerning, not improving, or lasting more than a couple of days. Go straight to the emergency (or call 000) for difficulty breathing, severe drowsiness, seizures, a non-fading rash, or any sudden serious change.
Can I give my child paracetamol or ibuprofen for a fever?
Both can help with comfort and pain when used according to the dosing instructions on the pack. Never give aspirin to children. If your child has asthma or a chronic condition, check with your GP or pharmacist before giving ibuprofen.
Are antibiotics needed for most childhood illnesses?
No. Most common childhood illnesses are viral, which means antibiotics will not help. Your GP will recommend antibiotics only when there’s a clear bacterial cause that needs them.
How do I know if my child is dehydrated?
Watch for fewer wet nappies, dry lips, sunken eyes, no tears when crying, and unusual sleepiness. If you see these signs, see a doctor urgently or go to your nearest emergency department.
