Children, especially those under five, seem to catch one illness after another — and for good reason: their immune systems are still building a memory of the germs around them. Most childhood illnesses are mild and resolve on their own, but knowing what to expect, and what warning signs matter, helps parents respond calmly and appropriately.
The Common Cold
By far the most frequent childhood illness, a common cold typically brings a runny or blocked nose, mild cough, and sometimes a low-grade fever, lasting seven to ten days. Rest, fluids, and saline nasal drops for younger children are usually all that is needed. See a paediatrician if symptoms last beyond two weeks, if fever is high or persistent, or if your child develops ear pain or difficulty breathing.
Ear Infections
Common in younger children due to the shape of their ear canals, ear infections often follow a cold and present as ear pain, tugging at the ear, irritability, and sometimes fever. While many resolve on their own, a paediatrician should evaluate persistent ear pain, especially in infants who cannot describe their symptoms, as some infections require treatment to prevent complications.
Chickenpox
Marked by an itchy, blistering rash that appears in waves over several days, along with mild fever and fatigue. Chickenpox is highly contagious until all blisters have crusted over. Keep your child home from school during this period, manage itching with lukewarm baths and your paediatrician’s recommended treatments, and seek care if the rash becomes infected (increasing redness, warmth, or pus) or fever is high.
Hand, Foot, and Mouth Disease
Common in toddlers and young children, this viral illness causes small blisters or sores in the mouth and on the hands and feet, often with fever. It is highly contagious in daycare and school settings. Most cases resolve within seven to ten days with supportive care — soft foods, fluids, and fever management. Seek care if your child refuses all fluids, as mouth sores can make drinking painful and lead to dehydration.
Gastroenteritis (Stomach Flu)
Vomiting and diarrhoea, often with mild fever, are usually caused by a viral infection and resolve within a few days. The primary concern is dehydration, especially in younger children. Offer small, frequent sips of fluids or oral rehydration solution. See a doctor urgently if your child shows signs of dehydration — a dry mouth, no tears when crying, noticeably fewer wet nappies, or unusual drowsiness.
Warning Signs That Always Warrant a Doctor Visit
- Fever in an infant under three months old, of any degree.
- Fever above 39°C (102°F) in a child of any age, especially if it persists beyond two to three days.
- Difficulty breathing, unusual drowsiness, or refusal to wake fully.
- Signs of dehydration — dry mouth, sunken eyes, no wet nappies for 8+ hours.
- A rash that does not fade when pressed with a glass.
- Persistent vomiting that prevents any fluids from staying down.
- Any illness that simply feels “different” or more severe than usual — parental instinct is often right.
Vaccination Remains the Best Prevention
Many serious childhood illnesses that were once common are now rare precisely because of routine vaccination. Keeping your child’s vaccination schedule up to date remains one of the single most effective things a parent can do to protect their child’s health.
