“He’s Sick Again?!”
If your toddler is falling sick again — with yet another cold or fever — you’re not alone. In Singapore, frequent illness in young children is normal and often part of healthy immune development.
A mother recently shared, “It feels like we’ve been to the clinic every week. He just recovered from a cough, and now he has a runny nose again.” This sentiment is common among parents, especially those with toddlers in childcare. Frequent illnesses in young children can be concerning, but they often indicate a developing immune system rather than a serious health issue.
Why Toddlers Get Sick So Often
In the early years, a child's immune system is still maturing. Unlike adults, toddlers are encountering many viruses and bacteria for the first time. Each exposure helps their immune system learn and adapt.
In Singapore, it's common for toddlers attending childcare to experience 8 to 12 viral infections per year. These include colds, fevers, stomach bugs, and hand, foot and mouth disease (HFMD), a highly contagious condition that spreads easily in group settings.
While frequent viral infections are normal, repeated hospitalisations, prolonged recovery, or failure to thrive may signal something more serious.
“We see many healthy toddlers who get sick monthly — and that’s still considered normal,” explains Dr Jacquelyn Melody, Senior Physician at Oaklife Family Clinic. “As long as they’re growing well and bouncing back between episodes, it’s usually not a red flag.”
What Are These Frequent Toddler Illnesses?
Most illnesses that toddlers catch are viral, not bacterial, and often resolve on their own with rest, hydration, and supportive care. These frequent infections are part of how a child’s immune system builds memory and strength. In Singapore’s warm and humid climate — especially in preschool environments — viruses spread easily through shared toys, poor hand hygiene, and close physical interaction.
Let’s break down some of the most common childhood infections in Singapore:
Colds and Coughs (Rhinovirus, Adenovirus)
These are the most common infections in toddlers. Children can catch a new cold every few weeks, particularly in childcare settings. Typical symptoms include runny or stuffy nose, sore throat, sneezing, and mild cough. Fevers, if present, are usually low-grade. Although mild, these colds can still disrupt feeding and sleep.

Mild Viral Fevers
Fevers are often a response to viral infections and may not indicate anything serious. They commonly occur with colds, flu, or roseola. Parents are often more worried about the thermometer reading than the child's behaviour — but it’s the latter that matters most.

Gastroenteritis (Stomach Flu)
Caused by viruses like rotavirus or norovirus, stomach flu leads to vomiting, diarrhoea, fever, and stomach pain. It spreads quickly in preschools. The main danger in toddlers is dehydration due to fluid loss and poor oral intake.
Hand, Foot and Mouth Disease (HFMD)
According to the Ministry of Health Singapore, over 21,000 HFMD cases were reported in 2023 alone, with spikes typically occurring between March and October. HFMD is highly contagious and affects many young children in Singapore, particularly in group care settings. It presents with fever, painful mouth ulcers, and blisters on hands, feet, or buttocks. Children often eat and drink less, so hydration is key.

RSV and Other Respiratory Viruses
Respiratory Syncytial Virus (RSV) causes flu-like symptoms and, in younger children, may lead to wheezing or bronchiolitis. Watch for rapid breathing or fatigue, especially in children under 2. RSV and influenza often spike during seasonal waves.

Conjunctivitis (Pink Eye)
Conjunctivitis causes red, watery, itchy eyes with possible yellow discharge. It spreads quickly among children and may require eyedrops if bacterial. Proper handwashing can reduce transmission.
When to Worry About Frequent Illness
Although repeated mild infections are usually harmless, certain signs indicate the need for medical attention. If your child is not gaining weight, seems constantly fatigued, or has multiple bacterial infections (like pneumonia or UTIs) in a year, it's best to consult a doctor. Similarly, symptoms that persist beyond a week, or illnesses that leave your child unusually weak, should be checked.
“Most of the time, frequent infections are just part of normal immune training,” says Dr Daniel Lim, Senior Physician at Oaklife. “But if your child isn’t recovering well or something feels off, we’re here to investigate.”
How to Support Your Toddler’s Immunity
As parents, there’s a lot you can do to help reduce the severity and frequency of illnesses — even if you can’t avoid every single virus.
🥦 A balanced diet rich in fresh produce, lean protein, and whole grains provides essential nutrients like zinc, iron, and vitamin C that boost immunity. Avoid overly processed and sugary foods, which can suppress immune function.
💤 Sufficient sleep is crucial. Most toddlers need between 11 to 14 hours of sleep per day, including naps. An overtired child is more prone to infections and takes longer to recover.
💉 Keeping up with vaccinations, including the National Childhood Immunisation Schedule, ensures your child is protected against preventable diseases. In particular, the flu vaccine is recommended yearly from 6 months of age.

🧼 And don’t underestimate basic hygiene habits. Regular handwashing, disinfecting shared items, and teaching kids to cover coughs can go a long way in reducing the spread of viruses — including HFMD.
“You don’t need to raise your child in a bubble,” Dr Jacquelyn Melody adds. “Some viral exposure is actually good. It helps build natural immunity — as long as we support the body with rest, nutrition, and appropriate care.”

What About the Parents?
Let’s not forget the real toll frequent illness takes on caregivers — disrupted sleep, days off work, worry, and burnout. If you’ve been feeling like you’re always cancelling plans, or bouncing from one clinic visit to the next, you’re not alone. This is one of the most common — and temporary — stages in parenting young children.
The good news? By age 5 or 6, most children have built up stronger immunity, and these episodes become far less frequent.
It’s a Phase — and It Will Pass
Frequent illness in toddlers is more common than you think — and in most cases, it’s not a sign of poor health but a phase of growth. Your child’s immune system is learning with every bug they beat. With good habits, vaccines, and your loving care, they will emerge stronger and more resilient.

Frequently Asked Questions (FAQs)
Q. Is it normal for my toddler to fall sick every month?
A. Yes, it can be normal — especially if your child attends preschool. In Singapore, toddlers commonly catch 8 to 12 viral infections per year. These are mostly mild, self-limiting illnesses like colds, flu, or HFMD that help build long-term immunity.
Q. Does frequent illness mean my child has a weak immune system?
A. Not necessarily. A developing immune system is supposed to learn by encountering new viruses. If your child recovers well, grows steadily, and has no serious infections, this is likely part of normal immune development.
Q. When should I worry about frequent infections?
A. Speak to your doctor if your child is not gaining weight, has repeated bacterial infections (e.g. pneumonia or UTIs), shows constant fatigue, or has persistent fever or symptoms lasting more than 7 days. These may require further evaluation.
Q. What can I do to reduce how often my toddler gets sick?
A. Ensure your child has a balanced diet, gets adequate sleep (11–14 hours daily), stays up to date with vaccinations, and practises good hand hygiene.
Q. How do I know if it’s time to visit a doctor?A. Visit a clinic if your child has high fever lasting more than 3 days, is not drinking well, seems lethargic, or is not their usual self. Trust your instincts — if something feels off, it’s worth having them checked.
