Why is my child getting sick so often after starting childcare (and is it normal)?

If your child has started childcare and suddenly seems to have a permanent runny nose, you are not imagining it. Many children get sick more often in the first months of childcare. Sometimes it feels like they recover from one thing just in time to collect the next thing from the communal germ buffet. Delightful. While it can feel exhausting, it’s also very common.

Young children are still building their immune systems. When they start childcare, they’re spending time with other children, shared toys, group routines and all the everyday germs that come with early childhood. Most childcare illnesses are mild and pass with rest, fluids and time. But it’s still important to know what’s common, when to keep your child home, and when to seek medical advice.

Why do children get sick more often in childcare?

Childcare brings children into close contact with each other.

They’re playing together, sharing spaces, touching toys, exploring with their hands, and sometimes putting things in their mouths that absolutely did not need that level of investigation.

At the same time, young children are still developing their immune systems. Before starting childcare, they may not have been exposed to many common childhood viruses.

So when childcare begins, their immune system gets introduced to a much wider world of germs.

This doesn’t mean your childcare service is doing something wrong. Infections are common in young children and in early childhood education and care settings. The National Health and Medical Research Council’s Staying Healthy guidelines are used by services to help limit the spread of infectious diseases in these environments.

What are the most common childcare illnesses?

Every child is different, but there are a few illnesses that tend to make regular appearances in childcare settings.

Colds

Colds are one of the most common childhood illnesses.

Symptoms can include:

runny or blocked nose
sneezing
mild cough
sore throat
low-grade fever
tiredness or grumpiness

It’s not unusual for children to have several colds, especially when they’re new to group care. Raising Children Network notes children should see a GP if they won’t drink fluids, vomit frequently, are unusually tired or sleepy, have a fever that doesn’t improve after 48 hours, have noisy breathing or breathing difficulty, or if you’re worried.

Gastro

Gastroenteritis, often just called gastro, can move quickly through childcare settings.

Symptoms may include:

vomiting
diarrhoea
stomach pain
tiredness
loss of appetite

The main concern with gastro is dehydration, especially in babies and young children. Offer fluids and follow your service’s illness policy about when your child can return.

Healthdirect notes that keeping children home from school or day care can help stop the spread of illness, and recommends seeing a doctor if symptoms don’t improve after two days.

Hand, foot and mouth disease

Hand, foot and mouth disease is a common viral illness in young children.

Despite the name, it is not usually as dramatic as it sounds.

Symptoms can include:

mild fever
small blisters on the hands, feet or around the mouth
mouth ulcers
reduced appetite
sore throat

Raising Children Network says symptoms often appear 4–6 days after infection, and a mild fever may occur before mouth ulcers or blisters appear.

If your child has hand, foot and mouth disease, check your service’s illness policy and seek medical advice if they seem very unwell, are not drinking, or you’re concerned.

Other illnesses you may hear about

Childcare services may also see cases of:

conjunctivitis
ear infections
viral rashes
influenza
COVID-19
chickenpox
head lice

Some illnesses require children to stay home for a set period or until certain symptoms have cleared. Healthdirect provides guidance on exclusion periods for many infectious conditions, though services may also have their own policies.

How often do children get sick in childcare?

This is the question many parents quietly ask after the third runny nose in a month.

In the first year of childcare, frequent mild illness can be very normal.

You might notice:

colds every few weeks
symptoms that seem to overlap
coughs or runny noses that linger
more sick days than expected

It can feel like a lot, especially when you’re juggling work, family life and the emotional logistics of calling in sick again.

For many families, this stage becomes easier over time as children’s immune systems develop and routines settle.

What’s usually normal?

Most common childcare illnesses are mild.

It’s usually normal for children to:

have several colds in the first year of childcare
seem tired or clingy when unwell
need a few days at home to recover
have appetite changes during illness
take time to fully bounce back

A pattern of “sick, recover, back to childcare, repeat” can feel relentless, but it’s often part of the early childcare phase.

Not glamorous. Very normal.

When should I keep my child home from childcare?

Your childcare service will have an illness policy that explains when children need to stay home.

In general, children should stay home if they:

are too unwell to join normal activities
have vomiting or diarrhoea
have a fever or are generally unwell
need one-on-one care because of illness
have symptoms listed in the service’s exclusion policy

Exclusion rules help protect other children, educators, families and vulnerable people in the community. Healthdirect explains that children with infectious illnesses may need to stay home from day care or school to reduce spread.

If you’re unsure, call your childcare service and ask what they need you to do.

When should I see a doctor?

Most mild illnesses can be managed with rest, fluids and care at home.

But it’s important to seek medical advice if your child:

has a high or persistent fever
is under 3 months old with a fever
has difficulty breathing, noisy breathing or wheezing
is unusually drowsy or hard to wake
is not drinking fluids
has fewer wet nappies or signs of dehydration
has vomiting or diarrhoea that isn’t improving
has symptoms that are getting worse instead of better
has a rash that worries you
just doesn’t seem right to you

The NHMRC notes that a fever over 38°C in a child under 3 months should be checked by a doctor. Raising Children Network advises calling 000 for serious signs such as severe drowsiness or unresponsiveness, difficulty breathing, blue skin, seizures, or a rash that doesn’t fade when pressed.

And truly, trust your instincts. If you’re worried, it’s always okay to seek advice.

The bigger picture

If it feels like your child is always sick after starting childcare, you’re very much not alone.

This phase can be frustrating, disruptive and tiring. It can mean missed work, cancelled plans and more laundry than anyone should reasonably be expected to manage.

But for many children, frequent mild illness becomes less intense over time.

As your child grows, their immune system learns, routines settle, and you get better at knowing what’s normal for them.

Not easy. But common.

It’s common for children to get sick more often when they first start childcare. Colds, gastro and hand, foot and mouth disease are all common in early childhood settings. Most mild illnesses pass with rest, fluids and time, but children may need to stay home to recover and prevent spreading illness. Always follow your service’s illness policy, and seek medical advice if symptoms are severe, worsening or something doesn’t feel right.
