Why Would a Child Get Sick at Daycare?

Most reputable daycares around the world adhere to strict health policies. For example, we don’t allow kids in with severe colds, pinkeye, other infectious diseases, etc. So, why would a child get sick at all?

Let’s take a look at some likely reasons.

Immature Immune System

A toddler’s immune system is still developing, making them more susceptible to illnesses. Their bodies are learning to fight off unfamiliar invaders, which can sometimes result in sickness. So, whether they go to daycare or not, new germs from anywhere can get them sick.

Close Contact with Other Kids

An excellent quality of a good daycare is that it helps socialize kids. How? By providing a safe space where they can interact closely with each other, share toys, play together, and explore the world.

All of the wonderful things in daycare are essential for a happy life, but they also increase the likelihood of germ transmission. C’est la vie! This is particularly an issue for children who have not been exposed to many germs before.

Suboptimal Environment at Daycare or Home

Let’s face it: toddlers put their hands and feet into their mouths all the time. So, any environment they spend a lot of time in should be clean and ventilated. Not that our own Clever Daycare is dirty! We’re spotless clean with great HVAC systems. (Check out our amenities.) This is just a list of reasons why an illness might occur.

Cleanliness at home is also crucial. Second-hand smoke, if present, will also stress a toddler’s immune system and make them more vulnerable to illnesses. More on common stressors later in this piece.

We offer daycare programs in Calgary for different age groups, including:

How to Boost a Toddler’s Immune System for Daycare

As a parent, you play a pivotal role in strengthening your child’s immune defences. So, what can you do?

Try these ways to support your toddler’s developing body:

Check Vaccinations & Diet

This is a given, but ensure your toddler is up-to-date with vaccinations. Vaccines are crucial in preventing serious diseases.

A diet lacking in essential nutrients can also weaken the immune system. Namely, deficiencies in vitamins D and C, zinc, and iron are the most critical. So, include foods rich in these nutrients in your toddler’s meals. There’s no need for supplements unless a pediatrician recommends it.

Put in a Sleep Routine for the Whole Family

Sleep is a cornerstone of physical and mental health for kids. We all need enough sleep with a consistent routine. So, identify how many hours of sleep your toddler needs (including naps) and make it a routine for them to get just that. Check with your daycare about their nap times and ensure consistency.

Also, bring in the whole family at night! Kids are more likely to listen to you if they see that you take your own advice seriously.

Identify Stressors

Pay attention to any aspects of daily life that cause unnecessary anxiety in your child, both at home and at daycare. Stress can weaken the immune system, making children more susceptible to illnesses.

Work with your daycare’s staff or caregivers to identify sources of undue pressure and create a nurturing environment that promotes your child’s well-being.

Foods That Naturally Support Toddler Immunity

While no single food can prevent every cold or daycare bug, a healthy and balanced diet gives your toddler’s immune system the nutrients it needs to work properly.

Try to include a variety of colourful foods throughout the week. Different fruits and vegetables provide different vitamins, minerals, and antioxidants that help support your child’s natural defences.

Some immunity-supporting foods include:

Citrus fruits, strawberries, and kiwi for vitamin C
Sweet potatoes and carrots for vitamin A
Yogurt with live cultures to support gut health
Eggs and fortified dairy products for vitamin D
Beans, lentils, and lean meats for zinc and protein
Whole grains that provide important nutrients and fibre

It’s also a good idea to limit highly processed snacks and sugary drinks whenever possible. These foods can replace more nutritious options and may make it harder for children to get the nutrients their growing bodies need.

If your toddler is a picky eater, don’t worry. Focus on offering a variety of healthy foods consistently rather than trying to achieve a perfect diet every day. Small improvements over time can make a big difference.

Healthy Daily Habits That Help Prevent Daycare Illnesses

A strong immune system is built through everyday habits, not quick fixes. Simple routines can help reduce the spread of germs and support your child’s overall health while attending daycare.

Some of the most effective habits include:

Getting enough sleep each night
Washing hands before eating and after using the bathroom
Staying physically active every day
Drinking enough water throughout the day
Following recommended vaccination schedules
Eating regular, balanced meals and snacks
Spending time outdoors when the weather permits

Sleep deserves special attention. Toddlers typically need around 11 to 14 hours of sleep within 24 hours, including naps. Quality sleep helps the body recover, grow, and respond to infections more effectively.

Teaching good hygiene habits early can also make a significant difference. Even simple routines like proper handwashing and covering coughs can help reduce the spread of common daycare illnesses.

What to Do If Your Child Gets Sick

So, you boosted your toddler’s immune system and sent them off to daycare. What if they come home from daycare with a sniffle or a cough?

Here’s what to do.

Don’t Panic, it’s Healthy!

Remember that it’s natural and healthy for kids to get sick from time to time. Each illness helps their immune system grow stronger and better equipped to fight off future infections. Trust that your child’s body is learning and adapting.

There’s even a book out there written by two professors at the University of British Columbia titled “Let Them Eat Dirt: Saving Our Children from an Oversanitized World.” As the title suggests, the book says that the modern world’s overly sanitized environments have a downside regarding kids’ immune systems. Here’s a short passage from the book:

In experiments done on macaque monkeys, it was found that monkeys with the most diverse microbiota responded the best to certain diarrheal vaccines. We presume a similar concept holds true for children, again arguing for letting our kids eat dirt, and whatever else they can safely put in their mouths. It seems that having a diverse microbiota is beneficial all-around and we should provide our children with opportunities to diversify their microbiota.

Check with a Pediatrician in Case of Continued Sickness

If your toddler is always or frequently ill at daycare, it’s best to consult with a pediatrician. They can help identify underlying issues, such as vitamin deficiencies, health conditions, or environmental factors you haven’t considered.

Your pediatrician may recommend medication and vitamin supplementation or suggest further investigation to determine underlying causes.

We currently provide daycare services in three main Calgary locations:

Signs Your Child May Need Medical Attention

Most daycare illnesses are mild and improve with rest, fluids, and time. However, some symptoms may indicate that a healthcare professional should evaluate your child.

Contact your child’s doctor if you notice:

A fever that lasts longer than expected
Difficulty breathing or rapid breathing
Signs of dehydration, such as fewer wet diapers or dry lips
Extreme tiredness or unusual sleepiness
Persistent vomiting or diarrhea
Ear pain or severe discomfort
Symptoms that continue to worsen instead of improving

As a parent, trust your instincts. If your child seems significantly different from their normal self or if you are concerned about their condition, it is always reasonable to seek medical advice.

Can Daycare Actually Help Strengthen Immunity Over Time?

Many parents notice that children seem to catch more colds during their first months in daycare. While this can be frustrating, it is also a normal part of early childhood development.

When toddlers are exposed to new viruses and bacteria, their immune systems learn how to recognize and respond to them. Over time, this process helps build immune memory and can improve the body’s ability to handle similar infections in the future.

Research has found that children who attend daycare often experience more common illnesses during their preschool years, but may experience fewer common colds later in their school years compared to children with less early exposure. This does not mean children should intentionally get sick, but it does highlight how the immune system develops through normal interactions with the world around them.

Quality daycare centers help create a healthy balance by maintaining strong hygiene practices while still allowing children to learn, play, socialize, and gradually build resilience.

FAQ

How often do toddlers get sick when they first start daycare?

It is common for toddlers to experience several colds or minor illnesses during their first year of daycare. Exposure to new germs is a normal part of adjusting to a group childcare environment.

Can vitamins boost my toddler’s immune system?

Most children receive the nutrients they need through a balanced diet. Supplements may be helpful in some cases, but parents should consult their healthcare provider before starting any vitamin or supplement routine.

What is the best food for toddler immunity?

There is no single best food. A variety of fruits, vegetables, whole grains, protein sources, and dairy products provides the broad range of nutrients needed to support immune health.

Should I keep my child home from daycare when they are sick?

Yes. Keeping sick children at home helps them recover and reduces the spread of illness to other children and staff members.

Does poor sleep affect a toddler’s immune system?

Yes. Sleep plays an important role in immune function. Children who consistently get enough sleep generally have better overall health and recover more quickly from common illnesses.

How long does it take for a toddler’s immune system to adjust to daycare?

Every child is different, but many families notice fewer illnesses after the first year of regular daycare attendance as the immune system becomes familiar with more common germs.
