How Not To Get Sick When Daycare Germs Come Home

Daycare offers a lot of benefits and one big drawback: germs. (But rest assured, if your kid skips daycare, when they get to preschool or kindergarten, they'll likely get some of the illnesses they missed.) From the common cold to stomach bugs, kids start getting sick shortly after starting daycare. And when one family member gets sick, it’s often only a matter of time before the rest follow.

The ripple effect of a daycare illness can turn a household upside down—missed work, sleepless nights and cranky siblings. It’s a cycle parents know all too well.

To help you reduce the chaos and prevent the spread of germs, here are expert-backed strategies to minimize the spread of daycare germs once they come home.

Why is daycare such a hotspot for germs?

If it feels like your child has a runny nose every other week since starting daycare, you’re not imagining it. Group settings like child care centres are prime environments for spreading germs.

Young children’s immune systems are still developing, making them more vulnerable to common viruses and bacteria, many of which they’re encountering for the first time. Kids share toys, touch the same surfaces and often forget to cover coughs or sneezes. Toddlers also explore the world with their hands and mouths, increasing germ exposure even more.

“It is very common for toddlers and pre-school-aged children to have as many as eight to 12 colds, respiratory infections and/or stomach bugs a year,” says Dr. Natasha Collia, a pediatric emergency physician. “Infants who have older siblings who are in school will also tend to get sick more frequently, since their siblings are bringing home germs.”

While this constant cycle of illness can be frustrating, it’s also a normal part of immune development. Most of these illnesses are mild, but knowing how to respond at home can make a big difference.

Common illnesses kids bring home from daycare (and what to expect)

With so many children in close contact, it’s no surprise that certain illnesses make regular rounds in daycare. Most are viral and resolve on their own, but knowing what to expect can help you manage symptoms and stress.

The common cold

Typical common cold symptoms include a runny nose, sneezing, mild cough, sore throat, fatigue and possibly a low-grade fever. These usually last seven to 10 days but can linger longer in young kids. Children may catch multiple colds a year as their immune systems mature. Despite symptoms, most kids still have the energy to play and follow their usual routines.

Influenza (flu)

Unlike colds, the flu comes on fast with a high fever, chills, body aches, and extreme fatigue. Children are often bedridden and may need extra rest even after symptoms ease. Fever and muscle aches typically last two to four days, while lingering tiredness can last longer.

Children over six months should receive an annual flu shot, and it’s recommended that all eligible family members do the same.

Gastroenteritis (stomach flu)

Vomiting, diarrhea, stomach cramps and occasional fever are signs of viral gastroenteritis, often caused by norovirus or rotavirus. These bugs spread easily through contaminated hands, surfaces or food.

“A lot of kids don’t wipe properly, and they don’t wash their hands effectively when they wipe,” says Dr. Robin Baweja, MD, pediatrician and founder of Dear Mommy. “So that’s when things spread, especially those diarrheal illnesses we see.”

Symptoms usually clear up within three days, but keeping your child hydrated is key to recovery.

Hand, foot and mouth disease

This viral illness can fly under the radar early on. According to Dr. Baweja, hand, foot and mouth disease often goes unnoticed because kids may only show a fever at first.

“They don’t feel well, they feel really tired and then they’re refusing to eat and parents can’t figure out why,” she says. “Until they actually look into their mouth and see some lesions.”

These lesions often have a whitish rim with a darker red outer edge and can resemble small blisters. “They have a bit of a volcano look,” says Dr. Baweja. They commonly appear along the sides of the tongue, the roof of the mouth and the inner gums. Similar pinpoint lesions may also appear on the hands, though they can be easy to miss.

Most cases resolve within a week to 10 days. Children should stay home until their fever has subsided and their mouth sores are healing to reduce the risk of spreading the virus.

Respiratory Syncytial Virus (RSV)

RSV starts like a cold—runny nose, congestion and cough—but in some children, especially infants or those with health conditions, it can lead to wheezing or breathing trouble.

Seek medical care if your child has a fever lasting more than 72 hours, refuses fluids, isn’t producing wet diapers, or shows signs of respiratory distress. Head to the ER if their lips turn blue or breathing becomes laboured.

Practical steps for staying healthy

When your child brings home daycare germs, the rest of the family, especially parents, are often next in line. While you can’t avoid every bug, a few daily habits can help you stay well and keep the household running smoothly.

Prioritize hand washing

Consistent hand washing is the most effective way to avoid getting sick. Be sure to wash your hands:

• After daycare pickup
• After wiping noses or changing diapers
• Before eating or preparing food
• After helping your child in the bathroom

Use warm water and soap, scrub for 20 seconds and dry with a clean towel. Hand sanitizer with at least 60 percent alcohol is a backup when soap isn’t available.

Support your immune system

No need to overhaul your life—small habits make a big difference:

• Get seven to eight hours of sleep every night
• Eat a balanced diet rich in fruits, vegetables and protein
• Move your body daily, even if it’s just a walk

Manage stress

High stress levels can weaken your immune system. Try to fit in:

• Brief breathing or mindfulness exercises
• A walk outdoors
• Ten minutes of quiet time to recharge

Even small moments of calm can improve your body’s resilience.

Get your flu shot

Everyone in the household over six months should get an annual flu shot. It reduces the risk of serious illness and helps protect vulnerable family members.

Don’t skip rest

If you feel run down, take it seriously. Resting at the first sign of illness can prevent something minor from getting worse. Go to bed earlier, delegate tasks and let yourself slow down when needed.

How to minimize illness spread to other children at home

When one child comes home sick from daycare, it often feels like a countdown until everyone else gets it, especially siblings who share everything. While total containment isn’t always possible, these strategies can help reduce the spread.

Create a “sick zone”

If space allows, have your sick child rest in a designated area with their own blanket, toys and water bottle. This doesn’t mean isolating them completely, but it helps create some distance during the most contagious period.

Reinforce hand hygiene

Make sure both sick and healthy kids wash their hands:

• After coughing or sneezing
• Before meals
• After using the bathroom
• After touching shared toys or surfaces

Younger kids may need reminders or supervision to scrub properly.

“Teach kids to use tissues to blow their nose and to sneeze or cough into their elbows,” says Dr. Collia. “This helps limit how far droplets travel.”

Press pause on sharing

During illness, temporarily separate:

• Cups and water bottles
• Snacks and utensils
• Towels and washcloths
• Toys that are hard to clean or go in mouths

Reassure siblings that these rules are temporary—and for everyone’s protection.

Step up cleaning

Viruses like RSV and norovirus can live on surfaces for hours. Wipe down high-touch items like doorknobs, remotes, faucet handles and shared toys more often than usual.

A bath or shower after daycare can help wash away germs, especially during cold and flu season. “Consider changing your child into fresh clothes when they get home, especially if they’ve been sneezing, coughing, or had any episodes of vomiting during the day,” says Dr. Collia.

Watch for symptoms

Keep an eye on healthy siblings, especially infants or children with underlying health conditions. Subtle changes like fatigue, irritability, or a reduced appetite may be early signs of illness. Catching it early can help minimize the spread.

Daycare sick policies and knowing when to keep your child home

Figuring out when to keep your child home can be tricky, especially when symptoms are mild or they seem mostly fine. But understanding your daycare’s illness policy and watching for key signs can help protect your child, classmates,and caregivers.

Know the policy

Every daycare is different. Some have stricter illness rules than others, so ask for a copy of their guidelines and clarify anything you're unsure about. Open communication with staff helps set shared expectations and prevents confusion.

When to keep your child home

• Fever: 100.4°F (38°C) or higher: Most centres require children to be fever-free for 24 hours without medication before returning.
• Vomiting or diarrhea: Especially if it happens more than once in 24 hours or your child is showing signs of dehydration.
• Persistent cough: If it’s frequent, disruptive, or paired with other symptoms like trouble breathing.
• Unexplained rash: Particularly if it’s spreading, itchy, or accompanied by fever.
• Pink eye: Most daycares require kids to stay home until treated or cleared by a doctor.
• Lethargy or behaviour changes: If your child seems especially tired, irritable, or “off,” it’s worth keeping them home.

Trust your gut

You know your child best. Even if they don’t meet all the criteria, keeping them home is OK if they’re clearly not themselves or need extra rest. While it’s never convenient, staying home when sick helps protect others and may help your child recover more quickly.

Long-term strategies to combat daycare illness

While you can’t shield your child from every bug, small daily habits at home can help reduce illness and support your family’s health.

Reinforce hygiene and healthy habits

Make hygiene a shared family responsibility—not just something practiced at daycare. Encourage:

• Regular handwashing, especially after bathroom use and before meals
• Covering coughs and sneezes with elbows
• Staying home when feeling unwell

Visual reminders help, especially for young kids. Dr. Baweja suggests putting up simple handwashing guides near sinks and occasionally checking that children wash properly after using the bathroom.

Improve air quality

Good airflow supports respiratory health, especially during cold and flu season. You can:

• Open windows to let fresh air in (when weather permits)
• Use kitchen and bathroom exhaust fans
• Run a HEPA-filter air purifier

If you use an air purifier or cool mist humidifier, clean it regularly. Dr. Baweja notes that if not properly maintained, these devices can harbour bacteria and mould, which may worsen symptoms or cause illness.

Establish a toy cleaning routine

Shared toys can carry lingering germs. To help reduce risk:

• Clean plastic toys weekly with soap and water or disinfectant wipes
• Machine-wash stuffed animals and soft toys
• Disinfect high-touch items like remotes and doorknobs regularly

Focus on nutrition, sleep and movement

• Immune health starts with consistent routines:
• Offer a variety of whole foods, including fruits, vegetables, and lean proteins
• Ensure kids get enough sleep (10–14 hours depending on age)
• Build in active play daily—even a walk or dance session counts

Consider probiotics (with caution)

Some parents explore probiotics to support gut and immune health. While research is ongoing, ask your child’s doctor whether they’re appropriate, especially if your child frequently gets sick.

The bottom line

Daycare offers kids valuable opportunities to learn, play, and grow—but it also introduces them to a steady stream of germs. While catching colds and bugs is a normal part of childhood (and immune system development), it doesn’t mean families are powerless.

With smart routines—like handwashing, better sleep, balanced meals, and clear communication with your daycare—you can reduce how often illness spreads and ease the impact when it does. Creating a healthier home environment and knowing when to keep your child home from daycare are also key to minimizing disruptions.

Most importantly, remember: you’re not alone in this. Daycare germs affect every family at some point, but with proactive steps and a little planning, you can navigate this season with more confidence and less chaos.
