Every year, the same scenario repeats itself with surprising regularity. The first two weeks of school go well. Lunch boxes are packed the night before, nights are reasonable, and everyone keeps up with the routine. Then, sometime around the third week of September, a nose starts to run. Three days later, a dry cough settles in at night. A week after that, it is the youngest child’s turn, followed by a parent.
If you feel that your child gets sick as soon as they return to school, you are not wrong—and you are certainly not alone. September really is a unique month for family health. Understanding why is already a first step toward approaching fall differently.
Why September is the month of germs
Returning to the classroom suddenly changes several factors that, together, encourage respiratory viruses to circulate.
Close contact returns all at once. After a summer spent outdoors, often in small groups, a child suddenly finds themselves in an enclosed room with twenty-five other children, six hours a day, five days a week. Respiratory viruses are mainly spread through droplets released when people talk, cough, or sneeze. One classroom and one contagious child are enough to set the cycle in motion.
Shared surfaces multiply. Door handles, faucets, desks, pencils, tablets, playground balls, and school-bus handrails are touched constantly. A six-year-old touches their face dozens of times a day, often without realizing it.
Indoor air becomes dry and confined again. As soon as windows close and the heating comes on, indoor humidity drops. The mucous membranes of the nose and throat are the body’s first physical barrier against germs; when they dry out, they do not filter as effectively.
The routine changes abruptly. Sleeping in ends, six o’clock wake-ups return, extracurricular activities resume, and homework is added to the schedule. Sleep becomes shorter precisely when the body needs more rest to adapt.
Seasonal viruses begin circulating more actively. Rhinoviruses, which cause most common colds, have a well-documented peak in early fall. They never disappear completely, but they take full advantage of children gathering again at school.
No, your child does not have a “weak” immune system
It is one of the most common concerns heard in waiting rooms in September, and it is almost always unfounded.
A preschool or early elementary-school child experiences an average of six to ten upper respiratory infections per year, which is considered normal in pediatric literature. It is not a sign of fragility; it is part of the learning process. A young child’s immune system is still developing and builds its memory one exposure at a time. Every cold leaves behind useful information.
What changes with age is not so much the frequency of exposure as the speed and effectiveness of the response. At ten or twelve years old, the same virus may cause three days of nasal congestion rather than ten days of discomfort. The realistic goal in September is therefore not to avoid every cold—that would be unrealistic and, in a sense, counterproductive—but to support the child’s overall health so that episodes are shorter, better tolerated, and less frequent.
The four foundations of overall health—before any product
No product, however well formulated, can compensate for insufficient sleep. Before thinking about a back-to-school kit, it is worth reviewing the basics.
Sleep
This is by far the most powerful—and most overlooked—factor in September. Sleep needs vary by age: approximately ten to thirteen hours per night from ages three to five, nine to twelve hours from ages six to twelve, and eight to ten hours during adolescence, including naps for younger children.
If the summer schedule has shifted, do not try to correct it in one night. Move bedtime fifteen minutes earlier every two or three days until you reach the desired time. Keep the same schedule on weekends, with no more than a one-hour difference. Consistency, more than the length of any single night, is what makes the difference.
Food
There is no need for a complete dietary overhaul. Three guidelines are enough: include colour at every meal, provide a source of protein at breakfast, and watch for added sugar hidden throughout lunch-box snacks. September produce in Québec—carrots, squash, cabbage, peppers, and apples—is plentiful, affordable, and easy to incorporate.
Breakfast deserves special attention. A child who leaves for school with only juice and white toast will experience an energy drop before morning recess. An egg, Greek yogurt, peanut butter, or leftovers from the previous evening will keep them going much longer.
Hydration
Dry classroom air can be more dehydrating than we realize. A reusable bottle labelled with the child’s name, filled in the morning, and returned empty at night is a simple habit to establish and monitor. It also reduces the need to use shared drinking fountains.
Movement and daylight
Aim for thirty to sixty minutes outdoors every day, even under grey skies. Natural morning light helps reset the body clock—and therefore supports sleep—while outdoor play remains one of the best ways for children to regulate stress.
Hygiene habits that really work
Not all hygiene measures are equally useful. Three habits provide most of the benefit.
Wash hands at the right times. When arriving home, before eating, after using the bathroom, and after blowing the nose. Wash for twenty seconds with warm water and soap. For younger children, singing a familiar song from beginning to end provides a reliable measure of time.
Cough and sneeze into the elbow. Children learn this habit by imitation. If the adults at home do it consistently, the child will follow.
Do not share anything that touches the mouth. Water bottles, utensils, lip balm, and musical instruments with mouthpieces should not be shared. When explained simply, children can understand this rule as early as kindergarten.
One useful reminder for parents: toys, face coverings, and household surfaces do not need to be disinfected constantly. Regular cleaning and a few minutes of fresh air each day—even in cool weather—are generally enough.
Where homeopathy fits into the back-to-school routine
Homeopathy is based on a simple principle: stimulating the body’s natural mechanisms with highly diluted and dynamized substances. At Homeocan, this approach has been guided by a Québec pharmacist for more than thirty-six years, with a constant focus on adapting it to the realities of families.
In the back-to-school context, the appeal is twofold.
First, tolerability. Oral solutions in the Kids 0-9 line are formulated without gluten or added sugar and do not cause drowsiness. For a child who needs to spend the day in class, the absence of a sedating effect makes a practical difference.
Second, ease of administration. Oral solutions are easy to give, including to children who refuse tablets, and the dosing instructions are designed to be followed by a parent without specialized training.
Homeopathy helps relieve symptoms associated with minor and seasonal conditions. It does not replace medical advice, prescribed treatment, or vaccination. It is part of a broader approach in which sleep, nutrition, and hygiene remain the priorities.
Building a back-to-school health kit
The goal is not to buy a large number of products, but to have appropriate options available for the most common situations in September and October—preferably before they are needed at nine o’clock on a Tuesday evening.
Runny or stuffy nose. This is the number-one back-to-school symptom. Keep an age-appropriate option on hand, along with saline solution for nasal rinsing, which is especially helpful for young children who do not yet know how to blow their nose.
Cough. Distinguish between a dry cough, which is often irritating and worse at night, and a wet cough. The formulations are different, and the Children’s Cold, Cough and Flu collection can help you choose.
Sore throat. Common at the beginning of an infection, a sore throat can go unnoticed in a child who does not describe it and simply eats less.
Fatigue and low energy. After three or four weeks of the school routine, an energy slump is common. The Immune System and Low Energy collection brings together options for these transition periods, including tissue salts for families looking for foundational mineral support.
Nervousness, worries, and restless sleep. Back to school is not only about germs. Bach Flowers are often one of the first options parents consider to support children through September emotions, particularly when a child is changing schools or teachers.
Minor playground mishaps. Bumps, bruises, and scrapes are part of active school days. Keeping Traumacare cream in a backpack or the entryway cupboard can help avoid unnecessary last-minute trips.
For infants and toddlers, the Le Petit Prince line offers formats designed specifically for this age group.
When to seek medical advice
Supporting your child’s overall health at home has limits, and recognizing them is part of a responsible approach. Seek medical advice promptly if you notice:
- any fever in an infant younger than three months;
- a fever that lasts longer than seventy-two hours or returns after improving;
- difficulty breathing, wheezing, pulling in between the ribs, or bluish lips;
- signs of dehydration, including a dry mouth, no tears, significantly fewer wet diapers, or unusual drowsiness;
- severe ear pain or discharge;
- a worsening general condition, or a child who is unusually lethargic or difficult to wake;
- a cough lasting longer than three weeks.
When in doubt, Info-Santé 811 is available at all times in Québec.
The first thirty days: a simple plan
Week 1. Set a bedtime and keep it, including on weekends. Establish a handwashing routine when everyone arrives home. Label the water bottle.
Week 2. Check breakfast: is there a source of protein? Go outside every day, even for fifteen minutes. Take inventory of the health kit and add anything that is missing.
Week 3. Statistically, this is often when the first cold appears. Do not panic. Slow the schedule down instead, even if it means skipping an activity. A child who gets an extra hour of sleep for three nights often recovers more quickly.
Week 4. Take stock. If fatigue continues despite adequate sleep, it is time to speak with a health care professional rather than waiting until December.
Frequently asked questions
My child has had four colds since September. Is that normal? Yes, in the vast majority of cases. Six to ten respiratory infections per year are expected in young children, and they naturally occur more often during the school year. What deserves attention is an infection that does not resolve, a persistent fever, or fatigue that does not improve with rest.
Can homeopathic products be given at the same time as prescribed medication? Speak with your pharmacist or physician, who knows your child’s complete medical history. As a general rule, homeopathy is not intended to replace an existing treatment.
At what age can the Kids 0-9 line be used? The line is designed for children from birth to age twelve, with dosing that varies by age. Always follow the product label.
Should children take vitamin supplements when school begins? They are not usually necessary for a child who eats a varied diet. Vitamin D is an exception at our latitude from October to April, and it is worth discussing with your health care professional.
In summary
September will always be a demanding month for the family’s natural defenses. But there is a real difference between simply enduring the season and being prepared for it, and that difference comes down to a few basic habits: protecting sleep, washing hands at the right times, bringing home an empty water bottle, and keeping a small health kit ready in the cupboard.
