If your child seems to bring home every cold going around, you’re not alone. There are more than 200 known respiratory viruses that cause colds, and they spread quickly, especially in schools, daycare centers, and busy households. But while you can’t prevent every sniffle, you can reduce the number of colds your child catches by supporting their immune system and minimizing germ exposure.
The following five simple strategies help parents support their children’s health, reduce the risk of seasonal illness, and recognize when it’s time to bring their child to our trusted providers at Caldwell Urgent Care and Family Medicine.

1. Teach Proper Handwashing—and Make It a Habit
Kids touch their faces dozens of times per hour, which makes it easy for cold viruses to enter their bodies through the eyes, nose, or mouth. One of the simplest and most effective ways to prevent colds is consistent and thorough handwashing. Here’s what to teach your child:
- Use soap and warm water. Scrub hands for at least 20 seconds—about the length of the “ABC” song.
- Wash after key activities. This includes using the bathroom, blowing their nose, playing outside, and before eating.
- Use sanitizer when needed. Alcohol-based hand sanitizer is a good backup when soap and water aren’t available.
2. Focus on a Whole-Food Diet Low in Sugar
Your child’s immune system is fueled by what they eat. An eating plan rich in whole, nutrient-dense foods helps the body fight off viruses and recover faster if they do get sick. Foods that support immunity:
- Fruits and vegetables. Colorful produce provides antioxidants and vitamins such as C and A.
- Lean proteins. Chicken, turkey, eggs, and legumes help build immune cells.
- Probiotic-rich foods. Yogurt with live cultures may support gut health, which is closely tied to immune function.
- Limit sugary snacks. High sugar intake often suppresses immune activity for hours after eating.

3. Keep Germy Items Clean
Kids share everything—including germs! High-touch items, such as toys, water bottles, lunchboxes, and backpacks, have the potential to harbor viruses for extended periods after exposure. So, what can you do?
- Encourage daily backpack clean-outs. Papers, tissues, and food wrappers accumulate bacteria.
- Clean toys weekly. Focus on shared items or favorites that your child frequently handles.
- Disinfect electronics. Phones, tablets, and game controllers are often overlooked.
4. Prioritize Sleep and Restful Routines
Kids need more sleep than adults—but busy schedules and screen time can cut into critical rest. Poor sleep weakens the immune system, making it harder for the body to fight off infections. Recommended sleep amounts include:
- Preschoolers (3–5 years): 10–13 hours
- School-age kids (6–12 years): 9–12 hours
- Teens (13–18 years): 8–10 hours
Additionally, maintain a consistent bedtime—even on weekends—and limit screen exposure at least an hour before bed to support quality sleep.
5. Encourage Daily Movement and Outdoor Play
Regular physical activity is more than just good for growing muscles—it strengthens your immune system, improves sleep, and reduces stress, all of which help prevent colds in children. Even in cooler weather, getting kids outside for fresh air and exercise is one of the best ways to support their health. Need some ideas to encourage your children to stay active? Try these:
- Bundle up and play outside. A brisk walk, sledding, or game of tag gets blood flowing and clears indoor germs from the lungs.
- Limit sedentary screen time. Encourage breaks every hour for stretching or movement.
- Make physical activity fun. Dance parties, obstacle courses, and indoor scavenger hunts are great alternatives for extremely cold days.
Daily movement boosts circulation and helps immune cells travel more efficiently throughout the body—making it easier to fight off illness before it starts.
When Should You Bring Your Child to Our Idaho Urgent Care?
Fortunately, most children with cold or flu symptoms don’t need emergency treatment. Even when they feel run-down or need to stay home from school, rest, fluids, and over-the-counter remedies are usually enough to support recovery.
However, some colds can develop into more serious conditions. Watch for the following signs that it’s time to seek care from the dedicated providers at Core Medicine of Idaho:
- Fever lasting more than three days.
- Breathing difficulties or persistent wheezing.
- Constant ear pain.
- Severe sore throat.
- Fatigue that doesn’t improve with rest.
- Dehydration, especially when it presents as dry mouth, no tears, and reduced urination.
Prompt medical attention can shorten illness duration and prevent complications like ear infections or pneumonia.
Creating a healthier home doesn’t require major changes—just consistent habits that help protect your child’s immune system. But, if you ever have a concern or need more information, don’t hesitate to schedule a consultation with us.
