Cold & Flu Prevention for Kids


Your family’s easy guide to staying healthy this winter.
Cold and flu season is here, so I’m sharing some simple habits that can help keep your kids healthy. The best part is that these strategies are easy to work into everyday life!
Handwashing Really Works
Hand hygiene is one of the simplest and most effective ways to prevent illness. Wash with soap and water for 20 seconds (sing “Happy Birthday” twice) or use alcohol-based sanitizer when soap and water aren’t available. Wash before eating, after the bathroom, after nose wiping, and when arriving home.
Sleep Strengthens the Immune System
A good night’s sleep helps kids fight off germs. Children who don’t get enough sleep are more likely to catch respiratory infections. Tips that help: stick to a bedtime routine, limit screens before bed, keep bedrooms cool and calm, and avoid caffeine for teens.
Flu Shots: Still the Best Protection
All children 6 months and older should get a yearly flu vaccine. It’s the most effective way to prevent the flu and protect those around you.
What About Supplements?
There isn’t strong evidence that probiotics or other supplements prevent or treat cold symptoms in young children. Prevention through vaccination, sleep, and good hygiene remains the most reliable approach.
When Kids Get Sick
Even with excellent prevention, colds are part of childhood. Most don’t need special treatment, and over-the-counter cold medicines are not recommended for young children. For the flu, antiviral medications can help when started early, especially for children who are hospitalized, have underlying conditions, or have severe symptoms. Check in with your pediatrician within 48 hours of symptom onset if you think your child has the flu.
The Bottom Line
Three habits that make a real difference:
- Practice good handwashing.
- Make sleep a priority.
- Get the annual flu vaccine.
