1. Encourage regular handwashing
We know it may sound obvious but you'd be surprised how many little ones dodge a thorough hand wash for a quick splash under the tap. Teach them from a young age to use warm water with soap and scrub for at least 20 seconds. The NHS says a useful trick is to sing "Happy Birthday" twice to make sure they're doing a thorough job.
“The only things we do to prevent illness are wash hands when we come home from school and always have windows open at home (as I like fresh air).” Devongirl1983 says.
“It's improving now in Year 4. But they need to learn to wash hands, blow noses properly, not cough on each other etc.” Harrysmummy246 added.
2. Eat balanced meals and supplement smartly
A colourful lunchbox packed with fresh fruit and vegetables, wholegrains, healthy fats and protein can help keep children fuelled for the school day while supporting their immune system. Some Mumsnetters also include probiotic foods such as live yoghurt and kefir as part of their family's diet. And many opt for additional support with daily gut and immune health supplements for better resilience against classroom germs.
As with any supplement for children, it's worth checking what's appropriate for their age and speaking to a pharmacist or healthcare professional if you're unsure.
For Mumsnet user RocketNan, Sambucol Black Elderberry immune support supplements are part of the family routine: “I highly recommend Sambucol for kids. Both mine take it from September to March. Would not be without it. One is at university now and still takes it.”
3. Get back into a good sleep routine
It's easy for bedtimes to slip during busy weeks, after-school clubs or half-term breaks, but good sleep is essential as it gives kids the chance to rest and recharge and helps support their immune systems.
If bedtime's drifted later than you'd like, try bringing it forward in 15-minute increments so the change doesn't feel as sudden. And if you're struggling to get them to wind down, our Mumsnet users say lower lights, soothing music and warm baths can all work a treat.
