If it feels like your kid is sick almost every week, you’re not imagining it. Kids under the age of 6 in particular get 8 to 10 colds a year, not including the countless fevers, infections and stomach bugs they’ll get this year.

Kids are like little Petri dishes for germs, especially when they’re in daycare and school. They all touch the same surfaces, share the same toys and put everything in their mouths.

They all have to wash their hands after they use the bathroom and before meals but are they using enough soap and washing properly? It’s questionable.

When my daughters started school last year, I was prepared for them to get sick—a lot. Although they had a few fevers and colds, and one had norovirus, for the most part they were relatively healthy.

Did we get lucky? Maybe.

But more likely, it was a because of a few things I did to improve their immunity which might help your kid too.

Cut the crappy food

Since the gut makes up to 70 percent of the immune system, making sure your kid’s gut is healthy can also boost his immune system.

If your kid lives on foods that come out of a bag, box, or package, however, he could be missing key vitamins and minerals that keep him healthy and his immune systems strong.

Experts say eating foods that are processed and filled with sugar over the long term could lead to intestinal permeability or leaky gut syndrome. Leaky gut occurs when the tight junctions in the large intestine open and allow undigested food particles and pathogens in, which in turn elicits an immune response.

Leaky gut syndrome has been linked to various conditions including allergies, asthma, fatigue, autoimmune diseases, migraines and inflammatory bowel disease (IBD).

Eat the rainbow

A whole foods diet that contains plenty of fruits and vegetables of all colors gives your kid the nutrition she needs for a strong immune system. Yet they also contain prebiotics, or non-digestible food ingredients, that work with probiotics, the live microorganisms found in the gut, to grow and work to boost your child’s immunity.

Add fermented foods

Kefir tastes too tangy for me but my kids love it and that’s a good thing. The probiotics found in kefir and other foods like yogurt, kimchi, naturally fermented vegetables, including sauerkraut and pickles can help improve gut health and boost your child’s immune system.

Take probiotics

Probiotics have become popular in recent years, particularly for their ability to improve gut health, experts say. Some studies show probiotics can shorten the duration of diarrhea associated with a stomach virus or a course of antibiotics and may reduce upper respiratory infections.

It’s important to note that the American Academy of Pediatrics (AAP) hasn’t recommended regular use of probiotics in children because there’s a lack of evidence for their efficacy. Of course like any supplement, if you want to give your kid probiotics, check with his pediatrician first.

Move more

My kids are constantly in motion and they play at the park and the playground, take movement classes and after-dinner walks, but I still find getting them 60 minutes exercise a day a challenge. Nevertheless, I do my best to make sure they get some form of exercise in every day.

Exercise has so many benefits for kids, and as it turns out, can improve their gut health and immunity. In fact, a study in the journal Gut shows exercise may diversity gut microbes.

During the dog days of winter or on snow days when you can’t get out, put on music and have a dance party or enjoy a game of Twister.
