How to Support a Toddler’s Immune System Naturally: 7 Mum-Approved Tips

Tháng 9 18, 2025

The start of a toddler’s sniffle can be a Mum’s worst nightmare, the cascade of thoughts of; who’s going to get sick next, do I have any sick days left? and I wonder if I can still drop them at daycare? Hmmmm, nope. The next train of thought as she runs for the tissue box; how do I support my kid’s immune system, is it gut health, is it vitamin C? There are so many options these days.

Why Toddlers Need Immune System Support

Even from before your child was born, they are building their immune system, but now they are here and growing fast they seem to be picking up every bug under the sun. Like many things in life there is a balance, and even with immune health there is a balance, you don’t want an under-functioning immune system, but you don’t want an over-stimulated immune system either. Exposure to new pathogens is part of building a resilient immune system for life.
Your little bundle of joy will be moving from a passive immune system where they receive antibodies from their mother’s breast milk (if possible), to where their adaptive immune system starts to develop as they encounter germs and pathogens. Every time the immune system comes across a new germ, it learns to recognize it as foe, rather than friend, and therefore learns to fight it off and stores it in its memory to respond quicker in the future.
Gone are the days in recent history where we thought sanitizing every single thing was good for our babies, and now we have understanding that they need bugs from their environment to support their microbiome and developing immune system and that licking the dog and eating dirt is a good thing.
Building resilience naturally is important for your child’s immune system, not just for now while they are little but for the long term.
Let’s check out 7 ways you can support your toddler’s immune system, naturally.

1. Prioritise Sleep and Routine

Let’s start with bedtime. Sleep is one of the most important factors in your preschoolers immune building life! But sometimes it’s the hardest code to crack.
Studies have shown the link between sleep duration and immune markers (cytokines: IL-6 and TNF-α) in preschool children, in other words, the appropriate amount of sleep showed an increase in immune system function.
But what is the appropriate amount of sleep for a toddler?
Ages 3 – 5 should be getting around 10 – 13 hours of sleep, plus naps for some children during the day as well.
A consistent bedtime routine is super helpful, so choosing the same time every night and having a wind down routine like reading a book is essential to support the little one’s sleep.

2. Offer a Balanced, Colourful Diet

We’ve all heard “Eat the rainbow” which is the truth for your immune system, because each colour in your fruits and vegetables contain different “superpowers”. These superpowers are called antioxidants which reduce free radicals that can cause damage to our cells, including our immune cells. So, for a robust immune system, always offer a variety of fruit or vegetable options and make sure to keep offering them many times over. It can take 8 – 12 times of being offered the same food before they like it, persistence is key!
Many plant-based foods offer a multitude of vitamins and minerals for our youngsters to thrive, but don’t forget the essential nutrients they get from animal-based foods. Eggs, dairy, organ meats and meats are all nutrient powerhouses that support not only your child’s growth and development but their immune system too: Zinc, magnesium, iron, B vitamins, and especially vitamin B12 which isn’t found in plants.
Don’t forget fermented foods that are rich in probiotics, like yogurt, kefir, sauerkraut and miso. These support your toddlers gut health and therefore their immune system, just add a tiny bit into their favourite foods and build it up slowly.

3. Support Gut Health with HMOs

We’ve all heard about gut health and how it’s important for the immune system, but have you heard of Human Milk Oligosaccharides (HMO)? They are present in human breast milk and are just one of the wonderful ways breast milk supports your baby’s immune system. HMOs may support immune function development in young children and provide immune support directly through the interaction of the gut lining or indirectly through the gut microbiome, including the support of the bifidobacteria. Two well-studied forms of HMOs are 2′-fucosyllactose (2′-FL) and Lacto-N-neotetraose (LNnT), these have been shown to support the good gut bacteria and therefore support the infants developing immune system.
Good Health Viralex® Kids Immune Powder has been formulated to include these two immune supporting compounds to better serve our young population.

4. Try Scientifically Researched Immune Nutrients

As a busy Mum, you’ll be on the lookout for the best support for your preschoolers, look no further than Good Health’s Viralex® KidsViralex® Kids Immune Powder. We know that vitamin C and zinc are essential immune support ingredients and of course they are included in both our Viralex® Kids products. Vitamin C is a powerful antioxidant that supports the body’s cells and immune system, and zinc supports the maturation of immune cells and well as healing time.
But you may not have heard of Wellmune® beta-glucan! This is another potent ingredient that has actually been scientifically studied on children and has been shown to support their immune systems, so they have less days off daycare. It’s a natural yeast beta 1, 3/1, 6 glucans derived from Saccharomyces cerevisiae that supports overall health and wellness by supporting the body’s immune system. It supports the key immune function of neutrophils to be ready when needed in the body.

5. Limit Sugar and Avoid Overuse of Antibiotics

The dreaded sugar monster battle where sometimes the SuperMum comes off second best. It’s tough out there but reducing your preschoolers sugar intake is worth it on many levels. Sugar can impact the immune system in a negative way, so it’s best to keep it to a minimum especially if they are already sniffly. Another battle that is important to know when to pick and choose is the use of antibiotics. Most of the time, your child’s immune system can support them against harmful bacteria. However, antibiotics are
sometimes required. Talk to your doctor, use your discretion and always utilise a probiotic at the same time as antibiotics tend to disrupt the gut flora.

6. Encourage Outdoor Play and Sunshine

One of the best things you can do for your child is playing outdoors, especially if it’s in the dirt, with other children and with pets! The exposure to new helpful bugs that support their microbiome and immune system is invaluable.
Of course, the bonus of being outside is exposure to sunlight which stimulates vitamin D production naturally in the body. As we know vitamin D is important for many things in the body including immune system health.

7. Make Immune Support Part of Your Daily Routine

No parent likes seeing their child sick, but at this young age it is part of developing a robust immune system. That said, the tips we have provided here are some very simple and proven ways to support your toddler’s immune system as they grow. It’s a busy time for families, so consistency with wholefood choices, regular bedtimes, outdoor play and by adding in supplemental support into your toddler’s smoothie or yogurt such as Good Health’s Viralex® Kids Immune Powder can give parents additional peace of mind.
