@iryna_klevetenko have you seen our “Immune Support for Kids” protocol? It includes guidance on what to use when a child is starting to get sick and how to support recovery, but it’s not meant for continuous, year-round use.

At 23 months, it’s actually very common for little ones to catch frequent colds once they start nursery. This phase helps build their natural immunity as they’re exposed to new microbes and develop stronger defenses over time.

The best defense is through daily nourishment, sunshine/vitamin D and gut support – things like probiotic-rich foods, daily sun exposure and/or supplements (if needed to maintain optimal levels), and nutrient-dense meals with plenty of vegetables, proteins, and healthy fats to help their system recover and stay resilient.

Cod liver oil is one of those superfoods that I personally like for children as it combines vitamin D and A for immunity, and omega-3 for inflammatory and overall immune support, and brain development. Also, try to limit sugar, juice, refined grains, and processed or fried foods, as these can weaken immune defenses.

Hope these help.
