As toddlers grow, the emergence of allergies and intolerances can present unexpected challenges for parents along with them. Allergies occur when the immune system reacts to specific substances, while intolerances come from the body’s difficulty processing certain foods. Recognizing and handling allergies and intolerances in toddlers is crucial for their health. In this article, we explore allergies and intolerances in toddlers, looking at the signs and reasons behind them. This knowledge will help parents make a safe and nurturing space for their little explorers to grow.

1. Understanding Allergies and Intolerances

Understanding the differences between allergies and intolerances is crucial for proper identification and management.

a. Allergies

Allergies happen when the body’s immune system reacts to certain things called allergens, which it thinks are not safe.

b. Intolerances


Intolerances are bad reactions to certain foods or substances without involving the immune system.

c. Key Differences

The critical difference between allergies and intolerances lies in their underlying mechanisms, with allergies being related to your immunity and intolerances being non-immune-related.

Parents can protect their kids from exposure and responses by being aware of common allergies.

a. Food Allergens

Common food allergens include milk, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish.

Environmental allergens such as pollen, pet dander, dust mites, and mould spores can trigger toddler allergies.

c. Contact Allergens

Certain substances, like soaps, detergents, or latex, can cause skin reactions in toddlers with contact allergies.

Intolerance symptoms may include stomach pain, bloating, gas, diarrhoea, and skin rashes, but they do not involve the immune system.
