Allergen introduction with confidence: when, what, and how to react

Introducing common allergens to your baby is a significant milestone, and it's completely normal to feel a great deal of anxiety about it. With so much information available, it’s easy to feel overwhelmed by the "when, what, and how" of the process. The goal is to approach this step with a feeling of confident preparation, not fear.

It is highly unrecommended to rely on outdated advice or generalised information from the internet, which can cause parents to delay introduction out of fear. The most important thing to remember is that the strategy for introducing allergens is a medical plan that you should create in direct partnership with your pediatrician.

The first and most crucial step is to talk to your doctor about the right timing for your specific baby. Official guidelines on this topic have evolved over the years, and your pediatrician will provide the most up-to-date recommendation based on your baby's individual health, development, and any family history of allergies. They can help you create a plan for introducing common allergens like milk, eggs, peanuts, soy, and wheat.

It is vital to know the potential signs of an allergic reaction so you can act quickly. A reaction can range from mild symptoms like hives, a rash, or an upset stomach, to severe symptoms like swelling of the lips, tongue, or face, or difficulty breathing. Your role is not to diagnose the reaction, but to recognize a potential problem and seek immediate medical help. For any severe symptoms, you should call emergency services right away. For any mild symptoms, stop the feeding and contact your pediatrician for guidance.

To ensure you can observe your baby carefully, it is best to introduce a new allergen for the first time at home, during the daytime when they will be awake for a few hours. This careful planning, done in collaboration with your doctor, is the safest and most effective way to navigate this process.
