The Ultimate Guide to Allergenic Foods: What to Introduce and When
Introducing allergenic foods can feel daunting, but recent research shows that early introduction may actually help reduce the risk of allergies. According to *Solid Starts* and *Weaning Sense*, it’s safe—and often beneficial—to introduce common allergens from around 6 months of age, as long as your baby shows signs of readiness.
What Are the Top Allergenic Foods?
The most common allergens include:
- Peanuts
- Eggs
- Dairy
- Tree nuts
- Soy
- Wheat
- Fish and shellfish
- Sesame
When to Start
Start offering these foods one at a time, ideally during the day when you can watch your baby afterwards. A good starting point is around 6 months, once your baby is confidently managing first tastes.
How to Introduce Allergens
- Start small: a tiny amount mixed into something your baby already tolerates.
- Wait 2–3 days before introducing a new allergen.
- Keep offering it regularly once tolerated—repetition helps build tolerance.
Signs of an Allergic Reaction
Reactions typically happen quickly (within minutes to two hours). Watch for:
- Rash or hives
- Swelling of lips or face
- Vomiting
- Difficulty breathing (seek emergency help immediately)
What About High-Risk Babies?
If your baby has eczema or a family history of allergies, speak to a paediatrician or allergist before introducing allergens. They might recommend an earlier or more cautious introduction.
Remember, most babies tolerate these foods just fine, and the earlier introduction (around 6 months) is now seen as protective, not risky. The key is to go slowly, be observant, and follow your baby’s lead.
And no matter what, you're not alone in this journey. Every new food is a step forward.
