Safely Introducing Allergens to Your Baby
Recent research (like the LEAP study) has completely changed guidelines: delaying allergens increases risk. We now recommend early introduction.
The Top 9 Allergens
These account for 90% of food allergies:
- Peanuts
- Tree Nuts (Cashew, Walnut)
- Egg
- Milk (Cow's dairy)
- Wheat
- Soy
- Fish
- Shellfish
- Sesame
How to Introduce Safely
1. Timing
- Low Risk: Start around 6 months with other solids.
- High Risk (Eczema/Egg Allergy): Consult pediatrician; may start as early as 4-6 months.
2. Method
- Texture: Never give whole nuts or globs of nut butter (choking hazard). Thin it with water, breastmilk, or mix into oatmeal.
- Quantity: Start small (e.g., 1/8 teaspoon). If tolerated, gradually increase.
- Setting: Do it at home, in the morning (to observe for 2 hours).
3. The 3-Day Rule (Modified)
When introducing a top allergen, offer no other new foods for 3 days to pinpoint any reaction.
Recognizing a Reaction
- Mild: Hives around mouth, few spots on body.
- Severe (Anaphylaxis): Swelling of lips/tongue, difficulty breathing, vomiting, widespread hives, limpness.
- Action: Stop feeding immediately. For severe symptoms, call 911/Emergency.
Maintenance
Once introduced and tolerated, keep the allergen in the diet regularly (e.g., 2-3 times a week) to maintain tolerance.
