Introducing allergens to your baby might sound scary, but it’s one of the best things you can do for their health! Gone are the days when parents waited years to give their little ones peanuts, eggs, or fish.
Today’s doctors recommend starting these foods early, around 4-6 months old, to prevent allergies from developing.
Babies who try peanuts before their first birthday are 80% less likely to develop peanut allergies!
Think of it like teaching your baby’s immune system to be friendly with different foods instead of treating them like enemies.
The key is starting small and watching for reactions. You’ll want to introduce one new allergen at a time, kind of like introducing new friends to your baby’s tummy.

Why Early Introduction Matters
Did you know that introducing babies to common allergy foods early can help prevent allergies? It sounds backwards, but science proves it works! Two significant studies changed everything:
- LEAP Study (peanuts): Babies who ate peanut foods early had 80% fewer peanut allergies
- EAT Study (multiple foods): Early introduction reduced allergies to eggs, milk, and other foods
When should you start? Between 4-6 months old, but definitely before your baby turns one year old.
What happens if you wait too long? Waiting past 12 months increases allergy risk. The immune system learns better when babies are younger.
Think of it like learning a language; babies’ immune systems are like super-learners who adapt faster when they’re young! This approach completely alters modern pediatric allergy prevention strategies.
How to Know When Your Baby Is Ready for Solid Foods?
The American Academy of Pediatrics recommends introducing allergenic foods between 4-6 months, coinciding with solid food introduction. This timing allows the immune system to develop tolerance, potentially preventing future food allergies.
Most babies are ready for solids around 6 months, though readiness varies by child.
Key signs include sitting with support, maintaining steady head control, and showing food interest by watching others eat or reaching for plates.
Babies should demonstrate the ability to bring food to their mouths independently.
The disappearance of the tongue-thrust reflex is crucial, babies should no longer automatically push food out with their tongues and should be able to swallow rather than spit food back out.
Wait for multiple readiness signs before beginning solids, and always consult your pediatrician first.
Common Allergens to Introduce First
Introducing allergenic foods early helps reduce the risk of developing food allergies late, understanding which allergens to prioritize and why can help parents make informed decisions about their baby’s diet.
| Allergen | Priority Level | Why Important | Introduction Tips |
|---|---|---|---|
| Peanuts | Highest | Reduces allergy risk by up to 80% | Start with peanut butter mixed in purees |
| Eggs | Highest | Easy to prepare, common allergen | Begin with well-cooked scrambled eggs |
| Cow’s Milk | High | Builds tolerance, provides nutrients | Use in yogurt or cheese, not as a drink |
| Wheat | High | Contains gluten proteins | Introduce through baby cereals |
| Soy | Medium | Found in many processed foods | Use soy-based products sparingly |
| Fish | Medium | Rich in nutrients and proteins | Start with mild white fish |
| Sesame | Medium | Recently added to major allergen list | Use tahini or sesame-containing foods |
| Tree Nuts | Medium | Include multiple nut varieties | Ground nuts mixed into other foods |
NOTE: Babies with family allergy history, eczema, or other risk factors need modified approaches and medical supervision. Consult your pediatrician or allergist before starting allergen introduction for high-risk babies.
Sample Schedule for The First 3 Months of Solids
A structured allergen introduction schedule ensures systematic exposure while prioritizing safety, providing a practical three-month framework that should be customized to your baby’s individual pace and tolerance levels.
Month 1: Foundation Allergens
- Week 1: Introduce eggs (start with well-cooked egg yolk mixed into baby cereal)
- Week 2: Add wheat (baby oat or wheat cereal)
- Week 3: Introduce peanuts (smooth peanut butter thinned with breast milk or water)
- Week 4: Try tree nuts (almond butter or cashew butter, properly thinned)
Month 2: Expanding the Palate
- Week 5: Introduce dairy (plain whole milk yogurt)
- Week 6: Add soy products (silken tofu, mashed)
- Week 7: Introduce fish (well-cooked, flaked salmon or cod)
- Week 8: Try shellfish (finely chopped, well-cooked shrimp)
Month 3: Completing the Major Allergens
- Week 9: Introduce sesame (tahini thinned with water or breast milk)
- Weeks 10-12: Rotate through previously introduced allergens while adding variety and new textures
Progressive Portion Guidelines: Start with ¼ teaspoon of each new allergen, gradually increasing to ½ teaspoon, then 1 full teaspoon as your baby tolerates and accepts each food. Maintain 2-3 day gaps between introducing completely new allergens to monitor for any reactions.
Important Reminders: Always introduce new allergens when your baby is alert and healthy, preferably early in the day for monitoring, while keeping a detailed food diary and adapting the schedule to your baby’s individual pace and preferences.
Recognizing and Responding to Allergic Reactions
Knowing how to identify and respond to allergic reactions can protect babies during food introduction. Quick recognition and proper response help ensure safety while building food tolerance.
| SYMPTOM CATEGORY | WHAT TO LOOK FOR | ACTION REQUIRED |
|---|---|---|
| Skin Reactions | Rashes, hives, red patches around the mouth, swelling of the face or lips | Stop feeding, clean the area, take photos, and monitor closely |
| Digestive Issues | Vomiting, diarrhea, excessive drooling, refusal to swallow | Remove food immediately, offer water if mild, and contact a doctor |
| Respiratory Problems | Difficulty breathing, wheezing, persistent cough, runny nose | Call emergency services immediately, and keep the baby upright |
| Behavior Changes | Unusual fussiness, extreme lethargy, loss of consciousness | Stop all feeding, assess other symptoms, and seek medical help |
| Emergency Signs | Any breathing difficulty, widespread reactions, or multiple symptoms | Call 911, administer epinephrine if available, and stay calm |
Emergency Preparedness Checklist:
- Keep emergency contacts readily available
- Learn severe reaction warning signs before starting solids
- Create a written action plan for all caregivers
- Discuss emergency medications with the pediatrician
- Consider taking infant CPR classes for additional safety
Final Thoughts
Are you staring at that jar of peanut butter, wondering if it’s safe? Every parent feels this way! Food allergies worry most parents, but here’s exciting news: Early allergen introduction might actually protect your baby.
Remember when doctors said, “wait until age three”? Those days are gone! Research shows introducing allergens at 4-6 months helps your baby’s immune system accept these foods instead of rejecting them.
Think of it like teaching a new language; the sooner you start, the better. This guide alters confusing medical advice into simple steps you can take today.

Which Allergens Should I Introduce First?
There’s no specific order required, but many parents start with eggs, then peanuts, followed by dairy, wheat, and other major allergens. Introduce one new allergen every 3-5 days.
How Much of an Allergenic Food Should I Give My Baby Initially?
