Earlier is better: current AAP and CDC guidance says offer peanut and well-cooked egg once your baby shows readiness — most babies start at home. The exception: severe eczema or a known egg allergy means clinician-guided introduction first.
📋 TL;DR — if you read nothing else
- Do not delay. AAP (2025), CDC (2026), and NIAID support offering peanut and egg once readiness appears — routine delay raises allergy risk.
- Know your track: severe eczema or diagnosed egg allergy → clinician guidance before starting (often 4–6 months). Otherwise → home introduction at readiness.
- Safe forms: thinned smooth nut butter mixed into puree; fully cooked egg mashed small. Never whole nuts, spoonful globs, or runny egg for young babies.
- Reaction plan: hives, swelling, or repeated vomiting → call your pediatrician same day. Breathing trouble, throat swelling, or collapse → call emergency services immediately.
Quick answer: Babies are usually ready to try solids around 6 months, and evidence-supported guidance now encourages offering common allergens such as peanut and well-cooked egg once readiness signs appear. Most infants can try these foods at home. Infants with severe eczema or a known egg allergy should get clinician guidance first.
Why This Matters
Recent guidance from the American Academy of Pediatrics (AAP, 2025), the CDC (2026), and NIAID supports introducing common allergenic foods when an infant is developmentally ready rather than routinely delaying them. This approach aims to reduce the chance of developing food allergy at the population level, while clinical decisions for individual infants should stay personalized.
When to start: Babies are typically ready for complementary foods around 6 months. Look for steady head control, sitting with support, and interest in foods. The CDC recommends introduction at about 6 months when these signs are present — not before 4 months — with no required food order. Most families do not need to delay peanut or egg beyond these readiness cues; discuss timing with your pediatrician if you have concerns.
Risk Categories: Who Starts Where
| Risk level | Typical criteria | Suggested next step (general) |
|---|---|---|
| High risk | Severe eczema and/or diagnosed egg allergy | Discuss with your pediatric clinician early: NIAID suggests clinician-guided evaluation and consideration of testing or supervised introduction in early infancy (often 4–6 months). |
| Moderate risk | Mild to moderate eczema | Home introduction at readiness is generally reasonable; ask your pediatrician if you want reassurance. |
| Low risk | No eczema, no food allergy | Offer age-appropriate forms of peanut and well-cooked egg when starting other solids. |
This table summarizes guideline-based pathways, not a protocol — testing and supervised feeding decisions are individualized. After any prior allergic reaction to any food, seek pediatric or allergy evaluation before introducing other allergens.
How to Introduce Allergenic Foods Safely
- Pick the right moment. Your baby should be well — no fever or recent vomiting — and you can watch closely.
- Use a safe texture: smooth thinned paste rather than thick sticky spoonfuls; fully cooked egg mashed small rather than runny.
- Start small and observe. Reactions, when they occur, begin within minutes but can appear later. The CDC recommends single new foods in sequence so a cause can be identified.
- If the first taste goes well, keep offering age-appropriate forms as part of regular feeding; discuss patterns with your pediatrician.
Safe and Unsafe Forms
Safe forms (age- and development-dependent)
- Smooth nut butters diluted or incorporated into purees or soft foods to avoid choking risk.
- Commercial peanut puffs or fortified peanut snack products designed for infants (follow package guidance and modify for age and development).
- Well-cooked whole egg — yolks and whites fully set — mashed or cut into small, soft pieces.
Unsafe forms for infants and toddlers
Whole nuts or large pieces that are choking hazards, thick globs of sticky nut butter served on a spoon or straight from the jar, and raw or undercooked (runny) egg preparations for young infants.
Choking safety and feeding tips
Follow CDC and AAP guidance: seat baby upright, match texture to chewing skills, and avoid common choking hazards — whole grapes, hard raw vegetables, whole nuts, large meat pieces, thick sticky lumps. Our guides:

Recognizing Allergic Reactions: When to Seek Care
Mild to moderate signs — prompt contact with your pediatrician
- Hives or widespread raised rash.
- Noticeable swelling of lips or eyes (not only mild redness).
- Repeated vomiting clearly associated with the food.
- Also arrange clinical follow-up for concerns about persistent eczema, growth, or feeding safety.
Severe signs — call local emergency services immediately
- Any breathing difficulty (wheezing, noisy breathing, difficulty breathing).
- Swelling of the tongue or throat, trouble swallowing, hoarse voice.
- Pale, floppy, or unresponsive child; sudden collapse.
- Repeated severe vomiting with difficulty breathing.
If you suspect a severe allergic reaction, call your local emergency number without delay. If trained and equipped to do so, caregivers may administer an epinephrine auto-injector per their clinician’s instructions. For certified first-aid instruction for infants, see the British Red Cross guidance on choking in babies.
Testing, Siblings, and Family History
- A sibling’s food allergy does not automatically require testing before introduction — family history is one factor among many. Testing is usually recommended only for higher-risk infants (severe eczema or existing food allergy). Discuss concerns with your pediatrician.
How Evidence and Guidelines Are Used Here
- The AAP (2025) and CDC (2026) advise offering allergenic foods like peanut and egg once the infant is developmentally ready, and do not support routine delay.
- NIAID applies a risk-stratified approach: severe eczema and/or egg allergy may warrant clinician-guided evaluation before peanut, with early supervised introduction considered.
- These are population-level recommendations; they do not replace individualized clinical assessment.
👩⚕️ Doctor’s Take
The old advice — wait until age one — is gone: every major body now says introduce peanut and egg early, around the time solids start, because delay works against you. The one branch point is eczema severity. Severe eczema or a confirmed egg allergy? Come to me first; we may want testing or a supervised first dose around 4–6 months. Mild eczema or none? A thin smear of peanut butter stirred into puree and a fully cooked mashed egg at home, on a calm day while you watch, is the right move. Whichever track you are on: first taste is a small taste, single foods in sequence, and everything fully cooked — no runny egg, no globs, no whole nuts.
The Bottom Line
- Offer peanut and well-cooked egg once readiness signs appear — do not routinely delay.
- Severe eczema or egg allergy → clinician-guided plan first; everyone else → home introduction is generally fine.
- Thinned spreads and fully cooked egg only; watch closely; single new foods in sequence.
