Baby Ledger AIEgg is one of the two allergens most parents are told to introduce early, alongside peanut, and it is also one of the easier ones to serve because it cooks into so many familiar baby foods. It can still feel nerve-wracking to offer it the first time. This guide walks through when babies are usually ready, why current guidance points toward introducing egg early and keeping it in the rotation, what a well-cooked first serving can look like by age, what a reaction can look like, and how egg hides on labels under names you would never guess. It is a starting point for the conversation with your pediatrician, not a replacement for it.
Who should talk to the doctor first
Before we go any further, the most important part of this page: not every baby should start egg at home on their own schedule. The NIAID 2017 Addendum Guidelines (current US guidance for early peanut introduction, endorsed by the American Academy of Pediatrics and not superseded as of 2026) define the infants at highest risk of food allergy as those with severe eczema and/or an existing egg allergy. That guidance recommends those high-risk infants be evaluated by a doctor before peanut introduction, with some having a first exposure in a supervised setting - and clinicians commonly extend the same caution to introducing egg. A strong family history of food allergy is a reason to check with your pediatrician too, though on its own it is not part of the NIAID high-risk definition. An article cannot tell you which group your baby is in. If any of that describes your child, talk to your pediatrician or allergist before offering egg. If your baby has already reacted to egg, do not re-introduce it at home at all; that is an allergist's job.
When are babies usually ready for egg?
Most babies are developmentally ready for solid food around 6 months, and the CDC advises not before about 4 months. Readiness signs generally include sitting up with little or no support and steady head control, showing interest in food, having lost the early reflex that pushes food back out of the mouth, and being able to move food to the back of the mouth and swallow.
Current pediatric and allergy guidance supports introducing common allergens like egg early, once a baby has tolerated a few first foods, rather than holding them off. The specific timing for your child should be confirmed with your pediatrician, especially if your baby is in one of the higher-risk groups above.
Why egg is an "introduce early" food
The shift toward early, regular egg came from research, and it is worth knowing what the studies actually found so you can weigh it with your doctor.
- The EAT study (NEJM, 2016) introduced several allergenic foods, including cooked egg, to breastfed infants starting around 3 months. Early introduction was found to be safe. In the analysis of families who were able to stick with the regimen, early egg was associated with a lower rate of egg allergy, though the study's main intention-to-treat analysis did not reach statistical significance, partly because the regimen was hard to keep up.
- The PETIT trial (The Lancet, 2017) was a trial in high-risk infants who already had eczema. Under the trial's medical protocol, alongside active eczema treatment, infants were given tiny measured amounts of heated egg (the study used 50 mg of heated egg powder per day from 6 to 9 months, then 250 mg per day until 12 months). Egg allergy occurred in about 8 percent of the egg group versus about 38 percent of the placebo group - roughly a 79 percent lower rate. Importantly, this was done under medical supervision with eczema being treated at the same time, not as a do-it-yourself plan.
The takeaway most clinicians draw from this body of work is that introducing well-cooked egg early and keeping it in the diet is generally reasonable for many babies, while the highest-risk babies need a doctor involved first. Your pediatrician is the right person to apply this to your child. (For the parallel evidence on peanut, see our guide to introducing peanut, and for the overall order and spacing, our allergen introduction schedule.)
Cook it fully - and a word on "baked egg" and the egg ladder
A few points where the form of the egg matters:
- Always cook egg thoroughly. Published pediatric guidance is to serve fully cooked egg to babies, never raw or runny, because undercooked egg carries a risk of salmonella and is not appropriate for infants. Hard-cooked yolk, fully scrambled egg, and egg baked into food are all cooked forms.
- "Baked egg first" means something specific. You may read that egg is less allergenic when baked into muffins or other foods, and allergy research supports that extensively baked egg is tolerated by a large share of egg-allergic children (published allergy sources put this in the range of roughly 70 to 80 percent). But that finding is about children who already have egg allergy, and moving them along a "baked egg then less-cooked egg" progression is an egg ladder - a real approach in allergist practice that is medically supervised, not a home experiment. For a typical baby with no prior reaction, you are simply offering well-cooked egg; you are not running a ladder.
- Never use the ladder or baked-egg tolerance idea to test a baby who has reacted. That decision belongs to an allergist.
Serving forms by age
The forms below are common starting points that parents and pediatricians use for conversation, not a prescription. Amount, texture, and timing for your child should be confirmed with your pediatrician, and every serving should be a size and consistency your baby can handle safely, since choking risk is managed by texture, not by allergy status.
| Baby's stage | A common well-cooked egg form | Notes |
|---|---|---|
| Around 6 months (starting solids) | Hard-cooked egg yolk mashed into a familiar puree (breast milk, formula, or a fruit/veg your baby already eats); or fully scrambled egg mashed very soft | Introduce as a single new food so a reaction can be traced. Confirm the starting amount with your pediatrician. |
| ~7-9 months | Soft scrambled egg in small soft pieces; well-cooked omelet cut into strips; egg baked into a soft food | Match texture to your baby's chewing stage. |
| ~9-12+ months | Small soft pieces of well-cooked whole egg; egg in soft baked foods | Keep egg in the rotation once tolerated rather than offering it once and dropping it. |
General guidance describes keeping a tolerated allergen in the diet regularly; the specific cadence for your child is a question for your pediatrician, not a number to pull from a blog.
What an egg reaction can look like
Most first introductions go fine. You watch during the feeding and for a couple of hours afterward so you can act quickly if something happens. Reactions can be mild to moderate or, rarely, severe.
Mild to moderate signs may include:
- A few hives, or redness and swelling around the mouth or on the skin
- An itchy, runny, or congested nose; sneezing
- Mild swelling of the lips or face
- Vomiting or diarrhea
- Fussiness that seems tied to the new food
Severe signs (anaphylaxis) can include:
- Trouble breathing, wheezing, or noisy breathing
- Swelling of the tongue, throat, or lips that affects breathing or swallowing
- Repetitive coughing, a hoarse or weak cry
- Pale or bluish skin, floppiness, or sudden lethargy
- Vomiting combined with breathing changes or skin changes
These are common signs, not diagnostic criteria, and symptoms can vary. If you are uncertain, treat it as a reaction and get help.
When to call the doctor (and when to call 911)
Call 911 (or your local emergency number) right away if you see any sign of a severe reaction: trouble breathing, swelling that affects breathing or swallowing, repetitive coughing with distress, pallor or bluish color, floppiness, or a sudden collapse. If your child has been prescribed epinephrine, use it exactly as your doctor instructed and then call emergency services. Severe reactions can move fast.
Call your pediatrician the same day for milder reactions, such as a handful of hives, vomiting, or facial redness, so you can get guidance before the next serving and find out whether allergy testing makes sense. Do not offer egg again until you have that guidance.
Hidden egg on labels - and the log-and-recheck habit
Egg is one of the major US allergens that must be declared in plain language on packaged food labels, so a product should say "egg" somewhere. But egg-derived ingredients also appear under names you would not connect to breakfast: albumin, ovalbumin, ovomucoid, ovomucin, ovoglobulin, ovotransferrin (also called conalbumin), lysozyme, globulin, livetin, apovitellin, vitellin, ovovitellin, meringue and meringue powder, dried egg solids, egg-derived lecithin, and simplesse. On imported or foreign-language packaging, egg may not be written in English at all. This is where a reaction history and a good record start to matter more than memory.
That is the habit this app is built around. After you introduce a food, you log it in Baby Ledger AI along with any reaction and a timestamp, so the history lives in one place instead of scattered across texts and half-remembered afternoons. Over time you build an allergen profile for your child. The AllerSee™ scanner then lets you scan a product by barcode or photo and cross-check its ingredients against that profile, and it is designed to flag hidden egg under those alternative names, including on imported products where the ingredient database has little to no data. The scanner is a capability, not a guarantee: it is an informational, label-reading aid, not a medical device, and it does not replace reading the full label yourself or your pediatrician's guidance. The allergen cross-check, barcode scanning, and FDA recall check are free and unlimited on every plan; only the AI photo scans and Saurus questions carry a daily limit on Free (2 each per day), because those cost real money each time they run.
Frequently asked questions
At what age can I introduce egg to my baby?
Most babies start solids around 6 months (and not before about 4 months, per the CDC), and egg is commonly worked in once a few first foods are tolerated. Some higher-risk babies should be evaluated first, so confirm timing with your pediatrician before you start.
Do I have to fully cook the egg?
Yes. Published pediatric guidance is to give babies fully cooked egg, never raw or runny, because undercooked egg carries a salmonella risk and is not appropriate for infants.
Yolk or white first, or both?
Egg allergy is more often tied to the white, but both yolk and white are commonly introduced as babies start solids. There is no single required order; whole well-cooked egg is fine for many babies. Confirm the approach for your child with your pediatrician.
Is "baked egg" safer to start with?
Extensively baked egg is less allergenic and is tolerated by many children who already have egg allergy (allergy sources cite roughly 70 to 80 percent), but that is an allergist's assessment. For a baby with no prior reaction you are simply offering well-cooked egg, not running a supervised ladder. Do not use baked egg to test a child who has reacted.
How often should I give egg after introducing it?
General guidance describes keeping a tolerated allergen in the diet regularly rather than introducing it once and dropping it. Your pediatrician can recommend the specific cadence for your child.
What do I do if my baby reacts to egg?
For severe signs (trouble breathing, swelling affecting breathing or swallowing, pallor, floppiness), call 911 immediately and use prescribed epinephrine if you have it. For milder signs (a few hives, vomiting), call your pediatrician the same day and do not offer egg again until you have their guidance. Never re-introduce egg at home after a reaction.
Can I introduce egg with baby-led weaning?
Many families do, as long as the egg is fully cooked and served in a safe, age-appropriate size and texture (for example, soft scrambled egg in small pieces). Choking risk, not allergy risk, is what texture and size manage.
