This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

If a few first foods have gone down without fuss, peanut is this week or next. Here is the whole plan, slowly.

## Heart

The 2017 US guidelines sort babies into three groups ([NIAID](https://www.niaid.nih.gov/sites/default/files/peanut-allergy-prevention-guidelines-parent-summary.pdf)). Severe eczema, egg allergy, or both: peanut as early as 4 to 6 months, after checking with your pediatrician, who may test or refer first; if that's your baby, you've had this conversation already. Mild to moderate eczema: peanut around 6 months. No eczema or food allergy: peanut freely at home, along with other solids ([NIAID](https://www.niaid.nih.gov/sites/default/files/peanut-allergy-prevention-guidelines-parent-summary.pdf)). A 2021 consensus from US and Canadian allergy societies says the same for both peanut and egg: around 6 months, not before 4, with no screening test required ([Fleischer et al., 2021](https://pubmed.ncbi.nlm.nih.gov/33250376/)). If your pediatrician hasn't brought it up, ask.

## Head

The reason the advice is firm is one trial. In LEAP, 640 babies 4 to 11 months old with severe eczema, egg allergy, or both were randomly assigned to eat peanut regularly or avoid it until age 5. Among the 530 whose skin tests were negative at the start, 13.7% of avoiders had peanut allergy at age 5, versus 1.9% of eaters ([Du Toit et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25705822/)). A meta-analysis rated the evidence for early egg and early peanut as moderate certainty ([Ierodiakonou et al., 2016](https://pubmed.ncbi.nlm.nih.gov/27654604/)).

## Body

Start after a few first foods ([NIAID](https://www.niaid.nih.gov/sites/default/files/peanut-allergy-prevention-guidelines-parent-summary.pdf)). The recipe: thin 2 teaspoons of smooth peanut butter with 2 to 3 teaspoons of hot water and let it cool, or stir it into a puree your baby already eats ([NIAID](https://www.niaid.nih.gov/sites/default/files/addendum_guidelines_peanut_appx_d.pdf)). NIAID's home-feeding steps, written for higher-risk babies whose tests were reassuring, are a good habit for any baby: feed at home on a day your baby is well, offer a small taste, wait 10 minutes, give the rest, and watch for 2 hours ([NIAID](https://www.niaid.nih.gov/sites/default/files/addendum_guidelines_peanut_appx_d.pdf)). Egg comes on another day: about a third of a well-cooked egg, mashed ([AAP](https://www.healthychildren.org/English/healthy-living/nutrition/Pages/when-to-introduce-egg-peanut-butter-and-other-common-food-allergens-to-your-baby-food-allergy-prevention-tips.aspx)). Never whole nuts or thick globs of nut butter ([AAP](https://www.healthychildren.org/English/health-issues/injuries-emergencies/Pages/Choking-Prevention.aspx)).

## Try today

### Peanut and egg, early and often

- **Time:** A few minutes, 3 or more times a week once started
- **From the guide:** [Peanut and egg, early and often](https://chorevia.com/learn/6-months#peanut-and-egg-early-and-often)

1. If your baby has severe eczema or an egg allergy, talk to your pediatrician before starting ([NIAID](https://www.niaid.nih.gov/sites/default/files/peanut-allergy-prevention-guidelines-parent-summary.pdf)).
2. Thin 2 teaspoons of smooth peanut butter with 2 to 3 teaspoons of hot water and let it cool ([NIAID](https://www.niaid.nih.gov/sites/default/files/addendum_guidelines_peanut_appx_d.pdf)).
3. With your baby upright and buckled, offer a small taste, wait 10 minutes, then offer the rest at their usual pace, and watch for 2 hours ([NIAID](https://www.niaid.nih.gov/sites/default/files/addendum_guidelines_peanut_appx_d.pdf)).
4. On another day, offer about a third of a well-cooked egg, mashed ([AAP](https://www.healthychildren.org/English/healthy-living/nutrition/Pages/when-to-introduce-egg-peanut-butter-and-other-common-food-allergens-to-your-baby-food-allergy-prevention-tips.aspx)).

**Make it work:** Keep both in the weekly rotation once they're in. Never offer whole nuts or thick globs of nut butter ([AAP](https://www.healthychildren.org/English/health-issues/injuries-emergencies/Pages/Choking-Prevention.aspx)).

## Watch for

- **Normal:** a face, a shudder, and a second open mouth; a grimace isn't a verdict ([Forestell & Mennella, 2007](https://pubmed.ncbi.nlm.nih.gov/18055673/)). **Call your pediatrician right away** for mild signs in the 2 hours after: a new rash or a few hives around the mouth or face, and hold the food until you've talked ([NIAID](https://www.niaid.nih.gov/sites/default/files/addendum_guidelines_peanut_appx_d.pdf); [AAP](https://www.healthychildren.org/English/healthy-living/nutrition/Pages/when-to-introduce-egg-peanut-butter-and-other-common-food-allergens-to-your-baby-food-allergy-prevention-tips.aspx)).
- **Normal:** turning away after a taste or two; stop, and try another time ([AAP](https://www.healthychildren.org/English/ages-stages/baby/feeding-nutrition/Pages/Starting-Solid-Foods.aspx)). **Call 911** for lip, face, or tongue swelling, vomiting, widespread hives, trouble breathing, wheezing, repeated coughing, pale or blue skin, or sudden tiredness or floppiness ([NIAID](https://www.niaid.nih.gov/sites/default/files/addendum_guidelines_peanut_appx_d.pdf)).
- **Normal:** a long nap after the 2-hour watch. **Call 911** if your baby can't be woken up, isn't moving, or is very weak ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Fever)).

## For you

The first taste is scary for a reason, and the plan is what makes it smaller. You have the list, a well day, home, and a clock ([NIAID](https://www.niaid.nih.gov/sites/default/files/addendum_guidelines_peanut_appx_d.pdf)), and the thing you're afraid of is the thing the trial showed the spoon prevents: 13.7% versus 1.9% in the highest-risk babies ([Du Toit et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25705822/)). Most babies need no test first ([Fleischer et al., 2021](https://pubmed.ncbi.nlm.nih.gov/33250376/)).

If you're the partner: be home for this one. One of you watches the clock, one watches the baby, and neither of you watches a phone.
