The first taste matters less than the next thirty. The weekly peanut target, what the EAT and LEAP trials found about sticking with it, and why your own diet is no shortcut.

A Middle Eastern father spoons peanut-thinned puree to his twenty-seven-week-old buckled in a high chair while the mother makes a tick on a calendar stuck to the fridge, evening kitchen light.

Yesterday was the first taste. Today is the part that does the work: the next one, and the one after that.

Heart

The goal is about 6 to 7 grams of peanut protein a week over 3 or more feedings (NIAID); 2 teaspoons of peanut butter has about 2 grams (NIAID). Keep egg and the other allergens in the diet too, and never serve whole nuts (AAP). That's the arithmetic of this month: not one brave spoonful, but the same thinned peanut butter stirred into a puree a few times a week until it's just another food.

Head

Consistency is the hard part, and the trials say so. The EAT trial randomized 1,303 breastfed 3-month-olds in the UK to start six allergenic foods early or at about 6 months. Allergy developed in 5.6% of the early group and 7.1% of the standard group, a difference that could have been chance; the families who stuck with the plan had less peanut and egg allergy, but many found it hard to keep up (Perkin et al., 2016). In LEAP, the protection held: at age 12, after years of eating peanut or not as they pleased, 15.4% of the original avoiders were allergic, versus 4.4% of the eaters (Du Toit et al., 2024). After the US guidelines changed, peanut allergy diagnoses by age 3 in primary care records fell from 0.79% to 0.45% (Gabryszewski et al., 2025), though a before-and-after comparison can't prove cause.

Body

A parent's diet is no shortcut. In a 2026 trial of 2,137 pregnant people with a family history of allergy, eating lots of eggs and peanuts through pregnancy and early breastfeeding didn't lower babies' egg or peanut allergy at age 1 (7.8% versus 8.4%) (Palmer et al., 2026). What protects your baby is your baby eating the food. The form stays the same every time: thinned peanut butter or peanut stirred into a puree, from a spoon, with your baby upright and buckled; no whole nuts, no thick globs (NIAID; AAP).

  1. The mother's hand drawing a small tick on a fridge calendar with two ticks already in the week, the father and the baby in the buckled high chair reflected in the dark window.

    The three-a-week tally

    Time: 10 seconds per serving

    1. On the calendar, draw a small P on every day your baby eats a peanut serving (NIAID).

    2. Each serving is the usual 2 teaspoons of smooth peanut butter, thinned or stirred into a puree (NIAID).

    3. Look at the week on Sunday: 3 or more marks is the goal (NIAID).

    4. Add an E for egg days, and keep both going (AAP).

    Make it work:

    A week with one mark isn't a failure; it's a week to restart. The EAT families' problem was keeping up, not starting (Perkin et al., 2016).

Watch for

  • Normal

    a reaction-free first taste followed by a reaction-free second; the marks are the plan.

    Call 911

    , on any serving, for lip, face, or tongue swelling, vomiting, widespread hives, wheezing, trouble breathing, pale or blue skin, or sudden floppiness (NIAID).

  • Normal

    squeals and raspberries from the high chair between spoonfuls (CDC).

    Don't wait

    to talk to your pediatrician if your baby doesn't laugh, squeal, or trade sounds with you (CDC; CDC).

  • Normal

    a serving eaten on Tuesday and refused on Friday; stop and try another time (AAP).

    Call your pediatrician right away

    if your baby cries nonstop, cries when touched or moved, or won't move an arm or leg normally (AAP).

For you

The mother sitting on the kitchen floor with her back to the fridge, eating a bowl of her own dinner, the father beside her holding the baby upright on his knee.

You don't have to eat a single peanut. The 2026 trial is the permission slip: eating eggs and peanuts through pregnancy and early breastfeeding didn't lower babies' allergy (Palmer et al., 2026). Eat what you like. What protects the baby is the baby eating the food, 3 or more times a week, from your spoon (NIAID).

The tally is also the thing that lets you stop thinking about it. Three marks and you're done for the week; no marks and you know on Sunday, not at the allergist's.

If you're the partner: the calendar is yours. Draw the P.
