Questions?
We have answers.

Is my baby ready at 4 months?

Leading guidelines support introducing common allergens once your baby is at least 4 months old. Stage 1+2 mixes into breastmilk or formula, so your baby doesn’t need to be on solids to start. If your baby has severe eczema or a known allergy, check with your pediatrician first.

Which stage should I start with?

Almost every baby starts with Stage 1+2. If you’ve finished Stage 1+2 and want another month of peanut, egg and milk before expanding, that’s Stage 2. If your baby already eats all three regularly, go to Stage 3.

My baby is older than 6 months - is it too late?

No. Guidelines recommend introducing allergens around 6 months and keeping them in the diet - if you haven’t started, now is a good time.

Can’t I just do this myself with peanut butter?

You can. The plan takes the measuring, pacing and remembering off your plate: pre-measured amounts, one allergen at a time, one packet a day for months.

Research-backed

What the research says

The landmark studies and guidelines behind every packet.

  • The LEAP StudyNew England Journal of Medicine, 2015

    640 infants at high risk of peanut allergy either ate or avoided peanut from 4–11 months until age 5. Early, regular peanut consumption was associated with a markedly lower rate of peanut allergy - the study behind today’s guidelines.

  • NIAID (National Institutes of Health)Peanut Introduction Guidelines, 2017

    US guidelines recommend introducing peanut-containing foods as early as 4–6 months for infants at highest risk, around 6 months for those with mild-to-moderate eczema, and freely for infants without eczema or food allergy.

    Read the study → (opens in a new tab)
  • USDA & HHSDietary Guidelines for Americans, 2020–2025

    The first Dietary Guidelines to cover infants: introduce potentially allergenic foods alongside other complementary foods - there is no evidence that delaying them helps prevent food allergy.

    Read the study → (opens in a new tab)
  • American Academy of PediatricsClinical Report, 2019

    The AAP’s review found no evidence that delaying allergenic foods helps prevent allergy, and concluded that early peanut introduction may help reduce the risk of peanut allergy in high-risk infants.
