About Early Introduction

For many, “early introduction” is a new term. The National Institutes of Health (NIH) recently updated their guidelines on introducing babies to potentially allergenic foods, recommending to start early introduction as early as four months old. This change was inspired by the findings of the landmark LEAP Study, which saw a drastic reduction in the likelihood of developing a peanut allergy after early and consistent exposure to peanut protein.


“Early introduction” means feeding a potentially allergenic food, such as peanut, early on and consistently during your baby’s immune system development. In more simple terms: early and often! Click the button for a crash course in early peanut introduction.
