Ready. Set. Food! Stage 1 Mix-ins include 30 packets that can easily be added to breastmilk, bottle or mixed in with infant baby food for the perfect early introduction to allergens. Follow Stage 1 Mix-ins with Stage 2, combination packets with all three top allergens to safely continue and maintain your babys exposure to those allergens for at least 2 months or more. Evidence Based 3-Stage System for Baby Food Allergy Introduction Ready. Set. Food! has developed a research-based, pediatrician-recommended approach to safely, effectively, and gradually introduce infants to some of the highest food allergens. Pediatricians recommend one-at-a-time infant allergy introductions, starting at four months of age, to help support early baby allergy introduction. Our 3 Stage System Mix-in system starts with our Stage 1 Mix-ins, which introduce peanut, egg, and milk and are added to bottles and organic baby foods. These baby food allergy mix-ins come as individual packets that are given over the course of 15 or 30 days. The beginning packets introduce milk, the next packets introduce egg while maintaining exposure to milk, followed by the introduction of peanut while maintaining exposure to milk and egg. Stage 2 Mix-ins are designed to maintain continued exposure to those top 3 allergens, and must be consistently given for at least 2 months. Stage 3 Mix-ins introduce 6 additional top allergens, and can be given to children at 6 months. As your little one continues to grow and eat, we also offer Ready. Set. Food! Baby Oatmeal, for a 6 month old baby and older who has started eating solids, Organic Puffs for an 8 month old or older, and Organic Fruit and Oat Bars for a 12 month old and older. Each product offers increased exposure to the top 8-9 allergens for easy allergen maintenance!
