The allergens found in our Stage 3 Mix-Ins product are the top allergy-causing foods for babies and young children, and represent 90% of food allergies in children. Of the top allergens, peanuts, eggs, and milk alone make up 80% of food allergies in children. That's why those 3 allergens are included in our Stage 1 Mix-Ins and Stage 2 Mix-Ins products. According to the new USDA Guidelines introducing your baby to peanuts, eggs, and milk as early as 4 months of age is important.
