Maintain daily exposure to peanut, egg, and milk (top 3 allergens) for at least 2 months. Pre-measured daily packets. 100% organic real food. No added sugar. Start as early as 4 months of age. The system is both bottle and food-friendly. Some boxes in the current run may not have the USDA Organic seal due supply chain issue of the organic egg whites, but all eggs are still free range!
