SpoonfulOne makes three products that correlate to a stage of baby's feeding abilities: mix-in powder to be added to purees for babies beginning around 4 to 5 months old, puffs for crawling babies, and oat crackers for toddlers. If consumed consistently, each product provides baby with enough gentle exposure to nine food groups: peanuts, milk, shellfish (shrimp), tree nuts (almonds, cashews, hazelnuts, pecans, pistachios, and walnuts), egg, fish (cod and salmon), grains (oats and wheat), soy, and sesame. These food groups are associated with over 90 percent of food allergies according to the Food and Drug Administration. Exposing baby to small amounts of these foods early and often may reduce the risk of developing a food allergy according to expert panels, including the American Academy of Pediatrics. SpoonfulOne Mix-In Powder ($19) makes it easy to maintain all of the most common food allergens in a baby's diet.
