In severe cases, anaphylaxis can occur, which requires immediate medical attention to prevent serious complications. Another danger of giving your kids peanut butter is the risk of cross-contamination. Many food products, including snacks and baked goods, may contain traces of peanuts or peanut butter, even if they are not listed as ingredients. This can be particularly dangerous for children with peanut allergies, as even small amounts of peanut residue can trigger a reaction. It is essential for parents to carefully read food labels and ask about potential cross-contamination when dining out to minimize the risk of exposure.
