Children & Food Allergies
Last reviewed: March 2026
How Common Are Food Allergies in Children?
Food allergies affect approximately 1 in 13 children in the United States, which translates to roughly two students in every classroom. According to a landmark 2019 study published in the journal Pediatrics, an estimated 5.6 million children under age 18 have food allergies, and nearly 40 percent of those children have experienced a severe allergic reaction. The prevalence of food allergies in children has increased significantly over the past two decades, though researchers have not yet determined a definitive cause. The most common food allergens in children are milk, egg, peanut, tree nuts, wheat, soy, fish, shellfish, and sesame. While some childhood allergies, particularly milk, egg, wheat, and soy, are frequently outgrown, allergies to peanuts, tree nuts, fish, and shellfish tend to persist into adulthood. Understanding the scope of childhood food allergies is essential for parents, educators, and caregivers. These are not rare conditions, and the consequences of an unmanaged reaction can be life-threatening. Every child with a diagnosed food allergy should have a written emergency action plan, prescribed epinephrine auto-injectors, and a network of informed adults who know how to respond in an emergency.
Diagnosis in Infants and Toddlers
Diagnosing food allergies in infants and toddlers presents unique challenges because very young children cannot articulate their symptoms. Parents and caregivers must watch for signs that include hives, facial swelling, vomiting, diarrhea, excessive fussiness after feeding, and eczema that does not respond to standard treatment. If a parent suspects a food allergy, the child should be evaluated by a board-certified allergist, not diagnosed through at-home tests or elimination diets alone. The allergist will typically perform skin prick testing and measure allergen-specific IgE levels through blood tests. In some cases, an oral food challenge, the gold standard for diagnosis, may be conducted under medical supervision. The NIAID guidelines, updated in 2017, also recommend early introduction of peanut-containing foods for infants at high risk of peanut allergy (those with severe eczema or egg allergy). The LEAP study demonstrated that early introduction of peanut between 4 and 6 months of age reduced the risk of developing peanut allergy by approximately 80 percent. This finding fundamentally changed pediatric allergy guidance and highlights the importance of working with an allergist before and during the introduction of common allergens in high-risk infants.
Teaching Young Children About Their Allergies
Age-appropriate allergy education is one of the most important investments parents can make in their child's long-term safety. Children as young as two or three can begin learning the basics: certain foods can make them sick, they should only eat food from trusted adults, and they need to tell a grown-up if they feel "funny" or sick after eating. Use simple, consistent language. Phrases like "You are allergic to peanuts. Peanuts are not safe for your body" are concrete and easy for toddlers to understand. Avoid language that frames allergens as "bad" or "poison," which can create unnecessary fear and anxiety. As children reach preschool age (3 to 5), they can learn to recognize the physical appearance of their allergens and understand not to share food with friends. Picture books about food allergies can be helpful tools at this stage. By kindergarten and first grade, children can begin learning to read simple labels and ask "Is this safe for me?" before accepting any food. Between ages 7 and 10, children should progressively learn to read ingredient labels themselves, politely decline unsafe food, and understand the basics of their emergency action plan. The goal is gradual independence, building skills year by year so that by adolescence, the child can confidently manage most allergy situations on their own.
School Management: 504 Plans, IEPs, and Nurse Communication
Schools are one of the highest-risk environments for children with food allergies because parents are not present to monitor food exposure. In the United States, children with food allergies may qualify for a Section 504 plan under the Rehabilitation Act of 1973, which requires schools to provide reasonable accommodations for students with disabilities, including life-threatening food allergies. A 504 plan can mandate allergen-free lunch tables, staff training on epinephrine administration, restriction of allergens in the classroom, and protocols for field trips and parties. Some children with food allergies that affect their ability to learn (for example, through anxiety or frequent absences) may also qualify for an Individualized Education Program (IEP) under the Individuals with Disabilities Education Act. To establish a 504 plan, parents should request a meeting with the school administration, provide medical documentation from the child's allergist, and work collaboratively with the school nurse, teacher, and principal to develop a comprehensive plan. The school nurse is often the linchpin of allergy safety at school. Maintain a strong relationship with the nurse, provide them with updated emergency action plans and medications at the start of each school year, and ensure that backup epinephrine is stored in accessible locations. FARE offers free downloadable school forms and templates that can help structure these conversations.
Birthday Parties, Playdates, and Social Events
Social events are where food allergy management gets most emotionally complex for children and parents alike. Birthday parties, in particular, can feel like minefields. Cakes, cupcakes, candy, and pizza are staples of children's parties, and most contain one or more of the top allergens. Parents of allergic children should communicate with the host family well before the event. Provide clear, specific information about your child's allergens and the severity of potential reactions. Offer to send a safe treat for your child so they can participate without feeling excluded. Some parents choose to send a "stash" of allergy-safe cupcakes or cookies to the freezer of close friends and frequent hosts so a safe option is always available. For playdates, establish clear ground rules with the other family: no shared snacks, hand-washing before and after eating, and awareness of which foods are off-limits. Provide a written summary of your child's allergens and emergency plan. As your child gets older, teach them to advocate for themselves at events, politely declining food and explaining their allergy if needed. Halloween presents its own challenges, as most popular candy contains common allergens. The Teal Pumpkin Project, sponsored by FARE, encourages households to offer non-food treats alongside candy, making trick-or-treating inclusive for allergic children.
Camps, Extracurriculars, and Caregiver Training
Summer camps, sports teams, scouting troops, and after-school programs all introduce new adults and environments into your child's world, and each requires allergy preparation. When evaluating camps, ask specific questions: Does the camp have a nurse or medical staff on site? Are they trained in epinephrine administration? What is the camp's food allergy policy? Are allergens restricted in dining halls? Several camps in the United States specialize in serving children with food allergies, including Camp Blue Spruce and other FARE-affiliated programs. For extracurricular activities, meet with coaches and troop leaders before the season begins to discuss your child's allergy, share the emergency action plan, and provide epinephrine. Babysitters and caregivers who watch your child at home need thorough training. Walk them through the emergency action plan step by step. Have them practice using an epinephrine auto-injector trainer device. Show them where medications are stored, how to read labels, and which snacks in the house are safe. Leave written instructions and ensure they have your phone number, the allergist's number, and the address of the nearest emergency room. Never assume that a caregiver understands food allergies just because they are experienced with children.
Bullying, Emotional Impact, and Sibling Dynamics
Children with food allergies face a disproportionately high rate of bullying. A study published in the journal Pediatrics found that nearly one-third of children with food allergies reported being bullied specifically because of their allergies, with incidents including having allergens thrown at them, being taunted with allergenic foods, and being deliberately excluded from social activities. This type of bullying is not merely unkind; it is physically dangerous. Parents should talk openly with their children about bullying, encourage them to report incidents to trusted adults, and work with school administrators to enforce anti-bullying policies that specifically address food allergy harassment. The emotional toll of living with food allergies extends beyond bullying. Many children with food allergies experience anxiety around eating, social isolation, and feelings of being different from their peers. These emotions are valid and should be acknowledged, not minimized. If your child shows signs of persistent anxiety, withdrawal, or changes in behavior around food or social situations, consider consulting a mental health professional who understands the unique pressures of living with food allergies. Siblings also feel the impact. Non-allergic siblings may feel resentful about dietary restrictions in the home, receive less attention, or struggle with their own anxiety about their sibling's health. Open family conversations about how allergies affect everyone, and making sure each child feels valued, can help maintain healthy sibling relationships.
Adolescent Risk-Taking and Building Independence
Adolescence is statistically the most dangerous period for people with food allergies. Teens and young adults account for a disproportionate number of fatal and near-fatal anaphylaxis events. The reasons are well documented: adolescents take more risks, are less likely to carry their epinephrine, may feel embarrassed about their allergies in social settings, and are more likely to eat unfamiliar foods to fit in with peers. A study in the Journal of Allergy and Clinical Immunology found that fewer than half of adolescents with food allergies consistently carry their epinephrine auto-injectors. Addressing this risk requires a balance of education and empathy. Lecturing teens about danger rarely changes behavior. Instead, involve them in their own allergy management decisions, let them take ownership of reading labels and choosing restaurants, and have honest conversations about real-world scenarios, such as what to do when someone at a party offers food of unknown ingredients. Discuss the specific risks of alcohol, which can lower inhibitions and impair the ability to recognize early symptoms of a reaction. Help them develop scripts for social situations: "I have a serious allergy, so I brought my own food" is simple, confident, and effective. The transition from parent-managed to self-managed allergy care should happen gradually throughout adolescence, with the goal of full independence by the time the young person leaves for college.
When Allergies Are Outgrown
One of the most common questions parents ask is whether their child will outgrow their food allergies. The answer depends heavily on the specific allergen. Research shows that approximately 80 percent of children with milk allergies and about 70 percent of children with egg allergies will outgrow them by age 16. Wheat and soy allergies are also frequently outgrown during childhood. However, peanut allergy is outgrown by only about 20 percent of children, and tree nut, fish, and shellfish allergies persist in the vast majority of cases. The only way to confirm that a child has outgrown an allergy is through an oral food challenge (OFC) conducted under the supervision of a board-certified allergist. This involves the child consuming gradually increasing amounts of the allergen in a controlled medical setting while being monitored for reactions. Parents should never test whether a child has outgrown an allergy at home, as the risk of a severe reaction is real. Allergists typically recommend periodic retesting, often every one to two years, to track whether allergen-specific IgE levels are trending downward, which may indicate that the child is developing tolerance. If an OFC is successful, the allergist will provide guidance on incorporating the food into the child's diet to maintain tolerance.
Supporting Your Child's Confidence and Quality of Life
Living with food allergies does not have to define a child's identity or limit their experiences. With proper planning, education, and support, children with food allergies can participate fully in school, sports, travel, friendships, and every other aspect of childhood. The parent's attitude matters enormously. Children take emotional cues from their parents, so modeling calm confidence rather than visible fear teaches the child that their allergy is manageable. Celebrate your child's growing independence in allergy management. Praise them when they read a label, speak up at a restaurant, or decline an unsafe food. Connect them with other children who have food allergies through support groups, FARE walks, or online communities, so they see that they are not alone. Focus on all the foods they can eat rather than dwelling on what is restricted. Involve them in cooking and meal planning, which builds both skills and a positive relationship with food. As your child grows, help them understand that their allergy is one part of who they are, not the whole story. With the right foundation, children with food allergies grow into capable, confident adults who navigate the world safely and fully.
