Elimination diet for toddlers with allergies


Food allergies and intolerances are increasingly common in toddlers, and one of the main diagnostic and management tools is an elimination diet. This is a short-term, structured eating plan designed to identify foods that trigger allergic reactions or sensitivities. Since toddlers are still developing physically and nutritionally, elimination diets must be approached carefully under medical supervision.


What Is an elimination diet?


An elimination diet involves removing certain foods that are suspected allergens or irritants from your child’s diet for a set period (usually 2–6 weeks). After symptoms improve, the foods are reintroduced one at a time to see which ones cause reactions. This helps pinpoint which foods should be permanently avoided.


Common food allergens in toddlers


While any food can cause an allergic reaction, the majority of toddler food allergies are linked to:


  • Milk and dairy products


  • Eggs


  • Peanuts


  • Tree nuts (almonds, cashews, walnuts, etc.)


  • Soy


  • Wheat (gluten-containing grains)


  • Fish and shellfish


    These are often referred to as the “top 8 allergens”, and they account for most childhood allergic reactions.


    Signs that may indicate a food allergy

    Parents may be advised to consider an elimination diet if their toddler shows persistent issues such as:

  • Eczema or skin rashes


  • Chronic diarrhea or constipation


  • Gas, bloating, or stomach pain


  • Vomiting after eating certain foods


  • Frequent respiratory issues (congestion, wheezing) not linked to infections


  • Irritability, poor sleep, or feeding difficulties


    Steps to follow in an elimination diet


    1. Consult a paediatrician or allergist

      Never start on your own—toddlers need balanced nutrition for growth. A specialist can guide food choices and provide safe alternatives.


    2. Plan the elimination phase (2–6 weeks)


      • Remove all suspected allergens completely.


      • Read labels carefully (allergens are often hidden in processed foods).


      • Keep meals simple with whole foods to minimize accidental exposure.


    3. Monitor symptoms

      Track your toddler’s symptoms daily—skin, digestion, behaviour, and breathing. Note improvements or worsening after foods are removed.


    4. Reintroduction phase


      • Add one food back at a time (every 3–5 days).


      • Start with small amounts, then gradually increase.


      • Watch for reactions within 24 -72 hours.


    5. Long-Term management

    Once the trigger food is identified, eliminate it permanently. A dietitian can help ensure your child still gets proper nutrition.


    Nutrition concerns during elimination diets


    Eliminating major foods can put toddlers at risk of nutrient deficiencies. Common concerns include:

  • Calcium and vitamin D: if dairy is removed


  • Protein: if multiple allergens (milk, eggs, nuts) are excluded


  • Iron and B vitamins: if wheat/gluten is eliminated


  • Healthy fats: if nuts or eggs are removed Safe substitutes may include:

  • Fortified dairy alternatives (soy, oat, rice, or almond milk—if tolerated)


  • Lean meats, poultry, and fish (if not allergenic)


  • Lentils, beans, and peas for plant-based protein


  • Fruits, vegetables, and whole grains for fiber and micronutrients


    Safety considerations


  • Never try a broad elimination diet without professional guidance. Severe restrictions can harm growth.

  • Keep emergency medication available if your child has a diagnosed allergy (e.g., epinephrine auto-injector).

  • Don’t delay reintroduction too long. Prolonged avoidance without true allergy confirmation can sometimes increase sensitivity.


When to seek immediate help

If your toddler experiences symptoms like difficulty breathing, swelling of lips/tongue, or hives after eating, this is an anaphylactic emergency—call emergency services right away.


Final thoughts


An elimination diet can be a powerful tool for identifying food allergies or intolerances in toddlers, but it must be done methodically and with medical supervision. The key is balancing safety, accurate identification of triggers, and maintaining proper nutrition for healthy growth.

Eczema and food allergies in toddlers

Eczema and food allergies in toddlers Microsoft Word – Eczema and food allergies in toddlers.docx

Eczema and food allergies in toddlers are closely connected, but they’re not always the same thing. Many parents assume that eczema (atopic dermatitis) is directly caused by food, but the relationship is more complicated. Here’s what you should know:


Understanding eczema in toddlers


  • Chronic skin condition: Eczema causes dry, itchy, inflamed skin. It usually starts in infancy or early childhood.

  • Immune-related: Toddlers with eczema often have an overactive immune system that reacts strongly to irritants and allergens.

  • Genetic factor: A family history of allergies, asthma, or eczema increases risk.


    The link between eczema and food allergies


  • Higher risk: Children with moderate to severe eczema are more likely to develop food allergies.

  • Not always food-related: In most toddlers, eczema flare-ups are triggered by things like dry air, heat, soap, detergents, or infection—not food.

  • Food allergy connection: About 30–40% of children with moderate to severe eczema may also have a food allergy (commonly to cow’s milk, egg, peanuts, wheat, or soy).

  • Skin barrier issue: Eczema damages the skin barrier, making it easier for allergens to “sensitize” the immune system, which can lead to food allergies later on.


    Signs food might be triggering eczema


  • Eczema flare-ups that worsen consistently after eating a certain food.


  • Immediate reactions (hives, swelling, vomiting, wheezing) within minutes to 2 hours of eating.

  • Ongoing, stubborn eczema that doesn’t respond to standard treatment and flares even with good skincare.

    Important: Not every eczema flare is food-related. Random elimination diets can cause nutrition problems in toddlers. Always consult a paediatrician or allergist before removing foods.


    Diagnosing food allergies in toddlers with eczema


  • History & observation: Doctors will check patterns between foods and symptoms.


  • Skin prick test or blood test: These can help detect sensitization but don’t confirm an allergy alone.

  • Oral food challenge: The gold standard, done under medical supervision, to confirm if a food truly triggers a reaction.


    Managing eczema and food allergies


    1. Daily eczema care


      • Use fragrance-free moisturizers multiple times a day.


      • Short, lukewarm baths followed by moisturizer ("soak and seal" method).


      • Avoid scented soaps, bubble baths, and harsh detergents.


      • Dress toddler in cotton clothing, avoid wool.


    2. Medical treatment


      • Paediatricians may prescribe topical steroids or non-steroid creams for flare-ups.


      • Antihistamines can sometimes help with itching.


    3. Allergy management (if diagnosed)


      • Strict avoidance of the confirmed allergen.


      • Emergency plan with an epinephrine auto-injector if the allergy is severe.


      • Nutrition guidance to make sure the child doesn’t miss key nutrients when avoiding certain foods.

    Key Takeaways


  • Most toddler eczema is not directly caused by food, but children with eczema are more likely to have food allergies.

  • Do not start eliminating foods on your own—this can make eczema worse and cause growth issues.

  • If you suspect food is playing a role, keep a food and symptom diary and consult a paediatrician or allergist.

  • The foundation of management is good daily skin care plus medical treatment, with allergy testing and avoidance only if necessary.

Allergy testing for toddlers: food sensitivity and what parents should know


Food allergies and sensitivities in toddlers can be stressful for both the child and their parents. At this stage of life, children are still developing their immune systems, and their reactions to certain foods can vary widely—from mild skin rashes to severe, life-threatening responses.

Understanding the types of tests available, their accuracy, and what steps to take is crucial for proper diagnosis and management.


Food allergy vs. food sensitivity


Before diving into testing, it’s important to understand the distinction:


  • Food allergy: An immune system reaction that occurs shortly after eating a particular food. Even small amounts can trigger symptoms such as hives, swelling, vomiting, breathing difficulty, or anaphylaxis. Common culprits include milk, eggs, peanuts, tree nuts, wheat, soy, fish, and shellfish.

  • Food sensitivity/intolerance: Unlike allergies, sensitivities do not involve the immune system in the same way. They may cause delayed or mild reactions such as stomach upset, bloating, eczema flare-ups, or irritability. For example, lactose intolerance is a sensitivity, not an allergy.


    Signs of food allergies in toddlers


    Symptoms of a food allergy often appear quickly (within minutes to 2 hours). Watch for:


  • Hives or skin rash


  • Swelling of lips, eyes, or face


  • Vomiting or diarrhoea


  • Coughing, wheezing, or difficulty breathing


  • Extreme fussiness or inconsolable crying after eating


    Food sensitivities, however, may take longer to show up and include:

  • Gas, bloating, or stomach pain


  • Loose stools or constipation


  • Eczema flare-ups


  • Sleep disturbances


  • Behavioural changes after eating


Common food allergies in toddlers and their symptoms


Certain foods are responsible for the majority of allergic reactions in children. Here are the most common ones:

  1. Cow’s milk


    • Symptoms: Hives, vomiting, diarrhoea, bloody stools, eczema flare-ups, irritability after feeding.

    • Milk allergy is the most common in infants and toddlers, often appearing within the first year of life. Some children outgrow it by school age.

  2. Eggs


    • Symptoms: Skin reactions (hives, rashes), stomach cramps, vomiting, nasal congestion, or wheezing.

    • Egg allergies usually involve the whites but can also occur with yolks. Many children outgrow this allergy by age 5–6.

  3. Peanuts


    • Symptoms: Hives, facial swelling, difficulty breathing, anaphylaxis in severe cases.


    • Peanut allergies are often long-lasting and can be life-threatening. They require strict avoidance.

  4. Tree nuts (almonds, walnuts, cashews, etc.)


    • Symptoms: Similar to peanuts—rashes, swelling, vomiting, breathing problems, or anaphylaxis.

    • Cross-reactivity is common, meaning if a child is allergic to one nut, they may also react to others.

  5. Soy


    • Symptoms: Hives, runny nose, stomach upset, diarrhoea, and eczema.


    • Often found in processed foods, which makes avoidance tricky. Some children outgrow it.


  6. Wheat


    • Symptoms: Hives, digestive issues, nasal congestion, or in rare cases, anaphylaxis.


    • Must be distinguished from celiac disease, which is an autoimmune condition triggered by gluten.

  7. Fish


    • Symptoms: Hives, swelling, stomach upset, wheezing, or severe reactions.


    • Fish allergies tend to persist into adulthood and may apply to one or multiple species.


  8. Shellfish (shrimp, crab, lobster, etc.)


    • Symptoms: Hives, vomiting, swelling, coughing, and potential anaphylaxis.


    • Typically lifelong, shellfish allergies are among the most severe.


Types of allergy testing for toddlers


  1. Skin prick test (SPT)


    • A small amount of allergen extract is placed on the skin (usually the forearm or back) and lightly pricked.

    • If the toddler is allergic, a raised bump (similar to a mosquito bite) will appear.


    • Pros: Fast results (within 15–20 minutes), widely used, inexpensive.


    • Cons: Can be uncomfortable, may produce false positives, and requires specialist supervision.

  2. Blood test (IgE test / RAST or ImmunoCAP)

    • Measures the level of allergy-related antibodies (IgE) in the blood against specific foods.


    • Pros: No skin pricking, safer for children with severe eczema or asthma, results not affected by antihistamines.

    • Cons: Requires a blood draw, may be less precise, results can take several days.


  3. Oral food challenge (OFC)


    • The toddler is fed the suspected allergen in gradually increasing amounts under close medical supervision.

    • Considered the gold standard for diagnosing food allergies.


    • Pros: Most accurate way to confirm or rule out an allergy.


    • Cons: Risk of severe reactions, only performed in a clinical setting.


  4. At-home sensitivity tests (not recommended)


    • Hair, saliva, or finger-prick blood tests marketed online for food sensitivities are not scientifically validated.

    • These often measure IgG antibodies, which only indicate food exposure, not an allergic reaction.

    • Paediatricians and allergists do not recommend these for diagnosing food issues.


      When to consider testing


      Testing should be discussed with your paediatrician if your toddler shows:


    • Repeated or severe reactions after eating certain foods


    • Persistent eczema that does not improve with treatment


    • Chronic digestive issues linked to meals


    • Family history of severe allergies


      Do not remove multiple foods from your toddler’s diet without medical advice. Restrictive diets at this age can lead to nutrient deficiencies.

      Preparing for a toddler’s allergy test


    • Medical history: Your child’s doctor will ask about reaction timing, food triggers, and family history.

    • Medications: Antihistamines may need to be stopped before a skin prick test. Always ask your doctor.

    • Comfort: For blood draws or skin tests, bring a favourite toy or blanket to ease anxiety.


      Managing food allergies or sensitivities


      If an allergy is confirmed:


    • Avoid the trigger food completely.


    • Learn to read ingredient labels carefully.


    • Ask your paediatrician if you should carry an epinephrine auto-injector (EpiPen).


    • Work with a registered dietitian to ensure your toddler gets balanced nutrition.


      If it’s a sensitivity rather than an allergy:


    • Tolerance levels may vary; some children can handle small amounts.


    • Keep a food diary to track symptoms.


    • Discuss with your paediatrician whether foods should be reduced, avoided, or reintroduced later.


Introducing new foods to toddlers safely


Introducing new foods is an important part of development, but it can be nerve-wracking if you’re worried about allergies. Here are safe practices backed by paediatric guidelines:

  1. Start around 6 months

    • Most babies can begin solids around 6 months. Delaying allergenic foods (like peanuts or eggs) beyond this age does not prevent allergies.

  2. Introduce one food at a time


    • Wait 3–5 days before introducing another new food. This makes it easier to spot reactions.


  3. Start with small amounts


    • Begin with a tiny portion (like a small spoonful) and watch for reactions for at least 2 hours.

  4. Introduce high-risk foods early


    • Research shows that early introduction of peanuts and eggs (around 6–12 months) may actually reduce the risk of developing allergies—especially in high-risk children (those with eczema or existing food allergies).

  5. Avoid whole nuts and choking hazards


    • Serve allergenic foods in safe forms—such as smooth peanut butter thinned with water or mashed egg yolk. Whole nuts and chunky nut butters are choking risks for toddlers.

  6. Know the emergency plan


    • If your child has shown any allergic reaction before, talk with your paediatrician before reintroducing foods.

    • Keep antihistamines handy, and if your doctor prescribes an epinephrine auto-injector, always carry it.


      Key takeaways


    • True food allergies in toddlers are immune-based and can be serious, while food sensitivities cause discomfort but are not life-threatening.

    • Reliable testing includes skin prick tests, blood tests, and oral food challenges under medical supervision.

    • At-home sensitivity kits are not reliable and should not guide dietary changes.

    • The most common toddler food allergies include milk, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish.

    • Always involve a paediatrician or paediatric allergist before testing or eliminating foods.

Introducing allergenic foods to infants

Introducing allergenic foods to infants Microsoft Word – Introducing allergenic foods to infants.docx

Introducing allergenic foods to infants has been one of the most discussed topics in paediatric nutrition over the last decade. Guidelines have shifted significantly as research has shown that delaying introduction may actually increase the risk of developing food allergies, rather than preventing them. Below is an overview of current recommendations and timing guidelines for introducing allergenic foods.


Why timing matters


Food allergies are most often triggered by early childhood exposure to allergens. In the past, parents were advised to delay introducing high-risk foods such as peanuts, eggs, or shellfish. However, large-scale studies (notably the LEAP and EAT trials) demonstrated that early, safe introduction of these foods can help build tolerance and reduce allergy risk.


Current timing guidelines

  1. General age for introduction


    • Most guidelines recommend introducing allergenic foods around 6 months of age, alongside complementary feeding.

    • Do not introduce before 4 months, as infants are not developmentally ready for solids.

    • Breastfeeding can continue alongside allergen introduction, but is not required for allergy prevention.

  2. High-risk infants

    • Babies with severe eczema or an existing food allergy are at greater risk of developing additional allergies.

    • For these infants, early introduction of allergenic foods (between 4–6 months) under medical supervision is often advised.

    • In some cases, referral to an allergist for testing before introduction may be appropriate.

  3. Specific food guidelines

    • Peanuts: Safe introduction between 4–6 months for high-risk infants, and around 6 months for others. Smooth peanut butter thinned with water or breast milk is preferred (avoid whole nuts or thick chunks).

    • Eggs: Introduce well-cooked eggs (scrambled or boiled) around 6 months. Studies show early introduction reduces egg allergy risk.

    • Milk: Cow’s milk as a drink should be avoided before 12 months, but small amounts of yogurt or cheese can be introduced at around 6 months.

    • Wheat: Introduce wheat-based foods (like baby cereal, toast, pasta) after 6 months to help lower the risk of wheat allergy.

    • Fish and Shellfish: Can be introduced around 6 months, in age-appropriate forms (well-cooked, pureed, or flaked fish).

    • Soy and Tree Nuts: Safe to introduce in smooth, ground, or paste forms after 6 months, but avoid whole nuts due to choking risk.

    • Sesame: Now recognized as a major allergen; should be introduced around 6 months (e.g., thinned tahini).


Safety precautions

  • Introduce one new allergen at a time, ideally at home, not at day care or restaurants.


  • Wait 2–3 days before introducing another allergen so you can monitor for reactions.


  • Symptoms of an allergic reaction include hives, swelling, vomiting, coughing, or difficulty breathing. Seek emergency care immediately if severe symptoms appear.

  • Avoid whole nuts, chunks of peanut butter, and hard foods that pose a choking hazard.


Key takeaway

The consensus among paediatric associations (AAP, NIAID, EAACI, BSACI, etc.) is that delaying allergenic foods increases the risk of allergy. Introducing peanuts, eggs, dairy, wheat, and other common allergens around 6 months of age—and not later than 12 months—is the most effective

way to reduce allergy risk. High-risk infants may benefit from introduction as early as 4 months under medical guidance.

Raising a child with food allergies: what every parent needs to know


Food allergies in children are becoming increasingly common, and raising a child who lives with them requires careful planning, constant vigilance, and strong advocacy. As a parent, your role extends beyond simply avoiding trigger foods—you must create a safe environment at home, at school, and in social settings while also teaching your child how to manage their condition responsibly.

Understanding food allergies in children


A food allergy occurs when the immune system mistakenly identifies certain foods as harmful, triggering a reaction that can range from mild to life-threatening. Common allergenic foods in children include:

  • Milk


  • Eggs


  • Peanuts


  • Tree nuts (almonds, walnuts, cashews, etc.)


  • Soy


  • Wheat


  • Fish


  • Shellfish


    Symptoms vary but may include hives, swelling, vomiting, coughing, difficulty breathing, and in severe cases, anaphylaxis, which requires immediate medical attention.

    Diagnosis and medical support


    If you suspect your child has a food allergy, consult a pediatric allergist. Testing may include:


  • Skin prick tests to check for reactions to allergens


  • Blood tests to measure IgE antibody levels


  • Oral food challenges (conducted under medical supervision)


    Your doctor will provide a personalized allergy management plan, often including:

  • Epinephrine auto-injectors (such as EpiPen) for severe reactions


  • Antihistamines for mild symptoms


  • Clear emergency action instructions for caregivers, schools, and family members


    Creating a safe home environment


    1. Read labels carefully – Food manufacturers are required to list major allergens. Always check ingredient lists, even on familiar products, since formulations can change.

    2. Prevent cross-contamination – Use separate cutting boards, utensils, and storage containers for allergen-free foods.

    3. Educate family members – Ensure siblings, grandparents, and babysitters understand the seriousness of the allergy and how to respond in an emergency.

    4. Meal planning – Cook at home as much as possible, and prepare safe substitutes for common foods (for example, oat milk instead of cow’s milk, or sunflower seed butter instead of peanut butter).

    Navigating school and social life


    Sending a child with food allergies into school or group settings can feel overwhelming, but preparation is key.

  • Communicate with the school – Meet with teachers, cafeteria staff, and administrators. Provide them with written medical instructions and ensure epinephrine auto-injectors are easily accessible.

  • Establish allergy-safe protocols – Request allergen-free zones if needed and discuss classroom celebrations in advance.

  • Educate your child – As your child grows, teach them to speak up about their allergies, ask about ingredients, and avoid food sharing.

  • Prepare for social gatherings – Always bring safe snacks or meals to birthday parties, sports events, and family gatherings.

    Building your child’s confidence

    Children with food allergies may feel left out or anxious about their condition. Supporting their mental and emotional well-being is just as important as keeping them physically safe.

  • Normalize their condition – Avoid treating your child as fragile; instead, empower them with knowledge and coping strategies.

  • Role-playing scenarios – Practice how to politely refuse unsafe food and how to explain their allergy to others.

  • Encourage inclusion – Work with teachers and other parents to make celebrations allergy- friendly whenever possible.

  • Connect with support groups – Meeting other children with allergies can help your child feel less isolated.

    Traveling and eating out


  • Call ahead – Contact restaurants to discuss allergies before arriving.


  • Carry an allergy card – Written cards explaining your child’s allergens can help reduce miscommunication in restaurants or while traveling abroad.

  • Pack Emergency Snacks – Always have safe food on hand in case options are limited.


    Emergency Preparedness


    Despite precautions, accidental exposures can happen. Always:


  • Keep at least one epinephrine auto-injector available at all times.


  • Teach your child (when age-appropriate) how to self-administer it.


  • Ensure caregivers, teachers, and coaches know the allergy action plan.


  • Call emergency services after administering epinephrine, even if symptoms improve.


The long-term outlook


Some children outgrow certain allergies, particularly to milk, eggs, soy, and wheat. Others, such as peanut or shellfish allergies, are often lifelong. Regular check-ups with an allergist can help monitor changes and adjust management plans.

Raising a child with food allergies is a serious responsibility, but it does not have to limit their opportunities or joy. With preparation, education, and advocacy, children with food allergies can lead healthy, active, and fulfilling lives.
