When to Call Your Pediatrician

Contact your pediatrician soon if your toddler has repeat tummy upset, rashes, or vomiting after the same food, or if you suspect an intolerance that is affecting growth or sleep.

What is the difference between a food allergy and a food intolerance?

A food allergy is an immune-system reaction to a food protein and can be serious, even from a tiny amount. A food intolerance is a digestive issue, like trouble breaking down lactose, causing discomfort but not danger. Symptoms, timing, and severity differ, so your pediatrician can help confirm the cause with a careful history and testing if needed. (57 words)

What are the most common food allergens for toddlers?

Nine foods cause about 90% of childhood reactions: milk, eggs, peanuts, tree nuts, soy, wheat, fish, shellfish, and sesame. Peanut and egg are among the most frequent triggers in the 1–3 age range. The reassuring part is that many children outgrow milk and egg allergies by school age, while others persist and need longer-term management. (59 words)

When should I introduce allergenic foods to my toddler?

Most babies can start allergenic foods around 6 months of age alongside other solids, once they can sit up and swallow safely. Introduce one new allergen at a time and keep it in the diet regularly. Higher-risk infants with severe eczema or egg allergy should talk to their pediatrician first about supervised, earlier peanut introduction. (58 words)

Can my toddler outgrow a food allergy?

Many do. Research suggests roughly 80% of children with milk or egg allergy outgrow it by age 5, while peanut, tree nut, fish, and shellfish allergies more often persist into adulthood. Your pediatrician can re-evaluate with supervised testing over time rather than assuming the allergy is permanent, which helps expand your toddler’s diet safely. (59 words)

How is a food allergy diagnosed?

Diagnosis starts with a detailed feeding and symptom history from you and a physical exam by your pediatrician. Skin-prick or blood tests may be used to check for specific antibodies, but they are interpreted alongside real symptoms — a positive test alone does not confirm allergy. An oral food challenge in a medical setting is the most definitive test. (60 words)

What should I do if my toddler has a severe reaction?

If you see breathing trouble, throat swelling, widespread hives with vomiting, dizziness, or fainting, suspect anaphylaxis. Use a prescribed epinephrine auto-injector immediately and call emergency services — do not wait. Keep your child lying down with legs raised if faint, and stay with them. Always carry two doses if your pediatrician recommends it for your toddler. (60 words)
