Allergic reactions in children can turn from a minor irritation into a medical emergency within minutes. The immune system releases a flood of chemicals that narrow airways, drop blood pressure, and swell body tissues. Without fast treatment, allergic reactions in children can turn life-threatening within minutes.
Common Allergy Triggers for Australian Kids
A handful of allergen triggers cause most allergic reactions in children. These include:
Nuts
Food intolerance, particularly eggs and dairy
Wheat, soy, and sesame
Seafood
Insect stings and bites
Medication
Latex
Signs and Symptoms of an Allergic Reaction
Anaphylaxis and allergic reactions in children run along the same spectrum. A reaction that stays around the skin, face, mouth, or gut is a sign of allergies in children. Once it reaches the airway, breathing, or circulation, it is anaphylaxis. Most allergic reactions in children occur within minutes to two hours of contact with the trigger. Symptoms of a severe allergic reaction include:
Hives (raised red welts), redness, itching, and swelling around the lips, eyes, tongue, or face.
Cramping, nausea, vomiting, and loose stool.
A hoarse voice, a wheeze, a persistent dry cough, throat swelling, tightness, or noisy breathing.
A fast or weak pulse, pale or blue-tinged skin, clammy hands, dizziness, sudden tiredness, or collapsing.
Paleness
Becoming suddenly unresponsive
First Aid for Anaphylaxis in Children
Anaphylaxis is time-critical. The first aid response for allergic reactions in children is:
Lay the child flat with their legs raised where possible. If it is hard for them to breathe, let them sit up with legs straight out instead.
Do not allow them to stand or walk, even if they feel better. Hold babies and toddlers flat in your lap instead.
Give them an adrenaline or epinephrine injection if they carry one with them as outlined in their ASCIA action plan for anaphylaxis.
Call 000 and ask for an ambulance.
Give them a second dose of adrenaline after five minutes if there is no improvement or the child gets worse.
Start CPR if the child stops breathing normally or can no longer respond.

FAQs
How Common Are Food Allergies?
About 1 in 10 infants has a diagnosed food allergy, according to the Australasian Society of Clinical Immunology and Allergy. The number falls to around 1 in 20 among school-age children, because cow’s milk, egg, wheat, and soy allergies can resolve as the immune system matures.
Can an Allergic Reaction Look Like Eczema?
Yes. Eczema is a long-term skin condition with dry, itchy patches that come and go over weeks, while an acute allergic flare brings sudden raised welts within minutes of contact. Track when each rash appears against recent food or activities to help your GP confirm which it is.
Can Allergies in Babies Look Different?
Yes, babies and toddlers are more likely to appear pale or be unresponsive than older children.
