In a nutshell
Know the signs of a reaction and when to call for help.
Food allergies are common in children.
This is general information — always follow medical advice for your child.
Tip 1 Common allergens
- 💡 Milk
- 💡 Eggs
- 💡 Peanuts and tree nuts
- 💡 Fish and shellfish
- 💡 Wheat
- 💡 Soy
- 💡 Sesame
Tip 2 Signs
Hives, swelling, vomiting, or tummy pain can be signs. Breathing difficulty, swelling of the tongue or throat, or collapse are signs of anaphylaxis — call emergency services.
Tip 3 Diagnosis
See a doctor for testing rather than cutting out foods unnecessarily.
Tip 4 At school
Share an allergy action plan and medication with school.
Tip 5 Introducing allergenic foods to babies
Current guidance in many countries suggests introducing common allergenic foods, such as egg and peanut (in a safe form like smooth peanut butter mixed into food), around six months as part of weaning, rather than delaying them. Babies with severe eczema or existing food allergies may need medical advice first. Introduce one new allergen at a time and keep offering it regularly once tolerated. Never give whole nuts to young children due to choking risk.
This is general parenting information, not medical advice. Every child is different — talk to your paediatrician, family doctor, or a qualified specialist about your child’s health, development, or behaviour. In an emergency, call your local emergency number.
