Allergenic foods: introducing a new food and recording reactions

Planning allergenic foods from around 6 months, keeping useful notes and recognising severe reactions that need emergency help.

At a glance

Starting solids does not mean trying every food at once. A clear introduction routine makes it easier to tell a healthcare professional what was eaten if a reaction occurs.

Make an individual plan when risk is higher

Discuss introductions with your care team if your baby has a diagnosed food allergy or eczema, or a family history of allergic conditions. Do not retry a suspected trigger at home to test the reaction. An app’s “no problem” mark is not a medical assessment.

Introduce one at a time in a suitable form

NHS guidance advises introducing potentially allergenic foods one at a time from around 6 months. Avoid several new allergens in the same meal so you can identify what is new. Do not serve whole nuts or large spoonfuls of peanut butter. Texture and preparation must also account for choking safety.

A food record is not a diagnosis

Note the food and ingredients, time offered, approximate amount and any symptoms noticed. Keeping packaging may help explain ingredients. Do not label one unsettled episode as an allergy or remove broad food groups without advice. Describe a suspected reaction to the care team.

Do not stop to write during a severe reaction

Get emergency help for swelling of the lips, mouth or throat, breathing difficulty, marked floppiness or unusual unresponsiveness. Follow any prescribed allergy emergency plan. Discuss continued inclusion of tolerated foods with your team. This guide is not a home allergy test or treatment plan.
