Start With the Invitation, Not the Buffet

The most useful allergy conversation happens weeks before the first party bag is handed out. When you send invitations, add a short line asking parents to tell you about any food allergies, intolerances or dietary needs by a set reply date. Something as simple as "Please let me know by Friday 12th if your child has any allergies or dietary requirements — it makes planning so much easier" does the job without making anyone feel like a nuisance.

Ask this of every guest, not just the families you already know. Allergies can develop at any age, and a child who could eat anything last summer may be avoiding a new ingredient this year. Chasing up a few non-replies with a quick text is far less awkward than discovering a serious allergy at the table.

What to Ask, and What to Do With the Answers

A general question often gets a vague answer, so be specific. Useful things to confirm include:

• Which foods must be avoided, and whether contact or traces are a problem as well as eating.
• How severe a reaction has been, and what the plan is if one happens.
• Whether your child carries an adrenaline auto-injector, and who will hold it during the party.
• Which foods are safe, so you can make sure there is something they genuinely enjoy.
• Whether a parent would prefer to stay, or send a labelled portion of safe food.

Write it down and keep it somewhere you can check quickly — a note on your phone works well. If you are hiring a bouncy castle or entertainer for the afternoon, none of this needs to change your plans, but it does mean you can brief any adults helping you serve food.

Keep Ingredient Labels Visible and Readable

At a party, food gets decanted into bowls and the packaging disappears into the bin. That is exactly when mistakes happen. Where you can, keep the original packaging, or a photograph of the ingredients panel, next to each dish. A tray of sausage rolls is easy to trust until you realise nobody checked whether the pastry contains milk or egg.

For anything homemade, write a small card listing what went into it — including the oil, the stock cube and the icing. Handwriting on a bit of card is fine; clarity matters far more than presentation. If you are using a mix or a ready-made item, check the label on the day you buy it, since recipes and factories change. Vague terms such as "may contain traces" or "made in a factory that handles nuts" are worth showing to the parent rather than deciding on their behalf.

Ask guests not to bring sharing bags of sweets or snacks unless they still have the packet. A bowl of loose sweets with no wrapper is impossible for an allergic child to judge.

Separate Serving Areas to Reduce Cross-Contamination

This is the single most effective thing you can do during a busy party meal. Give foods that contain a common allergen their own table, their own serving spoons and their own bowls, with clear space between them and the rest. If you can, serve the allergen-free options first, before anything else has been handled, and keep those dishes at the opposite end of the table.

• Use separate tongs, spoons and jugs for each dish, and never swap them between plates.
• Put crisps, biscuits and bread in their own bowls rather than mixing them on one platter.
• Ask children to wash their hands before eating — soap and water removes food proteins far better than hand gel.
• Cut the birthday cake with a clean knife, and keep a separate slice or a cupcake in a labelled box for the allergic child if the cake is not safe for them.
• Wipe the table and any shared serving surface before the food goes out, especially if craft glue, playdough or pet food has been around.

It helps to have one adult keeping an eye on the food table rather than leaving children to help themselves. That person can plate up for the allergic child and quietly make sure nothing has been borrowed from the wrong bowl.

Make Sure the Allergic Child Still Has a Good Time

Nobody wants to be the child with the different plate. Where possible, choose at least one or two items that everyone can eat, so the safe food does not look like a consolation prize. If the child needs to eat their own food from home, seat them with a friend rather than on their own, and keep the conversation light.

A quiet word with the child before the food comes out can help too: "Your mum said these are yours, so this bowl is just for you — shout if you need anything." They feel seen, and you get a heads-up if something has gone wrong.

Finally, keep the allergic child's parent in the loop with a quick message after the party. A short "she ate well, the cake was fine, no problems at all" takes ten seconds and means a great deal to a family who spends most social occasions on alert.
