What information should I ask for in a party RSVP?

The RSVP questions that matter

The point of an RSVP is to find out who will actually be at your party and what you need to sort out with each family before you shop, order or set up. A plain yes or no won't tell you whether a sibling is coming, whether a parent is staying for food, or whether a child needs to avoid certain foods. A few short questions answer all of that.

Most RSVPs cover five things: who is coming, whether siblings are included, food requirements to discuss, whether a parent will stay or drop off, and a phone number for the party day. For an adult party, ask adult guests directly about food. For a sleepover or drop-off party, you will need more detail from each family, which you can collect in a follow-up conversation after the RSVP.

The questions work best when the invitation has already set out the arrangements. If siblings aren't included, if there's a limit on guests or if a parent must stay, say so on the invitation. That way families are answering a clear question and won't have to guess what you will allow.

• Names of everyone coming, plus separate totals for children and adults
• Whether siblings are coming, if siblings are invited
• Whether a parent or carer will stay or drop off
• Any food allergies, dietary requirements or other needs that could affect your plans, with “none” as an option
• The best phone number to reach the family during the party
• A reply date set before your shopping or ordering deadline

How to ask who is coming: children, siblings and adults

A total such as “3 coming” leaves you guessing. Is that the invited child, a sibling and a parent, or two adults and one child? Ask for names, then keep a separate total for children and adults. Names also help you tell whether two messages from the same family refer to the same people.

Decide whether siblings are welcome before you send the invitation, and say so. If they are, ask for each child's name so a sibling doesn't get lost in a number. If they aren't, ask families to check with you before bringing anyone extra.

If you've decided siblings can come, check that food, seating, activity places and favors stretch to the extra children, then say so clearly on the invitation. If they can't, keep the check-with-me approach above. Our birthday invitation wording when siblings are welcome has examples.

Ask about adults directly, especially if you are providing food or seating for them. Whether a reply of zero adults is fine depends on what your invitation said about staying or dropping off.

How to ask about food allergies and other needs

Ask every family about food, rather than waiting for someone to mention an allergy. An open question works better than a list of common allergens on its own. Here is wording you can copy: “Are there any foods or ingredients your child needs to avoid? Please tell me about food allergies or other dietary requirements, and let me know if you'd prefer to discuss the details privately. If there are none, please write ‘none.’”

Keep the first question short. A reply like “dairy” or “nuts” gives you a place to start, but it doesn't tell you what to buy or how to serve it. Follow up privately: “Which ingredients or products should we avoid, and which foods are you comfortable with us serving? What should we know about preparing and serving the food? I'll send the proposed menu before I shop.” If you're not sure whether the family is describing an allergy, an intolerance or a preference, ask how they describe it. Don't work it out from one word, and don't decide what's suitable based on a description such as “mild.” Talk about shared preparation areas, utensils and serving dishes too, and write down what the family asks you to do.

When a family confirms an allergy, the RSVP is only the start. Agree the specific products, how food will be prepared and served, and send your menu before you shop. Follow up on blank or unclear answers too. See how to plan a party around a guest's food allergy.

A blank field doesn't mean “no allergy.” Text or call before you settle the menu, and mark the answer as unconfirmed until the family replies. Don't fill in “none” yourself.

Food isn't the only thing to ask about. Invite families to mention any other needs that could affect your plans. If a child is being dropped off, write down the parent's instructions and note which adult will receive them. If you're unsure what a family means, ask.

Follow up privately about what the child needs to join in, be comfortable or get around, and ask only what affects your plans. You don't need a diagnosis or extra personal details. Our guide on how to ask parents about party accommodations has questions you can use.

Getting a contact number and setting a reply date

Ask which number you should use during the party, not just how to reply. At a drop-off party, this is the number you'll need if plans change or pickup runs late.

A week before the party is a reasonable starting point for the RSVP deadline. Make it earlier if a venue, supplier or shopping plan needs it. Leave time between the reply deadline and your final-count deadline to chase missing details. Send the food question with the invitation itself, so families answer it alongside attendance.

For families who haven't replied, send a direct reminder three or four days before your deadline, then think about calling if you still need an answer. Keep “no reply” separate from confirmed guests. If there's a strict limit on numbers, check you still have space before accepting a late yes.

Example RSVP form and worked headcount

Here is an example response form you can adapt. Change the wording to match the arrangements on your invitation.

Name of invited child: ____. Will they come? Yes / No. Siblings: siblings are welcome; please list the name of any sibling coming: ____. (If siblings aren't included, replace this with: “Please check with me before bringing anyone else.”) Will an adult stay? Number of adults and their names: ____ (enter 0 for drop-off). Foods or ingredients your child needs to avoid, or other needs I should know about: ____ (write “none” if there are none, or ask me to call). Best phone number during the party: ____. Please reply by [date], before we order the party food.

Illustrative worked example: you invite 8 children, not counting the birthday child. Siblings are welcome, and parents may stay or drop off. Six families say yes, one says no and one hasn't replied. Two of the families saying yes are bringing a sibling, and three adults are staying. Confirmed children are the 6 invited children, plus 2 siblings, plus the birthday child, which makes 9. Confirmed adults are the 3 staying adults, plus the 2 adults in the host household, which makes 5. The family that hasn't replied stays on a separate line until you hear from them. Only add people who aren't already counted, so if the birthday child's own brother or sister is attending, add them once as household members, not as guest siblings.

What to do with the replies

Keep a host copy with everything you need: guest replies, contact numbers, family instructions, food notes, timing, supplies and where they are, helper jobs, pickup information, cleanup tasks and any unanswered questions. Mark anything that still needs confirming. Give helpers only the details they need for their jobs.

What you send to families is separate. That includes the date, time, address, RSVP details, relevant food information, what to bring and pickup arrangements. For a sleepover, add drop-off and pickup times, sleeping arrangements, any relevant pet or activity details and the host's contact number. Discuss individual food, health or comfort needs privately rather than in a group message.

Update your notes as replies arrive, after any shopping or menu change, the day before the party, and whenever contact or pickup arrangements change. Tell affected families about any change they need to act on. On party day, only update the notes if an arrangement changes.

Use whichever format you will actually check during party week. A printed copy can stay with the setup supplies. A digital note is easier to change as replies come in. Some hosts use both. If you use the sleepover parent communication checklist, fill in the party details, record each family's reply and use its invitation and reminder templates to share the confirmed arrangements. Keep supplies, helper jobs and private family notes on your own copy. The page's checkmarks aren't saved when you leave, so keep your completed notes somewhere else.

RSVP checklist before you shop

Use this list to keep track of your replies and decisions. Ticking it off is a record of your planning, not a guarantee about the food.

• Invitation states the sibling policy, guest limits and whether a parent must stay
• RSVP asks for names, child and adult totals, stay or drop-off, food and other needs, and a party-day phone number
• Reply date is set before your shopping or ordering deadline
• Families who haven't replied are listed separately and have been reminded
• Blank and broad food answers have been followed up privately
• Proposed menu, including drinks, cake and edible favors, has been confirmed with families who need it
• Adults serving food and receiving drop-off instructions know the agreed arrangements
• Host copy is up to date and unanswered questions are marked
