How to Say Adults Only, and When Kids RSVP Anyway

Saying "adults only" is the easy part. Most couples manage a kind sentence on the invitation and another on the wedding website. The hard part comes three weeks later, when a reply arrives that says "2 adults, 2 kids" and you have to decide what to do about it.

This guide covers both. First, how to say adults only on your invitation, your wedding website and your RSVP, with wording you can copy. Then what to do when someone RSVPs their children anyway, including how to stop it happening in the first place.

TL;DR:

• Say it in three places: the envelope, the wedding website FAQ and the RSVP form.
• The envelope does the most work. Address it to the people invited, by name, and nobody else.
• Keep the wording short and warm. You don't owe anyone a long explanation.
• If kids show up on an RSVP anyway, call or message the guest privately, kindly and quickly.
• An RSVP where guests add people by name, with their age, catches most of these before they happen.

Decide first, then say it once, the same way everywhere

Before you write a word, decide exactly who counts as a child and whether there are exceptions. Common ones are your own children, nieces and nephews in the wedding party, and nursing babies. Whatever you decide, say it the same way on the invitation, the website and the RSVP. Guests notice when the three disagree, and the one that's most generous is the one they'll quote back to you.

If you're still deciding whether to invite kids at all, our guide to inviting kids to a wedding walks through both sides.

How to say adults only on the invitation

The clearest signal is who the invitation is addressed to. Write the names of the people invited on the envelope and on any inner card: "Mr. and Mrs. Alvarez", or "Dana and Chris". Leave off "and family". That often does the job before anyone reads a word of wording.

If you'd like a line on the invitation itself, keep it to one:

"We love your little ones, but this celebration is just for the grown-ups.""Adults-only celebration.""We have reserved two seats in your honor."

The last one is subtle and works well when you name a number on every invitation. It also helps with plus-ones, not just kids.

How to say adults only on the wedding website

The website is where you can explain a little more, because guests go there with questions. Put it in your FAQ, and phrase the question the way a parent would ask it.

Are kids invited?

"We love your children, but we've decided to make our wedding an adults-only celebration. We hope this gives you a night off to relax and dance with us. Thank you for understanding."

Are there any exceptions?

"The only children at the wedding will be those in the wedding party."

Can you recommend a babysitter?

"We've asked around, and a few local sitters are listed below. Book early, as Saturdays in June go fast."

I'm nursing. Can I bring my baby?

"Of course. Babies in arms are welcome. Let us know on your RSVP so we can save you a quiet spot."

Delete the exceptions you aren't making. A clear no is kinder than a vague maybe.

How to say adults only on the RSVP

The RSVP is where the misunderstanding usually happens. A paper card with "___ will attend" invites guests to write in any number. A form with a free text box for names invites them to write in any names.

A better RSVP form does three things:

1. Shows the guest their own name already on it, so it's clear who the invitation is for.
2. Tells them how many people they can bring, if any.
3. Asks for each extra person by name and age, so a child can't be added by accident.

That's how replies work in WhiteClover. In your RSVP settings there's a switch for whether children are welcome. When it's off, guests can only add adults to their reply. If someone tries to add a child, the form tells them the invitation is for adults only and asks them to remove the child before sending. Each guest's plus-one limit is set by you, and you decide whether children count toward it. Babies never do.

It isn't foolproof. A guest can still mark a teenager as an adult, and nothing stops someone turning up with a child on the day. But it turns most "we thought the kids were included" moments into a polite message on the form, weeks before the wedding, rather than a conversation at the door.

What to do when someone RSVPs their kids anyway

If it happens, here's how to handle it without a falling out.

1. Assume it's a misunderstanding

Most of the time it is. Someone skimmed the invitation, or their kids have come to every family event and they didn't expect this one to be different. Starting from that assumption keeps the conversation warm.

2. Reach out privately, and soon

Call or text the guest directly, within a day or two. Don't let it sit until the week of the wedding, and don't put it in a group chat. If the guest is closer to your partner or a parent, let that person make the call.

Wording you can adapt:

"Hi Jess! We just got your RSVP, thank you. I wanted to check in, because our wedding is adults only and we've kept it to the grown-ups across the board. We totally understand if that makes it tricky, and we'd still love to have you and Mark there.""So happy you can come! Just a heads up that we're keeping the wedding adults only, with no exceptions besides the flower girl. If it helps, we've listed a few babysitters on our website."

3. Hold the line, kindly

If you make an exception for one family, expect other parents to hear about it. Exceptions you announce up front, like the wedding party or nursing babies, are fine. Exceptions you make quietly for one guest are the ones that cause trouble.

4. Accept that some guests won't come

Some parents can't find childcare, especially if they'd be traveling. That's a real cost of an adults-only wedding, and it's fine. Thank them for letting you know and move on. Our guide on how many guests usually decline has more on planning around it.

5. Update your list

Remove the kids from your head count, and make sure your caterer, venue and seating plan reflect the change. In WhiteClover, children who were already on replies before you switched the setting stay on them, and the reply is flagged so you can see it and follow up. You can also filter your guest list to show children.

Common snags

Saying it once, kindly

An adults-only wedding is a reasonable choice, and most guests will respect it if you say it clearly and early. Address envelopes by name, answer it in your FAQ, and use an RSVP that asks who's coming by name, so a child can't be added by accident.

If you want a reply form that does that for you, see how online RSVPs work in WhiteClover, or start your guest list free.

Frequently asked questions

How do you politely say no kids at a wedding?

Address the invitation to the people invited, by name, and add one warm line on the invitation or website, such as "We love your little ones, but this celebration is just for the grown-ups." You don't need to explain further.

Is it rude to have an adults-only wedding?

No. Couples choose it for budget, venue or atmosphere, and those are all fair reasons. What makes it feel rude is inconsistency, like exceptions made quietly for one family, or wording that's vague.

What do I do if a guest RSVPs with their kids?

Contact them privately within a day or two, assume it's a misunderstanding, and explain kindly that the wedding is adults only. If they can't come without the children, thank them and accept it.

Should I put "adults only" on the invitation?

You can, but the names on the envelope matter more. Address it only to the people invited, and if you add a line, keep it to one short sentence. Put the longer explanation on your wedding website.

Are babies included in an adults-only wedding?

Only if you say so. Many couples make an exception for babies in arms, especially for nursing parents. Decide early and put it in your FAQ.
