This is the single most anxious question in invitation wording, and the anxiety is justified: you are telling people their children are not invited, in writing, in advance. Done badly it reads as a rebuke. Done well it barely registers.
Say it once, warmly, in the same voice as the rest of the invitation.
The rule that makes this easier
Address the invitation to the people who are invited. An invitation to “Sarah and James” means Sarah and James. An invitation to “The Okafor Family” means everybody.
Traditional etiquette holds that this alone is sufficient and that stating it outright is unnecessary. Traditional etiquette is wrong about how people read email in 2026. Name the invited guests and add a line — belt and braces prevents the awkward phone call.
Wording that works
Warm and plain
We love your little ones, but this one’s just for the grown-ups.
We’re keeping our celebration adults-only, so you can have a night off.
Adults only, please — we hope this gives you an excuse for an evening out.
These work because they frame the restriction as something offered to the guest rather than taken from them. The night-off framing is genuinely how many parents receive it.
Neutral and clear
Adults only (18+)
This is an adults-only celebration.
Whilst we love your children, this is an adults-only occasion.
Plain is fine. Most guests read it, understand, and think nothing more of it — the awkwardness is almost entirely on the host’s side.
Formal
We respectfully request no children under 16.
The ceremony and reception will be adults only.
When there are exceptions
Immediate family, nursing infants, and the wedding party are the usual carve-outs. State them, or you will be asked about them individually.
Adults only, with the exception of immediate family and nursing infants.
Aside from our nieces and nephews in the wedding party, we’re keeping the day adults-only.
Wording that backfires
- “No children allowed.” “Allowed” makes it a rule rather than a choice, and reads as a telling-off.
- Explaining at length. A paragraph of justification about venue capacity and licensing invites debate. One line does not.
- Apologising repeatedly. “We’re so sorry, we hope you understand, we feel terrible” signals the decision is negotiable.
- Jokes at children’s expense. “No screaming, no sticky fingers” lands badly with parents, who tend to like their children.
- Saying it twice on the same card. Once is firm; twice is defensive.
Where to put it
Not in the headline, and not buried. The natural home is with the RSVP details, alongside the other practical information — it belongs with dress code and parking, not with the celebration itself.
[DAY], [DATE] at [TIME]

RSVP by [RSVP DATE]
On a digital invitation you have more room than on a card, so a short sentence on the RSVP page works even better — guests see it exactly when they are deciding who is coming.
The conversations that follow
A small number of guests will ask anyway. Two things make this survivable:
- Be consistent. One exception becomes common knowledge within a day, and then every other parent has grounds to ask. If you make exceptions, make them by a category you can state — immediate family, under-ones — not by who asked most persuasively.
- Have one sentence ready. “We’d have loved to but the numbers just don’t work — we hope you can still come.” Do not elaborate. Elaboration reopens the question.
Expect a few declines. Some parents genuinely cannot arrange childcare, and that is a real constraint rather than a protest. If your guest list is heavily young-family, consider whether the restriction costs you more attendance than it buys you calm.
The kind alternative
If you want an adults-only evening without excluding families entirely, split the day:
Children are very welcome at the ceremony and lunch.
The evening reception, from 7pm, is adults only.
Or arrange childcare at the venue and say so — “There’s a supervised room for under-10s during the reception” converts a restriction into a service, and parents remember it.
