When to announce that it is a no-kid wedding?

I don't think you necessarily need to announce it. You can just address the invitations to the people invited. Some people put a note on their wedding website about adult only in the FAQ section, but we never announced it and simply addressed the invitations to the names of the people invited

You don't really make an announcement about it. You would just address the save the dates and invitations to who you are specifically inviting. For our invitations, we put X number of seats have been reserved which made it even more clear who was invited. We also included on our website under the FAQ section that while we love everyone's children that we requested an adult-only wedding.

Just like Hanna said: never a formal announcement. But be clear when addressing envelopes. MOG and MOB are good resources to spread the word/reiterate the facts! On the website under the reception details you can consider including adults-only language.

As some have said, I would just notated on the invitations. That's a good time.

I agree with MOG and MOB spreading the word, I feel like word of mouth is one of the best and easiest ways to get the information out there, especially since you have time yet.

Our wedding will be adults only with the exception of my two nieces who are flower girls. We've made it clear from the start that kids are not invited.

We've told people in-person/text messages what our plans were and that we are keeping it adults only. Most have received it very well. When we sent out our Save the Dates and New Date cards, the envelope was addressed to Mr. and Mrs. not 'Smith Family'.

The invitations will be sent the same way.

On our website, under the FAQ, we put "Can I bring my children? We love ALL of your children, however, we have decided to make this an adults-only celebration. We hope you understand!"

We just heard from FH best friend that his parents likely won't come because they will have to watch the kids. It will be hard for some who don't have a regular babysitter or family in town help out but we are sticking to our plan.

View Quoted Comment Thanks for this input! We are definitely not going to compromise on having kids at our wedding, either. I just don’t want to deal with that hassle and I’d like our guests to enjoy themselves. I like your way of addressing the invitations, we’ll do the same for ours!

I put mine on the RSVP card in small print “adults only celebration “
I also mentioned it on our wedding website

View Quoted Comment Perfect! Thank you 😊

I sent out invitations without mentioning it first, for our original date, and I had people RSVP with their children’s names. Even after I specifically addressed them by name on the invite. When I sent my second round of invitations for our postponed date, I added the line about adults only so there was no confusion.

On your invitation just make it clear that its an Adult Wedding
