To request no kids on the wedding invites?

[Curlyhepburn]

The wedding is a while off yet but just planning now and it occurred to me that I dont know how to go about it, we have 3 kids of our own between us, youngest will be 13 at the time and we are both clear on not wanting very young kids/babies.

I know this isnt always popular with families and I wondered if its reasonable to include a note of this in the info card to go out with the invites?
Am I being daft?

I did not have children at my reception apart from the bridesmaid (daughter of sister-in-law). I wanted my friends to enjoy the event and not spend all night babysitting. Most of my cousins were older than me so did not come, and my friends were not married at the time nor had children of their own. If you give plenty of notice, they can find somebody to have their children during the event. If they don't want to come with out children then they don't come. I married nearly 20 years ago in a church. You can not stop children attending the church as they are open to the public, but if in another venue you can request from the start no children. It is your day - enjoy and stick to your decision.
