We love your kids! - We really do, but we want our wedding to be your day off. The kids you WILL see at the wedding will be Kids who will participate in the ceremony.
If your invitation says "And Guest" then yes, if not we would prefer if it was just you.
Formal, please. But we want you to feel comfortable, so if those shoes are too high or that top button is too tight, let it all hang loose
We'd love you to have as many memories as you want of such a beautiful day in our lives. Just remember to turn the flash off during the ceremony.
