We love your kids—we really do. But we want our wedding to be your night off! We know that this may be difficult for some, being in the middle of the week, and fully understand if this means you can't stay long or can no longer make the celebration.
If your invitation says “and Guest,” then yes. If not, we would prefer if it was just you or that you ask first.
We'd like you to look nice but by all means be comfortable! It is a party after all :)
