We love your kids—we really do. However, the wedding is in the morning/early afternoon, and any activities the reception will most likely be adult only. If you still choose to bring them, we need you to include them in your RSVP to get a proper head count.
If your invitation says "and Guest," then yes, if not, we would prefer if it was just you. We are trying to keep this an intimate affair.
Cocktail, 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.
