We absolutely love your kids. If you want to bring them, you are more than welcome to. It is your preference.
The dress code is more of a dressy casual. We want you to be comfortable and still feel your best. Although the wedding is on St. Patrick's Day, we would really love it if there were no leprechauns - THIS MEANS YOU TYLER AND UNCLE DAVID! If you want to wear green, go for it, just not green suits.
If your invitations says your name plus guest, of course bring that special person. However if it does not, we would really love it if it was just you.
