I passed out a few invitations to my coworkers. We work in a small office so we only have a few employees. I addressed the cards to each coworker and a guest. One of my coworkers (who I am not really close to...invited her basically as a courtesy so she wouldn't be left out) returned her RSVP card and included herself, her date, her three children, and her date's child because she "couldn't leave him out." I was pretty taken aback by her boldness. My fiance is upset about this and says I need to tell her she can't bring all of the kids because they weren't invited and we are on a strict budget. My mom, who also works in my office, thinks I should let it be. I am concerned about the cost per plate charge and also about her children running wild. They are ages 3 and under and not very well behaved. There will only be a handful of children attending the wedding and they are either participating in the ceremony or are close relatives. Everyone else is getting childcare. Does anyone have any advice on what I should do? I feel like I've been put in a pretty awkward spot. I see this girl everyday and work in close quarters so I don't want to cause a big issue yet I don't feel I should have to pay for six guests when the invitation clearly indicated two. Help!
