I got some good advice on RSVPs so now tell me the best way to handle a person just assuming children are invited. Invitations went out addressed to "Mr. and Mrs. Doe" but I just got an email from Mrs. Doe telling me that she and her 4 year old granddaughter (whom she is parenting) will be coming to the wedding. The only other person with a child that age has already told me that he would not think of bringing his son to a wedding. The ring bearer is 5 (no flower girl) and there are 2 children invited that are 13. I don't believe any other guests have children younger than that. Do I keep my mouth shut and hope the little girl is better behaved than she has been in the past or do I tell her grandmother that the wedding is adults only? I can't use the excuse that there is not enough room/food since the child is obviously taking the husband's place.
