One my bridesmaids and I are really close with one of our college professor's family. They have 4 children who will be aged 14, 12, 10, and 8 at the time of the wedding. I'm really close with the 14 and 12 year old and want them there at my wedding, and while I also have a good relationship with the 10 and 8 year old, I know they will spend the entire reception hanging on one of my bridesmaids and completely ruining her night. She's too nice to tell them to go away (and I love her for it). Is it acceptable for me to ask my professor's wife not to bring the 10 and 8 year old, or at least a nice way of saying it? I thought about making up a rule that only children over the age of 12 other than immediate family are invited, but that's not really true because there will be at least 4 other kids at the reception who are clearly not my immediate family. I have absolutely no problem with them being there except for the fact that they will be a nussiance to my poor sweet bridesmaid, and I'd really like to just avoid putting her in that situation. Any suggestions?
