We are having a small, elegant, intimate wedding with 25 people. It is an adults only occasion and this has been communicated to the guests. My fiancé's good friend from out of town just called to say that they are unable to find anyone to keep their young children and might need to bring them. If not, they cannot attend. My fiancé, of course, told him that he wanted him to be there no matter what. I am extremely anti-children. Everyone attending the wedding knows this about me. I do not want children at our wedding. Any suggestions or advice?
