I'm getting married in July in the evening. We decided early on we did not want chldren there. A cousin started telling me a few months ago she was bringing her daughter, which I kindly told her there would only be adults there. But since she's traveling in for a few days, we could arrange for a sitter at the hotel, if she'd like. She agreed to that. A couple other family members on my FI's side asked if there would be kids and were understanding when I told them no. Our invitations went out Monday and I just received a message from my uncle that his son and wife were bringing their kids and he was concerned about what the invitation stated. He went on about the memories they will have being part of the wedding. Keep in mind I don't know the children. I also feel like my memories of my wedding should be considered. Don't mean to sound like a bridezilla, but no one should assume it's okay. Our save-the-dates never included the names of chlldren I probably should also mention, this uncle is our officiant.
Does anyone have suggestions on how to handle this? I'm stressing!
