I'm having a very formal ceremony and reception and do not want any kids under 10. My FH has a groomsman (who is also his cousin) who has a son that is 3. He is very wild so I absolutely do not want his son there, but he's traveling 8 hours to come. What should I do? He's already planned to come and stay an entire week, talking about taking his son to the beach since they don't live near one, etc. His son is absolutely traveling here with him, but I have no idea how to tell him he can't come to the wedding.
Also, to add to it, my FH's aunt is having a baby in February... 4 months before my wedding. She also lives 8 hours away. Definitely do not want a newborn at my wedding either, but it's his aunt. And she is so excited about the wedding.
My FH doesn't want conflict with them so he thinks we should just let them come. I have no problem telling my side of the family that kids aren't invited, but it's a little different with his side. Hoping someone has been in a similar situation. Is there any kind of solution I can come to here?
