I'm not on here very much but I really need your help. We just got an RSVP from FI's cousin (who I've never met and he hasn't seen in about 10 years). We actually thought the cousin wasn't coming. Turns out he and his wife are coming and they are bringing their baby. We clearly put on the invitation Adult Reception. I told FI to talk to his mom about it but I feel like they are too afraid to say something to him. I don't feel like it's my place to say something since it's not my cousin and I don't even know the guy. My mom told me she has no problem calling him and letting him know that the reception is not for children.
